VIEWLOG 2.3 Upgrade Notes Update Notes: Version 2.3.79 Aug. 13, 2002 - Fixed a bug reading non-standard, tab-delimited, LAS files. Version 2.3.75 July 22, 2002 - Changed the handling of transparent objects in the 3D window. VIEWLOG now auto-sorts transparent OpenGL objects so that they are drawn after the non-transparent objects, resulting in better viewing. Version 2.3.72 July 19, 2002 - Added a function to the Log Display Menu that allows a quick reset of all custom log track widths. Click the button in the Track Tab of the Log Display Menu to reset all track widths. Once reset, the default track width will be used for all logs in the file. Version 2.3.67 July 15, 2002 - Fixed a problem which caused a overflow when importing large shape files. The overflow was due to changes related to the new user interface controls introduced in 2.3.24. Version 2.3.64 July 8, 2002 - Improved printing performance by reducing memory requirements with large (more than 5000 x 5000 rows and columns) grids. Note: Printing gridded parameters of this size can result in print spool files exceeding 400 MB! - Fixed a bug that could cause contour lines on gridded parameters on cross section to disappear - Fixed a bug that prevented the autoscale function from working on newly created gridded parameters. This also fixes a problem auto scaling integer grids that are incorrectly defined. - Fixed a bug that created a extra blank layer created when importing a shape files. - Correctly reset the mouse cursor after importing map layers - Fixed a bug that caused a crash when pasting map layers between large files. IMPORTANT NOTE:------------------------------------------------------ The VIEWLOG software now uses a new hardware key system recognized by the "white" outer key casing (previous hardware keys were green). Only the new software, Version 2.3.61 or later, will work with the new white keys. The new software versions will also work with the old “green” hardware keys, so please upgrade all VIEWLOG users to the new software to avoid confusion in offices where both green and white keys are in use. ------------------------------------------------------ Version 2.3.61 June 27, 2002 - Added new options to the Data Source, Mark function. The Mark function, which is used to write information back to the database, can now write to any table, not just the borehole data source table. In addition, the Append option can be used to create new records in the database if non exists. - Added a new option to Parameter Menu, Grid Tab, Import function that allows the user to create a new grid definition matching that in the import file when importing gridded data - Improved performance and reduced memory requirements importing grids greater than 5000x5000 rowsxcolumns - Fixed a bug that prevented the log editor from previewing the log smoothing results - Fixed a bug that caused grid contour lines to disappear if the grid bounds was set to the same parameter as that being contoured - Fixed a bug that prevented autosizing of contour line text labels when exporting contour lines to DXF files in world coordinates. - Fixed a bug that prevented the log calculation routine from working in Hungarian (eastern european) versions of Windows 2000 - Fixed a bug that caused double redrawing of the log window screen. - Fixed a bug that caused a warning that plot size exceeds page size when objects on hidden layers exceeded the current printer page extents Version 2.3.51 May 22, 2002 - Added full borehole geology to the 3D Geo-Explorer. Simply set up a template HDR file with Interpretation Set 1 containing the geology, then check the 3D Geology option in the Data Source Menu, 3D tab. - Implemented new hardware key driver support - allows for USB based keys and new "White" parallel keys. Note: new VIEWLOG uses will now receive white hardware keys, although the old green keys are still fully supported. - Implemented network installation - allows the program to be run from a shared network drive. Version 2.3.24 April 11, 2002 - Redesigned many of the menus (including Layer and MapView menus) to use integrated toolbars - Added new dockable tool window functions, including: - New tabbed dockable window layout - drag one floating window on another and they can either "stack" or form a tabbed group (note that the outline preview changes to a tabbed rectangle when this option is selected). To un-tab, just click and drag the tab to a new part of the screen. - "Pin" docked windows to the edge or bottom of the main window. Window opens when the mouse "hovers" over the tab - Applies to: Map View, Layer, Parameter Browser, Project Library and Legend, and Zoom windows - Note: The docking window positions are automatically saved when the program exits. - Added the new Map Legend Window. - Added the Project Library window. This window provides one-click access to any element in the Project. - Changed the Cross Section options window so that it can now be docked. This allows instant access to the cross section options, including the section shift and exaggeration options Performance Improvements: - Dramatically improved cross section regeneration when working with large grids (>2000x2000 cells) and projects with multiple grid definitions - Improved line contouring performance by 40% - Streamlined cross section polyline selection. In addition to the previous method to select a polyline for a cross section, plan view cross section lines are automatically selected if: 1. A single polyline is already selected when the Cross Section button is clicked, or; 2. The user is already drawing a polyline when the cross section button is clicked. - Fixed a bug which caused the Borehole Database floating window to appear incorrectly on screen - Fixed a bug in setting the initial default settings for the Modflow projects Version 2.3.14 Mar 18, 2002 - Added additional toolbar buttons and interface components - Improved cross section drawing performance with large (> 2000 x 2000 cells) grids and projects containing multiple grid definitions - Redesign of the 3D Geoexplorer user controls. Added three new navigation modes (rotate, translate and normal view) in addition to the fly mode. For complete details and access to the control panel press the Help button in the 3D window. Version 2.3.2 Feb 22, 2002 - Added support for dockable toolwindows (including the Layer Menu, Parameter Browser Menu, Map View Menu and Borehole Database Attributes window) - Fixed a bug in the pageview background color display. - Optimizated drawing of gridded data- improved screen performance by over 80 percent - Eliminated map screen repainting when overlapping windows moved. Version 2.2.94 Jan 24, 2002 Numerous additions and changes have been implemented. - Added functions to sort the order of the map views - Added a new map text keyword called ActiveMapViewNumber. This can be used in the auto legends, in conjunction with the keyword ActiveMapViewName to indicate a figure number in the printed report. - Extended the Viewport definition functions - Improved the viewport and vert exaggeration settings in the map scale setup menu - Added direct control of vertical exaggeration to the Page Setup menu - Fixed a bug with large thick polylines under Windows 98 - Reorganized the map menu - Added the File Project Menu items - Added the Project Properties menu - User can now optionally define a default lsm and db file -Fixed a bug in the Export as xyz polyline – now works from both plan and section, also exports all selected polylines Version 2.2.36 June 18, 2001 -Test release (Includes updates of functions that are not yet available to general users) Version 2.2.34 June 6, 2001 - Added the new Edit Database Table option to the Log Editor. This allows direct editing of the database contents. This function allows editing of complex, multi-field tables which are non-updateable by VIEWLOG (see the following paragraph for more details). In addition, the new menu streamlines data input because well name and parameter information is automatically entered as new records are added. This form can be accessed from either the Edit menu, or by right clicking on the log and choosing Edit Database table. (The Point Edit function provides similar functionality, but only edits the data presently opened into VIEWLOG memory.) - Added additional functionality to the save log to database functions. Previously, connections to tables containing unused, or extra fields ("complex tables") could only be accessed in read-only mode. This is because the additional data in the extra fields could not be preserved when major editing changes to the other fields were saved. VIEWLOG now checks for extra, non-null field data, and provides the user with additional options for saving the edited data back into the database. Note: direct editing of the database is best performed using the Edit Database Table function mentioned above. - Added the "Search Log Database/Directory First" option to the Log Database Connection Setup menu. This option simplifies the management of multiple VIEWLOG projects. When checked, VIEWLOG automatically first checks for files and database information in the directory containing the master database table. New projects can be created by copying database and template information from one directory to another, and then checking this option when configuring the new master database table linkage. (The Log Database Connection Setup menu is accessed by choosing File, Open Log Database, and then clicking the Configure Default Database button.) - Added the File, Save as Template HDR file menu item to the log editor. This function is identical to the Create Template HDR file options in the Open Log Database menu, yet is easier to access. - Fixed a bug which caused multi-page log prints to be spooled as separate print jobs when page headers were turned on. Only one print job is now created. This makes printing to a file, such as Adobe Acrobat PDF files, much simpler.  Version 2.2.32 May 31, 2001 New Feature: - Dynamic Section Shifting!  Cross sections can now be dynamically shifted (translated perpendicular to the main orientation of the section line). This provides a very effective method to investigate the surfaces in your geologic model. For example, using the new scroll bar in the Cross Section Options dialog box, an east-west section can be dynamically shifted 100 m north. The section is shifted and re-drawn in real-time, as the scroll bar is adjusted! As the section is shifted, the geologic model is sliced along the new section line, and appropriate boreholes projected onto that new section.  Dynamic Section Notes: - Any irregular multi-segment section line can be shifted.  - The shift direction is always perpendicular to a line drawn between the first and last point of the section.  - Use the Map X,Y position, displayed on the status line as the mouse is moved, to identify the map position of objects on the shifted section.  - Polygons and embedded bitmaps added to the section are not, or course, changed as the section is shifted. Only boreholes and data parameters that make up the geologic model are newly sliced and projected onto the new section.  - Warning: The position of a shifted section can be easily mistaken!! Either reset the shift distance to 0, or clearly note the shift distance on the legend when printing shifted sections.  - The current shift distance is saved when the cross section is saved. The section can be restored to its original position be entering a shift distance of 0. New 3-D GeoExplorer Features: - Filled (Tesselated) Polygons in the 3-D GeoExplorer! Filled map or cross section polygons are now fully rendered as filled polygons in 3-D mode. Note: If any of the polygon segments cross one another polygon will not be filled.  - Left/right translation in 3-D Fly-through mode. Press and hold the Ctrl key and left or right arrows to shift viewing position left or right. Press Shift+Ctrl+Left/Right arrow for faster translation. - Added auto (continuous) playback repeat for flightpaths in 3-D GeoExplorer.  - Dynamic speed control in the 3-D GeoExplorer. Speed controls now automatically adjust their sensitivity depending on the size of the geologic model.  - 3-D GeoExplorer Help Screen. The main key controls are now summarized in a help menu in the 3-D GeoExplorer.  Other Issues: New Feature: - Added log import support for SEG2 full waveform sonic data files (Century SG2 files). Choose the SEG2 format from the File Format drop down list in the Log Import menu.  Bug fix: - Fixed a bug that caused the wrong lithology symbol to be drawn at the bottom of multi-page log plots Version 2.2.26 May 16, 2001 - Bug Fix: Fixed a bug which caused a crash in the variogram analysis menu. - Bug fix: Fixed a bug that caused round off errors when projecting surfaces onto cross sections from grids with very small cell size. Round off errors only occurred when cells were less than 0.2 m in size and grid coordinates were expressed in UTM coordinates (eg, grid y origin at 48000000.2) Version 2.2.25 May 15, 2001 - Extended support for presentation of 2-D section gids in 3-D fly-through mode Cross sections containing data parameters gridded to the section are now fully displayed in 3-D mode. Two methods are available to enable the section gridded parameter in 3-D mode: Either open the section map file in VIEWLOG prior to entering 3-D , or set the Default display option in the Data Parameter Menu, Section View tab and then select the section line in map view prior to entering 3-D mode.  Version 2.2.24 May 15, 2001 - New feature: Added support for USGS Digital Raster Graphic (DRG) Files (Geo-referenced TIF image files) Geo-referenced TIF and BMP image files can now be placed in the map and section window. VIEWLOG automatically reads the associated TFW (also known as an ESRI World file) or BFW file associated with the TIF or BMP image file (The world file has the same name as the TIF file, but with the TFW extension). If such a file is found when placing an image on a map, the position information in the TFW file overrides the mouse-defined drag window (Note: the image can be re-positioned after the first placement). This option simplifies the loading of USGS Digital Raster Graphic (DRG) TIF files, which always include a TWF file. Note: 4-bit (16 color) USGS DRG files can be slow to draw because the 4-bit color lookup is a slow process. For better results, convert the 4-bit (16 color) image to a 8 bit (256 color) image using any common image editor.  Version 2.2.23 May 14, 2001 - Bug Fix: Fixed a problem with embedded bitmaps in the drawing and cross section editor. Under Windows 95 and 98, excessive zooming in on the image could cause it to not be displayed. The problem did not occur under Windows NT or 2000.  - Fix: When making geologic picks on cross section, the log image of the well now automatically updates when a pick is made even if the manual data reload option has been checked for that data source.  Version 2.2.19 May 9, 2001 - New Feature: New fault and discontinuity gridding functions. Previously, fault gridding was achieved by using the polygon gridding option, which allowed selected gridding of cells within a polygon using only data from within that polygon. The new fault gridding function allows handling of anytype of fault, including open fault traces, and sizor faults. To use fault gridding, simply select all fault traces on the map, then set the Data Parameter, Grid Tab, Extents option to Fault Gridding prior to clicking the Krige option. Surface segments within the fault offset zones (zones of displacement) with no data will be automatically linearly interpolated from surrounding cell values. Version 2.2.18 May 7, 2001 - New function: Extended support for the display of cross section information in the 3-D window. Until now, fence diagrams of the geologic model were created by pre-selecting polylines in the map plan view prior to entering 3-D view. While that method still works, with this new function, all cross sections open in drawing editor windows are automatically presented in 3-D view when the user enters 3D mode (Note: The cross section window must be set to World view). User drawn polylines and bitmap images (eg scanned seismic reflection data) embedded on section will be displayed in 3-D view.  - New function: Improved control over bitmap transparency in 3-D view. The 3D transparency of bitmaps, either in plan or cross section, can now be individually controlled in the Edit, Embedded Image Attributes dialog box. The transparency of plan view bitmaps (eg. airphotos) draped on ground surface can also still be controlled by adjusting the draped ground surface parameter. Transparency ranges from from 0.0 (opaque) to 1.0 (fully transparent).  - Added the xy plan view map position to the cross section status line. When drawing on section, VIEWLOG tracks the true 3-D position of the mouse and any object drawn on the section. The status line now displays the position of the mouse in 4 different ways, including: - Distance along section line - Vertical elevation - Map x position  - Map y position - Fixed a bug which limited cross section gridding to 2000 data points by defaulting to the Quick Krige option in the Data Parameter, Grid tab. Select Full Kriging to allow unlimited data points.  Version 2.2.17 May 4, 2001 - Fixed a scale label problem in the cross plotting menu. - Fixed a bug that caused a memory overflow when pasting into large (>60 MB) map files on Windows 95 and 98 (problem did not occur on WinNT) Version 2.2.14 April 20, 2001 - Test release (Includes updates of functions that are not yet available to general users) - Fixed a problem that caused a database upload warning when casting numeric well names into database fields defined as text.  Version 2.2.13 April 17, 2001 - Test release (Includes updates of functions that are not yet available to general users) Version 2.2.12 April 12, 2001 - Fixed a bug which caused an incomplete cross section to be generated when the section line partially overlaps the geologic model - Added Escape keypress check to the Kriging routines, allowing the user to interrupt the Kriging process by pressing the Escape key.  - Fixed a bug that caused a recoverable error when picking geologic units on cross section.  - Fixed a bug that caused a warning message when no data found in a well when regenerating sections  Version 2.2.8 Mar 30, 2001 - Added the new Master Borehole Database Table Menu to the Log Database Menu and Format, Header Menu. This can be used for adding new wells to the master database table or editing well header data for any particular well.  - Fixed a bug that prevented the Log Database Inventory functions from working correctly with Access 2000. - Added the new Log Track Background Color option to the Format, Page/Global Settings menu, Display Options tab. This allows the user to change the background color of the log data tracks. It can be used to enhance the log display on complex cross sections.  - Fixed a bug, introduced in version 2.2.2, that prevented the log templates from loading properly.  - Fixed a bug that caused the extended contacts from one interpretation set to appear in the track of a second interpretation when in Log Edit mode (bug did not occur in Log Preview mode). - Added new internal directory search options that help VIEWLOG find files when the log database is moved from one computer to another.  - Added new symbols to the NewVLSymbols.lsm library.  - Changed the symbol preview page to be more compact (change from 3 to 4 columns of symbols per page).  - Added the Read-only log database toggle buttons to the Database Connection Summary Menu (Click the DB Summary button in the Log Display, Database Tab). These buttons toggle all logs to or from read-only database access mode. - Added the Geotech.exe simple example database sample. This file contains a comprehensive set of sample files that illustrate all main VIEWLOG database, log editing, mapping, and cross section functions, but with a simple database containing only 3 wells. This file can be downloaded from the FTP site at ftp://ftp.viewlog.com/vlw2.  Version 2.2.2 Mar 25, 2001 - Fixed a bug that caused problems when two copies of the same HDR file were loaded in memory at the same time.  - Fixed a bug that caused a crash when importing shape file attributes with null field values.  Version 2.2.1 Mar 21, 2001 - Removed an extra warning message related to read-only data when saving logs.  - Fixed a bug in the log database inventory menu. - Code Change: one build and patch of VIEWLOG now runs on all operating systems (Win95 through Win2000).  Version 2.1.387 Mar 16, 2001 Map Editor Changes: - Added Lithology symbol fills to polylines, boxes and geologic units on plan view maps and cross sections. Any drawing object can now be filled with one or more lithology symbols. For example, enter "Silty Clay" to produce a fill pattern consisting of both symbols. All symbol types are supported, including bitmap fill patterns.  - Added two new data attributes to each map object: Generic Attribute and GeoName Attribute. These attributes can be read from the table portion of both Shape and MIF GIS files. The Edit, Advanced Select, Select by Attribute function can be used to select and manipulate objects with these attributes. Additional features using these attributes are planned.  - Fixed layer renaming problems in the Layer menu New Map Coordinate Transformations:---------------- Major Changes!!!---------------------- - Enhanced the Edit Transformation menu with new functions for converting between numerous map projections and coordinate systems, including: - NAD27/NAD83 (both USA and Canada) - US State Plane Coordinate systems (SPCS) - Different UTM ellipsoids and all UTM zones - MTM coordinates - Up to three transformations can be performed in one step. For example, to convert from UTM NAD27 to UTM NAD83 will involve three transformations internally through Lat/Long. - Transformations apply to all selected map objects, including borehole locations. Borehole location shifts are written back into the database. - Note: reference point files are required for NAD27/NAD83 conversion. Please contact us about obtaining those files.  Log Editor: - Fixed a bug which caused log scale errors in preview mode under Windows 2000 - Added the Edit in Grid option to the Right click menu popup in the Log Editor.  - Enhanced the log and interpretation data grid editor (point edit) to support additional functions, including Ctrl-C copy to clipboard as tab delimited data (suitable for pasting into Excel). - fixed the  Modflow Module: - Fixed a bug which caused the shortcut menu to load when right clicking while removing grid columns.  - Fixed a problem adding pumping wells to the MODFLOW well menu - Fixed a bug that caused keypad movement editing problems in the pumping well menu Contouring:  - Added new clipping options for color contouring (color clipping) Clipping can now be selectivly controlled on the bottom and top end of the contour range.  - Added the line contouring "Round to increment" option. When selected, contour lines appear at even multiples of the contour increment, and do not start until an even multiple of the increment past the contour start.  - Improved line contouring, particularly in handling "noise" around zero. - Significant performance improvements when contouring large grids (>500 by 500 cells) Well Attributes Selection:  Note: The well database table is displayed in a tabular "grid" window when the user right clicks on a borehole and selects the Attributes option (in both plan view or cross section view). Once the grid window is open, subsequent left clicks of the mouse force the grid window to update with information from that well.  - Right clicking to load attributes now always refreshes the attribute grid window with the correct database table.  - Once a grid window is open, the grid window correctly updates even if multiple wells from different datasources exactly overlap.  - The selected borehole now "flashes" when selected.  - When the Setup option is used in the grid window to change the datbase connection, the last selected well is now used as the default in the updated grid window.  - Added the "Show only Matching records" option to the "Other Database" option in the Database Link Setup Menu. This dramatically improves performance when linking to geology tables with multiple records per well.  Data Source Menu - Added the Logs tab. The Logs tab provides a summary of the template HDR file selection and editing options.  - Added "HDR Units" option to Data Source "logs" tab. If the data in the template HDR is in depth units, choose "Logs in Depth Units" to have VIEWLOG automatically shift the data to the correct elevation on cross sections.  - MAJOR Performance Improvement: The "Manual Data Reload" function in the Data Source, Source Tab, now causes the log images on cross section to be cached. Log drawing performance on section is up to 10 times faster. Click the Reload Now button to empty the image cache and redraw the boreholes from the database.  Lithology Symbol Editor ---------------- Major Changes!!!--------------------------- The Lithology symbol editor has undergone major revisions. Most significant is the fact that symbols can now also be used to fill polygons and geologic units on plan and section maps. Three symbol types are supported: Type 1 Simple vector symbols These symbols draw the fastest and allow for "stacked" symbols (eg. "Silty clay" formed by stacking the silty and clay symbols). These symbols also provide the best result when exporting lithology columns to Autocad DXF files (All symbol types work fine with metafiles and bitmap export formats.) The limitation of this format is that only one color and line thickness can be used, and filled polygon objects cannot be created.  Type 2 Image Files Type 2 symbols offer enormous flexibility. A lithology symbol can be created from any bitmap, metafile or VIEWLOG MAP file. Type 2 symbols can also be used to fill polygons on maps and sections, but draw slightly slower than Type 1 symbols. "Stacked" (eg. Silty clay) symbol combinations are supported for all Type 2 symbols except bitmaps. Advanced drawing objects, including filled polygons with individual control over line thickness, color and line type are fully supported when the Type 2 symbol is created from a VIEWLOG MAP file. Type 2 symbols are best used for creating complex, multi-color symbol patterns.  Type 3 Windows Fill Patterns Type 3 patterns are limited in appearance, but draw very quickly.  Changes include: - New Edit as Map button (For Type 1 vector symbols) This option allows the user to edit the vector symbol in the VIEWLOG MAP drawing editor. Full control over the drawing and editing process is available. When the map file is closed, the user will be prompted to save the symbol back as a Type 1 symbol (with potential loss of advanced formatting). The symbol can also be saved as a MAP file, for use as a Type 2 symbol.  - Import Button The Import button is used to manually convert a VIEWLOG Map file into a Type 1 symbol. When Import is selected a new symbol is created.  - Added the "Match whole word only" option. For example to distinguish between the keywords "sand" and "sandy", use the "Match whole word only" option on the "sand" symbol.  - New solid background color option. use the background color option to make symbols stand out. Symbols with a solid background should be drawn first, so that "stacking" is still supported (Use the Sequence Number option to control the symbol drawing sequence). Generally, solid backgrounds are used for the major litho classes, and modifier symbols are left transparent. For example, use a solid fill on the "Limestone", symbol, but leave the "Oolitic" symbol transparent so that "Oolitic Limestone" results in two symbols.  - Sequence Number (Seq. No.): This option allows the user to control the drawing sequence (order in which symbols are drawn). Symbols with a solid background should have a lower sequence number.  - Removed a limitation on the maximum number of lithology symbols - Fixed a bug when printing "View Library" litho summary page - Bug fixes in drawing system - Added the Unique litho class option: This option can be used to distinguish litho symbols when there is overlap in keywords. This option sorts the longer keywords first, changing the sequence numbers. The "Match whole word only" option can also be used to provide finer control over the keyword system.  Log Database Connectivity---------------- Major Streamlining Changes!!!--------------------------- The process of uploading large quantities of logs to a database has been significantly streamlined. The File, Open Log Database menu provides a gateway to this functionality.  Overview:  VIEWLOG/DB and /PRO are designed so that all log data and interpretation is stored in centralized relational database. The user creates a "Template HDR" file to control data selection and display formatting. One Template HDR file might be used for long format multi-page plots, another for single page summary reports, and a third for cross sections. The advantages include: - Data is not duplicated, vastly simplifying data management. - Only a few HDR files are needed. Data is selected and viewed using a consistent set of display parameters. Information selection and presentation can be changed simply by modifying the template. Switching from one template to another is quick and easy. New HDR files can be created from the templates simply by choosing "File, Save As", show individual well formatting be required (again, data is not duplicated, unless the user choose to "disconnect" from the database).  - Relational database processing functions (SQL) are available for name standardization, processing and data management. VIEWLOG now includes new database inventory functions to further provide insight into your log database.  Streamlining the Database Upload Process: -------------- Numerous functions have been added to VIEWLOG to simplify the database upload process. The goal is to allow the user to import logs (eg. from LAS files), review and correct them, and upload them into the database with as few steps as possible. This involves the following steps: 1. Setting default database connection parameters The first step is to set the default VIEWLOG database connection settings. This is performed by selecting File, Open Log Database and then clicking "Configure default database connection settings" button. Once in the Log Database Connection Setup dialog, the default connection properties are defined.  2. Importing Data The normal VIEWLOG file import functions are used for loading the log data. For example, one or more LAS files are imported, depth corrected and checked. No display formatting is necessary.  3. Connecting to the database Once the data is imported and checked, choose the File, Open Log Database menu, Manual Data Reload tab. Ensure that the well name is correct, then choose the "Connect File to DB" button to assign the default connection parameters. Once connected, choose the "Save Logs to DB" to save the logs to the database.  Note: It is not necessary to save the HDR file. The "Disconnect file from DB" option can, however, be used to disconnect from the database so that data is saved to the HDR file.  4. Extracting information from the database: Creating a Template HDR file.  Template HDR files are just like regular VIEWLOG files, except that each log and interpretation track is connected to the database.  ---------------------------------------------------------------------------------------------------- Version 2.1.368 Jan 23, 2001 - Fixed a bug importing non-standard (tab delimited) Mt.Sopris LAS files.  - Improved the application of default log database connection settings. (Added preview of Log Database Menu.) - Updated MODFLOW module to handle file names longer than 60 characters (now 256 characters max) - Fixed a bug which caused VLW1 files with to hang in print preview mode if log scales labels were not reset.  Version 2.1.361 Dec 11, 2000 - Fixed a bug that caused field type matching problems connecting a map to a database field for formatted log headers.  - Streamlined the database connection options when uploading many LAS files to the database. Default tables and upload parameters are now offered for each log, simplifying the upload process. More streamlining to come! Version 2.1.359 Nov 30, 2000 - Added an option to resample large Arcview grids during import. The option is available only if the Arcview grid does not match the grid definition of the currently selected data parameter. If more than one Arcview cell falls within the VIEWLOG cell the Arcview grid values will be averaged. - Increased the maximum grid definition size to 3000x3000 (rows x columns). Warning: This will result in grid files of 36 MB each if the max grid dimensions are used. Larger grids (!) are available on request.  - Extended the Parameter Calculator so that equations can now be applied to ALL selected polygons. Previously, only one polygon at a time could be processed. Note: Summation calculations total the result for all selected polygons. - Fixed a bug which prevented the import of multi-column interval logs (in ASCII or Lotus 123 format) - Fixed a bug with the new litho-based log fills when printing multi-page plots. Litho-fills would not appear after page 1. - Added support for LAS files in wrapped format.  Version 2.1.355 Nov 23, 2000 - Fixed a problem with printing very small sections (viewports) of very large scale maps on Windows 95. The problem was due to 16 bit limitations within certain Windows 95 print drivers. WinNT was not affected. Optimized the same routine to print small viewports approximately 10x faster through better data clipping. Version 2.1.354 Nov 21, 2000 - Added Drag and drop file opening. Simply drag and drop a map or hdr file onto the VIEWLOG title bar to open the file.  - Fixed a bug that caused map scale labels to appear very large - Added new Modflow Solver control menu - Added new Modflow Well Pumping menu - Added options to run MODFLOW, Modpath and Budprn directly from within VIEWLOG - Added function to automatically create the Modflow recharge file from Layer 1 recharge settings Log Editor: - Added the new Gradient Fill option to the Log Display Menu. This option color fills the log based on its response. - Added the new Litho Fill option to the Log Display Menu. This option fills the log with the color of the first lithology symbol within that interval.  - Added the new block filter option (both to the Edit Smooth and Display Smoothing options). Block smoothing makes the log appear like a histogram or interval log. - Modified the cross plotting system so that when symbols are drawn by litho set the symbol color is based on the lithology symbol color. In addition, only one common symbol is used for each lithology in the set (aggregration of data). - Fixed a bug in the litho symbol library settings. The last library loaded is now saved and correctly reloaded when the program restarts.  Version 2.1.341 - Fixed a bug in the display of geologic units in 3-D Geoexplorer. - Optimized the Data Parameter and Data Source menus so that they load database field lists 5x faster. This significantly speeds up the menu performance when working with tables with many (>40) fields.  - Changed the default MapView display of NEW data objects to OFF - The Release Tables button in the Data Parameter and Source Menus now release all tables associated with non-activated data objects - Fixed a scroll bar visibility problem with the Parameter Browser - Added the new Unit Name option to the cross section units option. The Unit Name appears in the Auto Legends. Version 2.1.327 Sept 28, 2000 - Added new keywords to the Insert Field option list in the Map Text menu. These field names return specific map parameters that can be embedded in the map text. The new keywords include: [MapScale] Returns the current map scale (ie. 1:5000). [MapScaleBar] Draws a full scale bar (page mode only). [VerticalExaggeration] Returns the vertical exaggeration of the cross section. [SectionOffsetDistance] Returns the Borehole search offset distance of the cross section. [MapUnits] Returns the world coordinates (metres, feet, km, or miles, as set in the View, Page Setup menu). [CurrentDate] Returns the current date (useful for tracking printed maps) [CurrentTime] Returns the current time (useful for tracking printed maps) - Expanded the [FullLegend] map text keyword function. Auto legends on cross sections now include color filled boxes to indicate the geologic units. - Added new water level symbols to the Data Parameter menu. When posting data parameters on cross sections these symbols (hollow and filled versions) can be used to indicate water levels in wells and monitors. They also will appear in the auto legends. - Added Data Parameter sorting control. The Up and Down arrow buttons in the Data Parameter List Tab can be used to sort and organize the data parameter list. Sorting parameters can be used to group related parameters (ie. geologic units) together in the list. The list order does not affect drawing order (drawing order is controlled by layer and activation), but it does control the order in which parameters appear in auto legends. - Optimized the Layer Menu refresh and close functions. This significantly improves Layer Menu performance when working with hundreds of layers in a map file.  - Added the Increase Polyline Node Count function to the Edit, Polyline Node Functions menu. This function resamples (through linear interpolation) the selected polylines so that additional nodes are added to the polyline. Nodes are added whenever two existing nodes are separated by more than a user-specified distance. Adding nodes improves the draping accuracy (appearance of polylines draped on ground surface) in the 3-D Geoexplorer function. Adding additional nodes can also improve the gridding results when gridding a data parameter from polylines. - Made the Map Layer menu resizeable. This menu can now be resized and moved off to one side of the screen for reference.  - Fixed a bug which resulted in log scale wraps when lotting nodata values contained within a unevenly sampled log.  Version 2.1.315  - Expanded the Data Parameter, Grid Tab, Import Grid function to automatically detect and read Arcinfo ASCII Grid files created on Unix file systems. ASCII files created on Unix systems do not have carriage returns at the end of each line (only a line feed). In addition, added support for Surfer Version 6.0 binary grid files, and fixed a bug when importing large surfer ASCII grids.
