Maintenance History for GS+ Version 5



Version 5.3.2 (posted 1 September 2002)

  1. Fixed problem whereby fonts on graph axis titles were not always changeable.

 

Version 5.3.1 (posted 12 January 2002)

  1. New graphics font library substantially improves font resolution on 3d graphs.
  2. Fixed problem with temporary files not properly deleting (in Win98 systems caused system hangs and .par file read problems).
  3. Improved efficiency of data imports and semivariance calculations by a factor >4.
  4. Fixed problem with Cokriging output to non-GS+ formats that caused some output files to be unreadable by some GIS programs.
  5. Fixed various minor problems such as coloration on some controls.
  6. Added capability of changing graph background panels, legend panels, and line colors, patterns, and thicknesses. Also allow graphs to be boxed.
  7. Fixed problem of some graph details not being persistent across file saves.

 

Version 5.1.7 (posted 6 June 2001)

  1. Provided ability to make column (field) assignments from the data import window.

 

Version 5.1.6 (posted 8 May 2001)

  1. In the worksheet window, row numbers are now visible for rows 1000+ after pasting more than 1000 records at a time into the worksheet.
  2. Polygon masks now work properly for inverse distance weighting interpolation.
  3. Temporary files now assigned unique temporary file names, all with .tmp extensions to avoid situations where network protocols disallow deletions of temporary files in the Windows directory.
  4. Map files now read correctly when using regional settings that substitute commas for periods as decimal placeholders.
  5. In variogram model window, when canceling from Co input box the original Co value is now restored, as is the case for other input boxes.
  6. Calculation of covariate variogram sometimes would use the active step defined for the primary variate variogram instead of the covariate's active step. Now always uses correct step.

 

Version 5.1.5 (posted 20 February 2001)

  1. Fixed problem whereby map legends would sometimes be incomplete and maps would sometimes lack a complete level.
  2. .In anisotropic variogram maps, resolved problem of graph details sometimes not being retained, and with unpredictable program crash with very large data sets.
  3. In map Define Contour dialog, resolved problem with contour levels sometimes not being saved successfully.

 

Version 5.1.4 (posted 10 February 2001)

  1. Improved variogram curve-fitting routine with new starting values for interpolations. To change starting point manually, in the Variogram Model window the values that appear in text boxes are now used for beginning values when the Refit button is pressed.
  2. Added warning for when a user attempts to import a text file with decimal placeholder when Windows Regional Setting is for comma placeholders.

 

Version 5.1.3 (posted 3 February 2001)

  1. Resolved a problem with spreadsheet imports for users who have their Windows Regional Settings set to use commas for decimal placeholders (rather than periods). This sometimes resulted in imported values being expanded by several orders of magnitude (e.g. 3,14159 might be imported as 314159,00).
  2. Resolved problem with reading .par files for users who have their Windows Regional Settings set to use commas for decimal placeholders (rather than periods). With this problem the GS+ version number was reported as 50102 rather than 5.1.2., thereby prematurely halting the reading of some files saved with version 5.1.2.
  3. All temporary files created by GS+ are now properly deleted when the program closes. Temporary files are created in the application directory and have a filename extension of .tmp.

 

Version 5.1.2 (posted 19 December 2000)

  1. In the Interpolation Window's Uniform Grid dialog, a bug that sometimes kept the y-axis grid interval from being edited has been fixed.
  2. The efficiency of file reads for very large .par files has been improved.
