How 'bout 2.4.4

2.4.3

What's new in 2.4.2

• experimental support for reading (and some writing) of GDAL raster maps
• point data are now also read from GRASS rasters, not only GRASS site lists
• libcsf is no longer packaged with gstat, but should be installed separately before compiling gstat. See links section where to get it.
• S/R library is now also available for S-Plus 6.0 and 6.1 for Windows, see here.

What's new in 2.4.0

• no temporary files are used anymore; if gstat must (e.g. for calling gnuplot using the system C-function on windows platform), it uses the file gstat.plt in the current working directory.
• removed user-choice of random number generator (-r command line option)
• removed several minor bugs
• allow processing multiple command files in a single process, e.g.

  gstat ex03.cmd
  gstat ex04.cmd
  gstat ex05.cmd
  

  can now be done as

  gstat ex03.cmd ex04.cmd ex05.cmd
  

• changed calls to asprintf into snprintf
• numerous source code changes, related to the development of a package/library for R/S-Plus

What's new in 2.3.8

What's new in 2.3.7

What's new in 2.3.6

set fit = 7;

What's new in 2.3.5

• Removed a bug, related to reading asciigrid mask maps. This bug was introduced when support for non-square grid cells was built into version 2.3.3.
• when writing multiple simulations to an ascii file, user-supplied format specification is now applied instead of a default format.

What's new in 2.3.4

• Additional upport for writing GRASS site lists (see grass support in gstat)

What's new in 2.3.3

• Support for reading GRASS site lists, and writing GRASS grid maps (see grass support in gstat)

What's new in 2.3.0

• simple mouse support for the interactive variogram modelling interface
• added new variogram fit weighting criterion: N(h)/(h*h) (with the advantage that it doesn't change when the model changes, so re-fitting gives the same fit all the time)
• added normal score transform, using:

  data(xx): 'file.dat', ..., ns='ns.dat'; # write norm. scores to ns.dat

  I did not include a back transform, because its non-trivial; read the GSLIB book or gstat-info threads about it.
• added data sampling:

  data(xx): 'file.dat', ..., prob=0.1; # sample randomly with P=0.1

  data(xx): 'file.dat', ..., every=10; # select every 10-th sample

  data(xx): 'file.dat', ..., every=10, offset=2; # select points 2, 12, 22, ....

• updated plotting of kriging weights (uses gnuplot); see manual at

  set plotweights = 10; set plotfile = 'file';

  (load this file into gnuplot for an impression of kriging weights plotting with plotweights=10)

• support PNG instead of GIF images, using

  gstat -e map2png

What's new in 2.1.0

• Interpolation with edges (given as polygons) -- code contributed by Konstantin Malakhanov and Steve Joyce. Read about it in the manual.
• replaced sk_mean with beta parameter vector, used in conjunction with X. This allows for simple kriging with a known, non-constant mean function. The phrase

  sk_mean = 5.3

  is now equivalent to

  beta = [ 5.3 ]

  However, the latter can be extended, e.g. by

  beta = [ 1.8, 3.7 ], X = 3

  to obtain a non-constant mean function.

• Addition of Surfer DSAA grid maps, bug fixes in the Idrisi grid map support. Read about it in the relevant section of the manual
• Faster code for multiple simulation generation; bug fixes for reproduction of data during Gaussian or indicator simulation
• Numerous code changes to enhance portability and improve maintainability
• added CYGWIN Win32 port
• allow seed values over INT_MAX by using

  set useed = 3057282920U;

• Native gstat variogram fitting uses Gauss-Newton (again). When weights N(h)/gamma(h)**2 are used, the weights are fixed during the fit and taken from the initial variogram (otherwise, the fit may not converge to a minimum weighted SSErr value). Levenberg-Marquardt is still obtained by Gnuplot fitting.
• accomodated the code for a Qt-based windows front end (in development): read the release notes and download the binary. The accomodation involved a complete rewrite of all I/O to stdin/stdout/stderr, by using runtime-modifiable wrapper functions, see set_gstat_error_handler() etc.
