Below is the detail information:

| DEVELOPED | 1996-2011 |
| AUTHOR | Edzer Pebesma<br /><br />Inst. for geoinformatics <br />University of Muenster<br />Weseler Str 253 <br />48151 Muenster, DE<br />[[mailto:edzer.pebesma@uni-muenster.de][edzer.pebesma@uni-muenster.de]] |
| PLATFORM | Windows & UNIX. Platforms running R |
| PURPOSE | Program, and R package, for uni- or multivariable geostatistical modelling, prediction and simulation. |
| FUNCTIONS | + variogram, cross variogram, covariogram or cross covariogram calculation; <br />+ modeling of nested models, interactively or non-interactively <br />+ pooled (within-class) variogram estimation <br />+ variogram maps <br /><br />+ ordinary kriging, simple kriging, multivariable universal kriging with arbitrary base functions <br />+ kriging with external drift <br />+ reading observations, prediction locations, and base function values for universal kriging or category numbers for stratified kriging <br />+ stratified universal kriging <br />+ conditional and unconditional Gaussian simulation <br />+ Indicator simulation for simple, categorical or cumulative indicators <br />+ block predictions for rectangular blocks or arbitrarily shaped blocks <br />+ Gaussian simulation of block averages conditioned on point observations <br /><br />+ concise, intuitive command language that allows batch processing and eases documentation <br />+ Map formats supported are PCRaster, Idrisi, Arc-Info/ArcView+SpatialAnalyst (gridascii and gridfloat), Grass, ER-Mapper, GMT, and SURFER . <br />+ writing maps with predictions, simulated values, error variances and error covariances <br />+ optionally ascii input and output (independence from GIS formats) |
| CODES | C codes are available from https://svn.52north.org/svn/geostatistics/, R version available from CRAN <br />windows binary for gstat stand-alone with support for csf gd (png) (gif) grass gdal gsl pdcurses and netcdf: see link below |
| TIP | Graphical user interface for Gstat have been developed: one within the PCRaster project, the other one for IDRISI. <br />The authors of GRASS also adopted Gstat as their geostatistical add-on module. <br /><br />Gstat has two mailing lists: one for announcements, and one for questions and discussions. |
