Gstat
Below is the detail information:| DEVELOPED | 1996-2011 |
| AUTHOR | Edzer Pebesma Inst. for geoinformatics University of Muenster Weseler Str 253 48151 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; + modeling of nested models, interactively or non-interactively + pooled (within-class) variogram estimation + variogram maps + ordinary kriging, simple kriging, multivariable universal kriging with arbitrary base functions + kriging with external drift + reading observations, prediction locations, and base function values for universal kriging or category numbers for stratified kriging + stratified universal kriging + conditional and unconditional Gaussian simulation + Indicator simulation for simple, categorical or cumulative indicators + block predictions for rectangular blocks or arbitrarily shaped blocks + Gaussian simulation of block averages conditioned on point observations + concise, intuitive command language that allows batch processing and eases documentation + Map formats supported are PCRaster, Idrisi, Arc-Info/ArcView+SpatialAnalyst (gridascii and gridfloat), Grass, ER-Mapper, GMT, and SURFER . + writing maps with predictions, simulated values, error variances and error covariances + 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 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. The authors of GRASS also adopted Gstat as their geostatistical add-on module. Gstat has two mailing lists: one for announcements, and one for questions and discussions. |
