Codes for spatial data analyses

The purpose of this page is to provide you with information on add-on modules or free codes for spatial statistics that require other packages to run.

R codes

R is a free clone of S+. You can get more information about it at http://www.r-project.org/. R is growing so quickly that there is no way to keep this section exhaustive and up to date. I therefore can only invite the visitors to visit this two web sites dedicated to R for spatial statistics: "R Spatial Projects" - link is broken, will be checked soon - and the "CRAN task view: Analysis of Spatial Data".

Here below are indicated a few well known packages.

• ADE4 (analysis of lattice data, designed for ecological data-analysis)
• GeoR (2D Geostatistics & simulations)
• Gstat (2D Geostatistics & simulations)
• GeoXP 1.3 (Exploratory spatial data analysis)
• SPATSTAT (Point processing)

Matlab codes

• BMELib (3D Geostatistics, Bayesian Maximum Entropy)
• DACE (2D Geostatistics)
• EasyKrig (3D Geostatistics, Co-kriging)
• Matlab Kriging Toolbox (2D Geostatistics)
• Matlab Spatial Statistics Toolbox (various spatial autoregressions)
• mGstat (A geostatistical toolbox for Matlab)

F77 codes

• VISIM: GSLIB based F77 program for sequential Gaussian and direct sequential simulation with histogram reproduction

Other

• An ArcGIS 9.3.1 model for exploratory analysis of point data: GeoTechMoBuApp

USEFUL RESOURCES

• Source codes of a large number of algorithms presented in the journal Computers and Geosciences can be found online.
