Management Zone Analyst (MZA)

This program is designed for the USDA (United States Departament of Agriculture) is a decision-aid for creating within-field management zones based on quantitative field information. It mathematically breaks up a field into natural clusters or zones based on the classification parameters and number of zones you specify.

GEOEAS

GEOEAS is a collection of interactive software tools for performing two-dimensional geostatistical analyses of spatially distributed data. The principal functions of the package are the production of grids and contour maps of interpolated (kriged) estimates from sample data. GEOEAS can produce data maps, univariate statistics, scatter plots/linear regression, and variogram computation and model fitting. (DOS and Windows)

SAGA 1.2

SAGA - short hand for "System for Automated Geoscientific Analyses" - is a free, hybrid, cross-platform GIS software. The heart of SAGA is it's C++ and thus object oriented Application Programming Interface (API), providing data object definitions and computational methods for raster, vector and tabular data. As a normal user, you will not get into touch with the API. But as an interested scientist or coder you will soon discover it's great flexibility.
