    The purpose of this work was to adapt the MicroLEIS - Land Evaluation Information System developed in Spain to the Brazilian Southeast conditions. Twelve (12) variables were considered, as follows: A - Relief Factor: 1) Slope; B - Soil Factor: 2) Effective depth, 3) Texture, 4) Stoniness, 5) Drainage, 6) Salinity; C - Erosion Factor: 7) Erodibility, 8) Slope, 9) Vegetation density, 10) Rainfall erosivity; D - Bioclimatic Deficiency Factor: 11) Frost, 12) Available water. For each of them, the control parameters were changed, according to conditions of the soils of the State of São Paulo.

    The SIAT is a specialist system for Land Evaluation derived from the MicroLEIS - Land Evaluation Information System developed in Spain. In its first version the 12 variables were adapted and adjusted for tropical conditions as well as the program structure and databank. In that time the field tests showed that the best results were obtained for scales near 1:100.000. In this second version the ranges for each variable were redefine and a communication interface with the GIS IDRISI was introduced, which allowed the exchange of data between the two programs.
