                         aimed at to retrieve knowledge on the soil-relief relations 
                         through the evaluation of geomorphometric data and published soil 
                         maps. This was accomplished with SRTM data (Shuttle Radar 
                         Topography Mission), the local geomorphometric data base TOPODATA, 
                         and geomorphometric regional (non-local) variables, extracted 
                         through algorithms developed within this research. The 1:100,000 
                         soil survey map of S{\~a}o Carlos, S{\~a}o Paulo State, was used 
                         as the soil data source, together with its documentation. The 
                         methodological approach was based on the knowledge discovery 
                         process from maps, on the use of tools of Geographical Information 
                         Systems and imaging interpretation techniques. The main results of 
                         this work included algorithms for regional analysis of SRTM, the 
                         resulting regional geomorphometric data base of S{\~a}o Carlos, 
                         the geomorphometric description of the occurring soils and an 
                         indication of the geomorphometric variables potentially useful to 
                         separate their mapping units. Among the conclusions, it was found 
                         that the geomorphometric classes were related to two or three soil 
                         classes, according to the considered variable, at different 
                         mapping levels; the occurring soil classes at the more general 
                         level of classification, were distinguished by at least one 
                         geomorphometric variable; at the simples mapping units level, some 
                         taxonomic units were not separable. This research showed the 
                         evaluation of soil-relief relations at 1:100,000 scale to be 
                         possible through the integration of knowledge discovering approach 
                         with geoprocessing resources and SRTM data modeling.",
