This research is based upon the soil study as an integrate environmental analysis regarded as the destination and use of Santa Cruz Governament suportted Region in order to grant the first environmental diagnosis at the western side of Rio de Janeiro.

The Soil Map of Rio de Janeiro Municipality (EMBRAPA, 1980) and The Planimetric Basis of Rio de Janeiro City (PLANRIO, 1977) were rasterized and directive vector added thus available only in analougue patterns at the scale of 1:50.000.

The Geographic Information System (GIS) was used to allow the spatial relationship among thematic geo-referenced areas, and Idrisi 2.0 for Windows was used for this implementation.

The environmental degradation and unbalance in such area is basically due to incompatible soil use.

In order to verify and define this soil usage a different soil map of urban occupation areas was developed as well as an industrial and agriculture chart with various soil differences with the need to have a better regulated and managed territory.
