| Summary: | The objective of this study was the upgrade of soil mapping units defined in surveys published by the Radambrasil/ IBGE in 1983 and 1987, with the main focus on the clas - ses of soils. To accomplish this, data from representative soil profiles of those surveys were used to classify them in the current Brazilian Classification System. The mapping units which do not have representative profiles were updated based solely on the direct correlation between the denomination used in the old and current classification. This work has also updated the legend of the reconnaissance soil map. The layer of information related to
soil, in shape format, containing an attribute table with data regarding mapping units and the respective updated legends (taxonomy, symbols and colors) is currently available and
can be downloaded by the general public using the Geobases browser. A specific geographic interface for the partners of Geobases dedicated to soil studies has also been created.
This interface allows the analysis, acquisition and input of new data, which contributes to the non-duplication of efforts and financial resources on activities of surveying, registering and maintenance of geospatial database related to soils in the State
