Information Systems store detailed information on land resources, so that these can be accessed, combined, and analyzed for several purposes from different points of view. In Brazil, the information produced in soil surveys has not been efficiently made available, due to the great volume, complexity, and little standardization. Thus, with the objective of enabling the storage, manipulation, and disposal of information on Brazilian soils, the SigSolos System was developed. SigSolos was structured to allow the storage of information originated from different sources, levels, and scales of soil surveys, on well-known underlying soil concepts. The entity "Work" was established as the central entity of the system, reducing the need for compatibilization and standardizations in the data acquisition, due to the different sources and levels of Brazilian soil surveys. The first stage of SigSolos was concluded, and version 1.0 is now available for data storage. By now, some information on Brazilian soils can already be accessed at Iniciativa Solos.br, directly on the internet website Embrapa Solos.
