The concentration of large rural land properties by a few landholders is still very high in Brazil. In order to minimize this situation the government established at December 1999, the Portaria INCRA/P n° 558/1999, cancelling the whole issuing of land titles of properties with 10.000ha or more properties. A time of six months for land titling and registration was given, but after eighteen months, the greatest number of the properties were not regularized. This fact could appears like land unlawfull seizure. In this work it was used a GIS, software SPRING, for generate cadastral maps of rural properties at Tocantins State. The work allowed to conclude that the SPRING software is excellent in the production of cadastral maps for describing spatial information and individual parcels, as well as the fact that these maps are georeferenced. Thus SPRING could be a very important tool for the land reform.
