This paper presents the advantages of using the topology in a GIS project. The study was conducted on two watershed with mainly agricultural uses. We presented a model for creating the topology designed to monitoring the soils in the basins studied. In the present application, we qualify the graphical objects as soil units on the map. After the topology there was possible the grouping in thematic layers depending on their type and on many other information from the attribute-type database (erodability, humus content, texture, structure, pH etc.). Topological relations were created through an own program in Fortran language under Windows). The topological structure of spatial database in this GIS project is under Geo-Graph software. The existence of topology also brings another major advantage of the project: facilitates the creation of key links between databases, the important step towards the query.
