The organization of a large number of farmers of information is a challenge faced by rural extension institutions and environmental inspection, generating delay in decision-making within the management and disseminating technologies. The database is presented as a useful tool and coupled with the use of a Geographic Information System, contribute to better organization, and consequent reduction of mistakes made in the surveys carried out by these institutions. The objective of this study was to develop a database with a sampling producers and rural properties in the arroio Cambaí watershed in Itaqui, RS, structuring an appropriate and efficient organization system that allows the storage, modification, access and dissemination of information on it contained. Questionnaires were developed and applied for the removal of technical information on the properties, geographic location, and contact the producers. After the information is structured in a geographic database using the QGIS software, combining satellite images used to effectively acreage surveys. In the satellite image analysis and polygons worked by CONAB were identified errors that can be easily corrected by a professional who has technical knowledge of the analyzed region. The geographic database contributed to display effectively cultivated areas with rice.
