dc.descriptionAbstract. The survey and characterization of production systems, limited the scale of rural property, must take into account spatial information as a way to better ensure reliability of data collected. The objective of this work was, with satellite images, the accuracy of data declaratory of land use of agricultural settlement in Machadinho d'Oeste, RO, obtained during 20 years. Data from the cultivated area, and total forest acres in the lot were analyzed for approximately 460 lots georeferenced from 1986 to 2005 and comparing the data on the orbital declared by the producers was calculated to Estimated Relative Forecast (ERP) in percentage. The variables were submitted to the calculation of descriptive statistics and review spatializing using geostatistics. There was an increase in cultivated area and reduction of forest area with over time sampled, and spatial dependence was declared for the amount of cultivated area and forest (ha). The average values of the information contained in the questionnaire have to be lower than those obtained by satellite images, resulting in negative values mean the percentage of the Estimated Relative Forecast for all the years sampled. The highest level of accuracy of the information occurred for the florets area. The investigation of the accuracy of survey data declaratory of land use for the area sampled showed that the producer does not accurately scales with the area farmed, or area of your property, which validates this approach to finding the information declaratory with the help of image satellite.pt_BR
