Divergence of information between official agents and land owners is quit frequent during the land Agrarian Reform process. Thus, in order to solve such questions, the time series analysis of satellite images has been used to subsidize the legal judicial phase of the land partion among several users. In the other hand, it is necessary to estabilish criteria to compare these images. This papper proposes a methodology to improve multitemporal analysis, composed by the following steps: a) acquisition of relative images to three different dates, b) normalization of the images by the use of the conversion of the grey levels for reflectance values, c) use of the Normalized for Difference Vegetation Index (NDVI) and d) comparative analysis of the dates integrated by means of the color composition of the NDVI images. That procedure allowed the comparison of different dates images. The visualization of the vegetation cover changes and landuse in an single image provided subsidies to the judicial phase of the land dispossession.
