The landforms are one of the main definers of the environmental units, so that its compartmentalization presents it self with close relation to the distribution of the other attributes of genesis of the landscape. The objective of this study is to establish a compartmentalization of the relief in the municipality of Toropi located in state of Rio Grande do Sul, with the use of cartographic bases in digital format associated with Geographic Information System, through automated methods and with the integration of morphometric variables. The analysis considered the following parameters: hypsometry, slope and slope amplitude. These classifications describe the different relief units and point out their main characteristics, identifying areas of greater or lesser fragility when associated to the lithological substrate. Theclassification using the Geographic Information System, with SRTM altimetric data, proved to be quite efficient, since it represents the characteristics observed in the field.
