%X The Digital Elevation Model (MDE) describes the configuration of the topography of the terrestrial surface, allowing to derive this product in contours, slope, direction of flow, drainage, slope exposure and solar energy incidence and guides the delimitation of watersheds. Different ways of obtaining models are proposed and MDE SRTM (Shuttle Radar Topography Mission) is widely used with applications in various regions of the world. In southern Amazonia, in the middle course of the Madeira River, the configuration of transition between natural formations of savanna vegetation and dense forest predominates. The canopy of dense vegetation associated with a relief with little altitudinal variation can create a canopy effect, reflecting the microwave radiation emitted by the Space Bus Endeavor, which mapped 80% of the planet''s surface in February 2000, influencing abrupt variations of Altitude recorded in the MDE-SRTM. GPS points associated to digitized coordinates of topographic charts were interpolated using the Kriging method and variogram adjustment for the KRIG MDE that represents this transition region between savanna and forest. The MDE SRTM and MDE KRIG are analyzed in this paper, and the main results show that the MDE SRTM distinguishes the two major vegetation (Dense Forest and Savannah) in shades of gray and by whole dimensions. The MDE KRIG presented better representation of the relief with respect to SRTM for the generation of contour lines and delimitation of the basin in this transition region between savannah and forest in tabular formation of sedimentary terraces.
