%X Due to the technological advancementes in the area of topographic data acquisition and the consequent reduction of costs in the acquisition of data through orbital remote sensing, the application of these products has been increasing in the most diverse areas of engineering, especially in roadway and railway infrastructure projects. Unlike other countries, where continous programs of cartographical updates and DSM and DTM acquisition take place aiming to support infrastructure projects, Brasil does not have any governmental initiatives in order to comply with market demands for medium and small scale topographical data. The present research aims to stablish an statistical comparison of altimetric data, as well as compare the earthmoving volumes and analyze the morphology of digital terrain models obtained through different data acquisition methods in an specific area of study and geometric project of a prototype railway. The altimetric data were collected through conventional topography, laser scanning and remote sensing (SRTM, TOPODATA, ASTER GDEM V2 e WorldDEM). Thus, a study was done on a 5.1km railway segment leading to the conception of both a horizontal and a vertical alignment, based on the design guidelines recommended by the standards of DNIT, as well as the terrain data framework analysis accordingly to the standards of cartographic accuracy.
