                         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.",
