São José dos Campos: INPE, 2007. p. 1499-1506.c1506  aGeographical information systems are becoming a common information management and analysis tool used in a wide and growing range of application fields. The popularization of GIS techniques request the easy-to-use softwares. From among 12 freeware softwares evaluated, Hypercube (a freeware program produced by the US Army Corps of Engineers Topographic Engineering Center) was considered the most efficient to perform functions related to filter, warp, mosaic, reformat, calibrate, and combine multi and hyper-spectral imagery. FGIS, according with the same criteria, was considered the most efficient to perform shapefile editing programs, digitizer and GIS data query tool.  aremote sensing  aSensoriamento Remoto  aCBERS  aFGIS  aFree software  aHypercube  aImage processing  aProcessamento de imagens  aSoftwares gratuitos
