Topographic Mapping – Products
Digital Topographic Map Collection
Digital cartographic bases on scales 1:50,000, 1:100,000, 1:250,000, 1:1,000,000 and 1:5,000,000, representing natural and artificial features, grouped by information categories: hypsography, hydrography, localities, road system, limits, sites and edifications, reference points and vegetation.
These bases are being converted to a digital format, and structured for the use in Geographic Information Systems – GIS, by IBGE and partner public organizations at federal, state and municipal levels.
The files were obtained by means of automatic digitization via scanner. They can be provided as raster (RLE and TIFF format) or vector structures (DGN, DXF and ARCINFO format) with a protection system and are subject to scale conversion.
