Millionth Scale Map

The Brazilian Digital Cartographic Base on the Millionth Scale – bCIMd – is a cartographic product of IBGE. It portrays the current situation of the territory in the 1:1.000.000 scale through a vector representation of the lines which border reference cartographic elements, grouped into categories of information, and belong to the 46 sheets of the International map of the world on the millionth scale - CIM.

Its elaboration used as a reference the photomasks which originated the third updated edition of Millionth Scale Maps (1999), from which all the elements represented were extracted.

The production steps in Intergraph MGE and Geomedia environments encompassed the following processes: automatic conversion (raster process), semi-automatic vectorization and edition of the files which correspond to the sheets, joining of groups of sheets, consolidation of polygons representing elements of area (lakes, islands, Federation Units, etc.), topological validation, incorporation of semantic attributes and conversion to other formats for the sake of information dissemination.

Among its several applications, the map can be mainly used for the control of government plans and programs due to the wide view it provides of the territory, which can be suitable for monitoring and inspection activities. It is also a basic input for the World Aeronautical Chart (WAC) and for the Global Mapping Project.

The bCIMd may function as a geospatial component of both a National Planning System and a National Institutional Security System. The national infrastructure of transportation, energy, water, telecommunication, among others, can also make use of the integrated base in order to store and update information.

The bCIMd can also generate state and regional maps and maps for the composition of the National and School Atlas. It can be used as a base for the thematic representation of statistical data, such as those relative to the population distribution and the systematization of natural resources and environmental research.
