Brazilian Geodetic System
It consists of a group of stations (marks) on the land, implanted and maintained by IBGE. Their position serves as a precise reference for several engineering projects – construction of roads, bridges, barrages, etc – mapping, geophysics, scientific researches, among others.
Municipal, Topographic and Geographic Mapping
It encompasses the topographic charts and the maps derived from them – of Brazil, its regions, states and municipalities – which constitute the bases upon which surveys are done and their results are presented, as a homogeneous and integrated approach of the national territory. IBGE has produced the topographic mapping of Brazil in a systematic way, on standardized scales (lower than 1:25:000), according to the degree of development installed or projected on the territory.
It shows the evolution of the political and administrative division of the regional and sector divisions of the territory, surrounding and representing the legal areas and operating bases for statistical and geographic surveys.
Environment and Natural Resources
It is responsible for mappings, studies and researches of themes related to the physical aspects (relief, soil, climate, geology) and biological aspects (fauna and flora). It promotes the characterization and the evaluation of environmental conditions and the impacts generated by the intervention of man, which affect the environmental balance and the quality of life of the population.
Territory regionalization is done based on information obtained from spatial analyses, which produce territory samples on different scales, for example, geographic microregions. Geographic data are applied in the survey and dissemination of statistics and in the formulation and monitoring of public policies. Thematic summaries are present in the production of material at regional and national levels, such as the National Atlas of Brazil.
