Continuous cartographic bases - Brazil

About the publication - Brazil - 1:250,000, version 2023

The Continuous Cartographic Base of Brazil at scale 1:250,000 (BC250) offers an overview of the territory and serves as a reference to support territorial planning, monitoring and management actions, enabling thematic mapping of the country's population, geology, vegetation, soils, natural and environmental resources, among other topics.

This new launch marks the 10th anniversary of the BC250 development, which has been updated every 2 years, since its first release in 2013.

The base was developed from satellite images covering the entire national territory, from data produced by other IBGE surveys and research and from data from partner bodies, which allowed the updating of several information contained in the version launched in 2021.

Among the improvements in this sixth version are topological quality control edits, completion of mandatory attributes according to data modeling, a major effort in adjusting the connectivity of the drainage section layer, to enable integrated visualization of the country's drainage network. In addition, some classes with non-homogeneous distribution in previous versions were complemented, such as signaling and cemetery.

As a whole, the product includes classes of 13 categories of information: Energy and Communications, Economic Structure, Hydrography, Borders and Locations, Relief, Transportation System, Transportation/Airport System, Transportation/Pipeline System, Transportation/Railway System, Transportation/Waterway System, Transportation/Road System, Base Classes of Topographic Mapping on Large Scales and Culture and Leisure.

This version also presents a new layer, called Name Index, where it is possible to locate, through their geographic coordinates, all the names of the features that make up the base, represented by dots.

The base is compatible with the precision requirements of the National Cartographic System (SCN) and adapted to the standards and norms of the National Spatial Data Infrastructure (INDE). The data is structured according to the conceptual model of the Technical Specifications for Structuring of Vector Geospatial Data, Version 3.0 (ET-EDGV 3.0).
