The IBGE launches today (06/28) the 2018 version of the continuous vector cartographic base of the state of Rio de Janeiro on scale 1:25,000 - BC25_RJ. In that new version, the major classes of the Transportation System were updated. The base is available in digital format, to be used in different Geographic Information Systems, and can be accessed here.

This cartographic base, whose first published version dates from 2017, was produced in partnership with the State Department of the Environment of Rio de Janeiro (SEA-RJ) and allows, among other applications, the territorial planning of the municipalities, especially for the elaboration of municipal master plans.

Its applications in the area of ​​environmental management include planning of Conservation Units, delimitation of Permanent Preservation Areas (PPA), river basin studies, basic environmental recovery projects, as well as positioning analyses of projects submitted to environmental licensing. It is worth mentioning the importance of this cartographic base for Gravitational Mass Movement and Flood Susceptibility Mapping, in the scope of the National Plan for Risk Management and Response to Natural Disasters, is also highlighted.

The BC25_RJ - version 2018 was updated from orbital images (RapidEye and Sentinel-2), orthomosaics from aerophotogrammetric coverage provided by the Metropolitan Chamber of Rio de Janeiro, and data from other partner institutions, such as DNIT and DER/RJ, allowing the updating of the main classes of the Transportation System category. Among the updated elements are the federal and state highways, bridges, tunnels, viaducts and express lanes, such as the "Arco Metropolitano", "Transolímpica", "Transcarioca", "Transoeste" and "Transoceânica".

The BC25-RJ is available for free (shapefile, geopackage and dump of PostGis) to be used in Geographic Information Systems, being compatible with different software for reading geospatial data. The new base follows version 2.1.3 of the Technical Specifications for Structuring of Vector Geospatial Data, including, in addition to the transportation system, the other 12 categories of information provided in the ET-EDGV, which are: relief; hydrography; vegetation; reference points; localities; limits; economic structure; energy and communications; water supply and basic sanitation; health and social services; education and culture; and public administration. This product can also be accessed on the INDE portal; its metadata are available in the INDE and IBGE metadata catalogs.
