Released by the IBGE in 2018, BC25_RJ and BC100_ES aimed at providing the society with a digital mapping, in the form of a continuous cartographic base for each state. Available in free formats (Shape File, GeoPackage and dump of the PostGis database) to be used in Geographic Information Systems, the 2018 versions were implemented according to the Technical Specifications for Structuring Vector Geospatial Data, version 2.1.3 (ET_EDGV v.2.1.3).
BC25_RJ version 2018: https://www.ibge.gov.br/en/geosciences/maps/continuous-cartographic-bases/18068-continuous-cartographic-bases-states.html
BC100_ES version 2018: https://www.ibge.gov.br/en/geosciences/maps/continuous-cartographic-bases/18068-continuous-cartographic-bases-states.html

The new release corresponds to a representation of the content mapped in 2018, with punctual amendments made since then - both of vectors and attributes -, though using an updated version of modeling, ET_EDGV v.3.0, maintaining the correspondence with current standards and norms of the Brazilian National Spatial Data Infrastructure (INDE), as well as with the modeling of the other cartographic bases released by the IBGE. More information on ET_EDGV v3.0: https://www.inde.gov.br/pdf/ET-EDGV_versao_3.0_2018_05_20.pdf

The bases released today are available by means of geo-services through the Interactive Geographic Platform, as well as through the IBGE portal:
BC25_RJ version 2018_edgv3.0: https://www.ibge.gov.br/en/geosciences/maps/continuous-cartographic-bases/18068-continuous-cartographic-bases-states.html
BC100_ES version 2018_edgv3.0: https://www.ibge.gov.br/en/geosciences/maps/continuous-cartographic-bases/18068-continuous-cartographic-bases-states.html
