About the publication - BDiA - web (en)
The IBGE´s Environmental Information Database - BDiA gathers thematic databases of natural resources of the national territory. These data were produced over the last 20 years, in four thematic areas: Geology, Geomorphology, Pedology and Vegetation.
Compatible with the 1:250,000 scale, the databases included in the BDiA were developed under the scope of SIVAM and Natural Resources Mapping projects from 1998 onwards. The methodologies and procedures used to develop these databases are an evolution of the methods developed along the RADAM/RADAMBRASIL Project, which surveyed the Brazilian non-marine natural resources in the 1:1,000,000 scale in the 1970s and 1980s. Part of the database of ad hoc information presented also came from RADAM/RADAMBRASIL.

The BDiAWeb portal is a platform to consult BDiA data aiming at interactively sharing the IBGE´s environmental information. In this first version, each theme presents 3 levels of caption, according to the visualization scale within the platform. The first two levels of caption were "rasterized" to improve the performance of the data browsing; on the other hand, the third level maintains the original vector format and the data can be accessed by clicking in each polygon. The 3 levels of caption are described in the information menu of each theme, as well as the additional layers belonging to each one.
New features will be constantly implemented and the data will be updated on a 2-year basis As of April 2019, the consultations made in the platform will be able to be exported.
The consultation in statistical grid, which allows to cross the data in the first two levels of caption of each theme, is in the test phase.
