This data category requires a high level national map. To satisfy this category, the following minimum criteria must be met:
- Scale of 1:250,000 (1 cm = 2.5km).
- Markings of national roads
- National borders
- Marking of streams, rivers, lakes, mountains.
- Updated at least once a year.
There is a machine-readable 1:250.000-scale vectorial map data suitable for ingestion in digital map-making systems (GIS), which includes administrative boundaries, water bodies, transportation infrastructure, energy and communication, etc. There are several other map products, at scales both greater and smaller that the above one. The licensing is unclear on the website of IBGE. As no clear license is available it has been evaluated as "not openly licensed". Also, proprietary formats are used to publish data. However, data is claimed to be public domain on Open Street Map, see http://lists.openstreetmap.org/pipermail/talk-br/2009-January/000029.html.
Evidence from the server where the files are hosted suggest that these maps are from 2013, in which case they are not being regularly updated (the criteria for it is to be updated at least once a year).
