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.

Data Location


The new iGEO site provides full maps with 1:10000 resolution and clear open data terms.

However, this data is free for academic and research purposes, but sold for commercial purposes (e.g. companies). This is made clear in their FAQ (in Portuguese):

«A utilização da informação é gratuita para a Administração Pública e Academia, prevendo-se a cobrança de taxas justas para as empresas, com aplicação de descontos caso se tratem de entidades sem fins lucrativos.»
