Cartography 1:5000, Bizkaia Topographic Base (BTB) 1:5000

The 1:5000 scale mapping or Bizkaia Topographic Base (BTB) is a set of topographic vector data. For its generation, it started from a 25 cm photogrammetric flight carried out by the Basque Government in the summer of 2021. The cartography has been made by photogrammetric restitution, updating the layers of the following topics: geographical names, transport, hydrography, relief, land cover, buildings and services and facilities. Information on the Foral Road Network from February 2022.
