National Topographic Base

Three-dimensional multiscale database (1:2.000-1:25.000) with complete and continuous coverage for Spain. It contains topographic and thematic data that allow its exploitation by means of geographic information systems and the generation of cartographic products. It includes hydrographic information with network structure and IGN reference geographic information on transport and populations. It also integrates information on buildings and constructions from the national cadastres, information from the topographic bases produced by the Autonomous Communities and other official sources of the Public Administrations. The resolution of the data depends on the thematic treated, but it can be assured that globally the positional accuracy is better than 3 metres in X, Y, Z.
