Cartography scale 1:500 of the urban areas

• 1:500 scale cartography of the urban areas of Biscay, from different campaigns (different years) The legend of each DXF/PDF document provides the date of the cartography. The WMTS must be combined with the cartographic grid service to know the year. The data are not subject to periodic updating processes. Each DXF file contains elevations generated using distinct altimetric reference frames. Therefore, these elevations should be considered relative to each individual sheet and not as absolute altimetry data. They are not aligned to a single geodetic reference frame.
