Unified hydrographic network of Andalusia, from the Numerical Topographic Base 1:25,000 (BTN25).
Description
The BCN25 is a two-dimensional and continuous GIS-oriented database covering the whole of Spain. This project contains the information of Andalusia represented in the National Topographic Map 1:25,000, which has been endowed with implicit topology, codes and names. It is organized in units that correspond to the sheets of the MTN25. The estimated positional accuracy is between 2.5 and 7.5 meters, depending on the type of entity.
