Basic Spatial data of Andalusia -DERA- for medium scale is a set of geographic databases of different geometric nature (points, lines, polygons, raster images) related to Andalusia.
It comes in thematic sections (relief, hydrography, road networks, administrative divisions, etc.) permitting centralized access to updated information from very different origins. These databases have been treated to guarantee geometric coherence and spatial continuity for the whole region. Two blocks of spatial data contain contextual information about the world and the territories surrounding Andalusia.
DERA aims to facilitate researchers, professionals, teachers and technicians to build up their own maps or to use these data in complex spatial analysis for the generation of products and applications.
The information comes organized in different layers in shapefile (.shp) format in UTM zone 30 coordinates system and ETRS89 as datum.
