Maps of Cross-border Areas

The 1: 50.000. cross-border maps are a collaborative project between the Institute of Statistics and Cartography of Andalusia, the National Geographical Institute and the Directorate-General for the Territory of Portugal, which have provided all the geographical information necessary for the integration of the data and enabled the Bajo Guadiana Map to be drawn up. The scope of the map includes the entire estuary of the river Guadiana in the districts of the West Litoral of Huelva, much of El Andévalo, the eastern part of El Algarve and the municipality of Mértola in El Alentejo. In a total of 16 municipalities in the three regions, an area of 2.900 Km2 divided into two leaves, Bajo Guadiana Norte and Bajo Guadiana Sur.
