Description

The “Saladas de Sástago-Bujaraloz” (41°23'N, 00°12'W) is a complex of 149 saline playa lakes and closed depressions located in the semiarid central Ebro Basin (Aragón region). The area is included in the Natura 2000 network, and 26 of these wetlands have been designated as RAMSAR Sites of International Importance since 2011. This protected wetland complex has been affected by the agricultural pressure (land division, farming, irrigation), which has led to the degradation of several wetlands. The data presented here belong to the research project by the grant PID2021-127170OB-I00 funded by 738 MCIN/AEI/10.13039/501100011033 and by “ERDF A way of making Europe”, and is a contribution to Andalusian Research Group P.A.I. RNM-328 and the project PIE202640E020. The reproduced USAF-B flight photography belongs to the Spanish Air Force Cartographic and Photographic Centre (CECAF). The compressed folder “Geomorphology_Sastago-Bujaraloz.zip” includes two vector datasets, i.e. the shape of polygons “2026_carto_bu_polygon” and the shape of polylines “2026_carto_bu_line”. We included the legend (.lyrx) for both shapes. The two geographic layers are projected in European Datum ETRS89/UTM zone 30N and include the components necessary for visualization in a Geographic Information System. The source of the geomorphological map is the stereoscopic photointerpretation of the USAF aerial photographs (1956-1957) at 1:33,000 scale. The document “notes.docx” includes the explanation the column header of the attribute table of the three shapefiles.
