Geological Map of Spain — IGME-CSIC OneGeology 1:1M geological vector data (CC-BY 4.0). 16,041 lithostratigraphic units covering the Iberian peninsula, Balearic and Canary Islands.
Geological vector data from the Instituto Geológico y Minero de España (IGME-CSIC), served via the OneGeology WFS at 1:1,000,000 scale. 16,041 polygons with English-language attributes (Erathem, System, Description, Symbol_S). Downloaded via paginated WFS GetFeature in 500-feature pages (33 pages total), with axis-order fix applied (WFS returns lat-lon despite GeoJSON spec). Tiled into Sentinel-2 MGRS T28-T31 (107 stored tiles, peninsular + Balearic + Canary Islands), stored as GeoPackage on s3://3bee-esabloom-satellite-assets/map_nat/ES_GEOLOGICAL_MAP/. Follows the ProtectedAreasReader pattern: each polygon is a separate area card with its own label, age, description, and tectonic zone.
