Geoportal.gov.pl is the access point for Poland's national spatial data infrastructure, operated by the Head Office of Geodesy and Cartography (GUGiK). It provides orthophotos, digital elevation and surface models, lidar point clouds, cadastral references, and topographic databases.
Poland opened much of this data for free use, available through downloads and a broad set of WMS/WMTS services. Geoportal is the authoritative source for precise Polish base mapping, complementing the dane.gov.pl open data catalog.
