Polish Cadastral Parcel Boundary Polygon (GUGiK ULDK)

gugikuldk/parcel-boundary

The boundary polygon of a Polish cadastral parcel (dzialka ewidencyjna) as WKT in WGS 84 (longitude latitude), from its full identifier (for example 146518_8.0110.31/3). A parcel border is typically a few hundred to a few thousand characters; one over 100,000 characters is left out and flagged. An identifier that does not exist returns found false. Data from the Polish national geodesy office GUGiK (ULDK), passed through and served by Eden Engine; not an official GUGiK product.
