The works were carried out in cooperation with the company Gispro from Szczecin, commissioned by the Head Office of Geodesy and Cartography as part of the task “Construction of 3D models of buildings” in the project of the Center for Spatial Analysis of Public Administration (Polish abbreviation: CAPAP). An important goal of the aforementioned project was to develop 3D models of buildings in the CityGML 2.0 standard at the level of detail of LoD 2.
In the 3rd part of the tender, 4 775 653 buildings located in five voivodeships: Świętokrzyskie, Opolskie, Silesia, Lesser Poland and Subcarpathia were designated for modeling. The models were made on the basis of building outlines from the BDOT10k database, data obtained from airborne laser scanning and numerical terrain model. Data for 137 counties are now available at geoportal.gov.pl. Their download service is completely free.
