Managing large spaces often requires appropriate data formats. Working on a large set should be efficient and possible in a variety of software. CityGML is an open standard for presenting virtual cities. This standard distinguishes several levels of model detail. Depending on the needs, they can present only the approximate shape of the building, the shape of the building with the mapped roof, or finally the building together with its small elements, including the interior.
Due to the creation of almost 5,000,000 buildings for the area of 1/3 of Poland’s area, we have experience that few domestic contractors can demonstrate. The technology we have developed enables us to produce large-scale models of this type in the LoD2 standard.
