Temporal Digital Surface Model 50 NW

The temporal digital surface model (tDOM) corresponds to the difference between two time sections of digital surface models (DOM). The tDOM database is comprehensive and uses a DOM from lidar data (airborne laser scanning, ALS) for the tiles for which no historical image-based digital surface model (bDOM) is available. In the future, the tDOM will only visualize the difference between the last two recording times of the bDOM. The changes shown are valid for each tile either for a 2-year period (bDOM-bDOM) or for a yearly period of up to 4 years (ALS-bDOM). The relevant information can be found in the factual data query.
