WCs NW Temporal Digital Surface Model 50

The temporal digital surface model (tDom) corresponds to the difference between two time intersections of digital surface models (DOM). The tDom database is comprehensive and uses a DOM of lidar data (Airborne Laserscanning, ALS) for the tiles for which no historical image-based digital surface model (bDOM) is yet available. In the future, the tDom will only visualise the difference between the last two recording times of the bDOM. The displayed change notes apply per tile either for a 2-year period (bDOM-bDOM) or for a year period of up to 4 years (ALS-bDOM). The relevant information can be found in the material data query.
