Preliminary 3D measurement data NW

Every year, Geobasis NRW surveys 1/5 of the state area of ​​NRW using airborne laser scanning technology. The current survey area was flown between November 2021 and March 2022 and extends over the southern regions of North Rhine-Westphalia, which are particularly affected by the heavy rain events in July 2021. Preliminary 3D measurement data (v3DM) will be made available once for early provision of the data. The v3DM represent an interim result from the production process of the 3D measurement data and do not yet fully correspond to the quality standard of the official German surveying system.
