Introduction
The elevation model of the German Bundesland of Saxony-Anhalt (Sachsen-Anhalt) is a digital terrain model produced from data originally obtained from the open geodata of Saxony-Anhalt. It is produced and delivered by the Landesamtes für Vermessung und Geoinformation Sachsen-Anhalt (LVermGeo). Two elevation models are delivered with windPRO: one at 5m resolution and one at 20m resolution. The original models are available at a maximum resolution of 2m, however, the highest resolution model in windPRO version is resampled by EMD to obtain a slightly coarser resolution - 5m. This is done in order for the data to be operational for the larger domains needed in the context of wind farm analysis’ and wind flow modelling. The resampling is made based on 2m data using a bi-linear interpolation algorithm. Data made available by EMD represents the data status of January 2021.
Dataset Overview
- Spatial Coverage: Bundesland of Saxony-Anhalt
