Introduction
The digital elevation model for the German state of Mecklenburg-Vorpommern is derived from open geodata specific to this region, released during June 2024. The original model in 1m grid-resolution is provided by the Landesamtes für innere Verwaltung Mecklenburg-Vorpommern (LAiV). Three versions of the elevation model are included with windPRO, each with different grid resolutions: 1m, 5m, and 25m. While the original model offers a maximum resolution of 1m, the two other models are with slightly coarser resolutions of 5m and 25m. The two coarser versions are better suitable for larger domains, which are typically required for wind farm analyses and wind flow modelling. The 1m grid resolution data is specifically included with windPRO with the intension to be used for photomontage modelling. Please note that the data provided by EMD reflects the status as of July 2024. The Mecklenburg-Vorpommern elevation models in windPRO are based mainly based on aerial lidar-scans and optical stereo-imagery, with LAiV updating different areas within the region during a 10-year update-cycle (see image to the right).
Dataset Overview
- Spatial Coverage: Mecklenburg-Vorpommern
- Resolution: 1m, 5m and 25m (in windPRO)
- Data-type: Digital Terrain Model (DTM)
- Coordinate system
- Horizontal: ETRS89/UTM33 (EPSG 25833)
- Vertical: DHHN2016 (Normalhöhennull (NHN), Amsterdamer Pegel)
- Version: Data were downloaded in July 2024.
- Accuracy:
- Vertical: N/A
- Horizontal: N/A
- No-data value: N/A
Usage Notes
- Please be aware that the download and processing time for the high-resolution datasets (1m and 5m grid) can take several minutes. This is due to the large volume of high-resolution elevation data and the tile-based storage system, which contains about 6,500 individual data-tiles. As such, downloading data for a specific site may take some time. If this poses an issue, consider downloading data for smaller areas or opting for the coarser 25m resolution data.
- For the 1-meter grid, the downloadable area is restricted to a 5 km x 5 km region to maintain manageable file sizes. For the 5-meter grid, the downloadable area is limited to a 20 km x 20 km region. If necessary, the data within the elevation object can be supplemented with coarser data to cover a larger area. Please plan your downloads accordingly.
