German Berlin Elevation Model
Introduction
The windPRO elevation model for Berlin is a digital terrain models (DTM) produced from open geodata from Berlin. The original data were produced and delivered by the Senatsverwaltung für Stadtentwicklung und Wohnen. The elevation model delivered with windPRO is at 5m resolution. The original model is available at a maximum resolution of 1m, 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 5m data made available by EMD represents the data status of December 2019.
Dataset Overview
- Spatial Coverage: Berlin
- Resolution: 5m (in windPRO)
- Data-type: Digital Terrain Model (DTM)
- Coordinate system
- Horizontal: ETRS89/UTM33 (EPSG 25833)
- Vertical: DHHN92 - Deutsches Haupthöhennetz 1992
- Version:
- Data were downloaded in December 2019.
- Data originates from aerial scans during years 2007-2008. Elevations were obtained by photogrammetry.
- Accuracy:
- Vertical: For the 1m resolution tiles accuracy is stated in tile-metadata to be 0.15m-0.30m
- Vertical: For the 2m resolution tiles accuracy is stated in tile-metadata to be 0.20m-0.50m
- Horizontal: Not specified
Availability from within WindPRO
The data are available directly from within windPRO in 5-meter grid resolution. Please note that for the 5-meter grid - the downloaded area is limited to 10 km x 10 km to keep the files at a usable size. The data within the elevation object may be extended with coarser data if a bigger area if needed. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose to height contour lines)
- Elevation Grid Object
Usage Notes
- Download and processing time is in the order of (a few) minutes for the high-resolution dataset (5m grid) - so please be patient! Due to the large amounts of high-resolution elevation data and the tile-based storage system, you will experience that downloading the data for a site may last a few minutes. If this is a problem for you, please consider downloading 'smaller' areas.
