Switzerland Elevation Model
Introduction
The Switzerland (Swiss) Elevation Model is a digital terrain model (Digitales Geländemodell, DGM) produced by SwissTopo - the Swiss Bundesamt for Landestopografie. The dataset is an accurate digital terrain model developed as a part of a 6-year data-collection process. Two Swiss elevation models are delivered with windPRO: one at 5m resolution and one at 20m resolution. The original models are available at maximum resolution of 0.5m and 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 October 2021.
Dataset Overview
- Spatial Coverage: Switzerland
- Resolution: 5m and 20 m in windPRO (original data in 0.5m and 2.0m grid resolution)
- Data-type: Digital Terrain Model (DTM)
- Coordinate system: Swiss coordinate system (LV95 LN02) - EPSG xxxx
- Version: Data download in October 2021
- Accuracy:
- The accuracy depends on the data-source. The following statement on accurcy is given as a one-sigma estimate for all 3 dimensions (see more at the links below):
- LiDAR: Newest data: 0.3m, Other data (below 2000m agl): 0.5m
- Elevations derived from stereo-correlation (above 2000m agl): 1.0-3.0m
- Manually corrected data (single points, edge-lines and areas): 0.1m - 1.0m
Availability from within WindPRO
The data are available directly from within windPRO in 10-meter resolution. The data can be accessed from the online-services in the following objects:
- Line Object (with purpose to height contour lines)
- Elevation Grid Object
