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 that is developed as a part of a 6-year data-collection process.

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 downloaded 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
