This site is a demo to show Digital Height Model (DHM) of Switzerland in VR using the free DHM25/200m geodata of swisstopo. The data is 2x resampled, so using a 400m grid, using the median value in the original data.

Description

• Red line is the center of LV03 reference frame, old observatory in Bern.
• Blue lines are cities, Zurich, Basel, Geneva and Lugano.
• Rotation animation is around the center point (red line).
• There is a white-to-red color gradient to show heights, changing at every 600m.
• The scale is 1:10.000, so 1m in real VR space corresponds to 10km in real-life.

Technical Information

• This is a pure javascript frontend application with no backend.
• The VR 3D environment in frontend (web pages) is coded using A-Frame web framework.
• The points are rendered using a custom A-Frame component using BufferedGeometry and Points of three.js.
• The original data has around 1.4M points, since it is 2x resampled, there are around 365K points displayed on this demo.
• This app is hosted at Netlify and tested on Oculus Quest.
• I use Glitch during development, and export it to Github and when merged to master this is deployed to Netlify.
