If you have your own DTM, it can be used to (partially) replace the DEM generated by the Tygron Platform:
How to import terrain height data:
- Create a DTM in GeoTIFF format
- Go to the Current Situation tab, hover over the Terrain button and click Select Elevation GeoTIFF
- In the panel that pops up click on Import new GeoTIFFs
- Locate the GeoTIFF on your harddrive and select Open
- After the GeoTIFF is uploaded and shown in the list, select apply.
- Your original DTM is replaced by the GeoTIFF where the GeoTIFF data overlapped with the project area.
Notes
- This operation is considered irreversible. Changes to the elevation model overwrite the terrain heights data directly. It is advised to create a new version if you ever want to revert back to the original elevation model.
- It is possible to select multiple GeoTIFFs and then clicking on Apply to apply them at once.
- If you want to partially replace the original DEM, create a DTM with nodata values where the original DEM should be used.
- The effected change is a single operation, not a permanent connection. After performing this operation, if new versions of the GeoTIFFs are uploaded, the Project's elevation model is not modified automatically.
