I would like to use a Digital Terrain Model and Digital Surface Model of Latvia or the Riga region together with footprints of buildings in this area (with the information of heights of these buildings if the DSM is not available), to create a virtual 3D model of the area of interest containing DTM and 3D buildings.
There is a need to have:
- Open data of buildings’ footprints (from cadastral data or any other open dataset)
- Open data od Digital Terrain Model. The Digital Surface Model is suitable for defining the heights of buildings, if the information about the heights (or at least the number of storeys of buildings) is not available.
If you are interested in such a topic, feel free to join me at Baltic Open (Geo) Data Hackathon.
