As a combination of bachelor project / bachelor thesis.

Goal: Given OSM data in one of the usual formats (OSM-XML, pbf, o5m) and external elevation data from the SRTM project, annotate the OSM data with height information per node.

Requirements:

1. Obtaining the SRTM data for large areas is not trivial and requires a special tool (at least this is what we found).
2. You should write a tool that can be used from the command line.
3. The output format should be valid OSM.

Optional requirements:

1. Error correction for bridges and tunnels
2. Error correction for buildings (the height of a building should not include the building height, as would be the case in the SRTM satellite data)
