Currently, the original line is converted to distance to the origin (possibly with a simplification) and altitudes are assigned. This was to prevent the theft of valuable DTM data. With OGD, this is no longer necessary.
1/ Assign an altitude z to an input line. Simply return the GeoJSON, KML, or GPX with the altitude corresponding to each point.
2/ As at present, return a distance. How to calculate distances with WGS1984 and pseudo-Mercator datum?
