3D Line intersection on digital elevation model

by Benji Sancho   Last Updated July 02, 2018 13:22 PM

I use QGis, Python and OGR/Gdal libraries.

I have two WGS 84 points with elevation that define a 3D line, for example [8.11, 47.3, 800] and [8.08, 47.2, 400].

I have a tif file representing an WGS 84 Elevation Model.

A want the [x,y,h] coordinate of the intersection between Elevation Model and this line.

How do I programmatically achieve this with gdal/ogr/python/qgis libraries?

cheers Benji.
