I am having an issue with the CRS of a given Aster DEM. I have downloaded a Aster DEM from www.oziexplorer3.com which comes with the EPSG:4326 - WGS 84 as the CRS.

This is a DEM from Gabon, and all the other data I have for the project I am working on has the CRS defined as EPSG:32632 - WGS 84 / UTM zone 32N.

I have to create some contours from the DEM in order to use them in another software for the elevation definition of a water network. When I open the DEM and SHPs I have in QGis they perfectly overlap (although they have different CRS) and so do the contours I extract from the DEM.

But then, when I import the contours into the other software, because they have different CRS, they do not overlap and so I can't use the newly created contours in order to define the water network's elevations... and if I change the CRS in QGis (for the DEM or for the contours) they do not overlap even in QGIS...

Is there a solution for this problem? Thank you very much!!

PS - please know that I am quite inexperienced with GIS softwares, but you might already noticed that...
