I'm working on a project for which I need data from different sources. I got satelite images from the Sentinel mission which are already in the appropriate spatial reference when dowloaded, in my case UTM26. My elevation model is from the ArcticDEM project and all downloadable files are using "Stereographic_North_Pole", independently from the location. I'm having trouble changing this to UTM26. My research suggest that "project" is the tool I need but this one does not let me chose my elevation data (.tif).
I'm pretty sure the answer is easy but I was not able to find a solution to this.
