I guess there are several tools for creating and manipulating terrain meshes out of map info ( I know nothing about maps and GIS and you name it). But, learning about all of this GIS technology feels a bit overhelming for this “one time” need for a mesh of an industrial area in the link below.
So my Q is: Can someone provide with a straight-forward instruction of what tools to use and how to configure it to retreive data and produce a (optionally textured) mesh of the following area? (If data is available, also a rough reconstruction of the buildings, but I can also do that part manually)
The part I want is roughly the follwoing (this is a industrial area, a steelworks, in northern Sweden):
