Import Openstreet data and terrain into Blender for free

Sometimes a client will ask to place their project on the real context, so he can have a better understanding of the project relationship to it's location So we will need to add that context to our ArchViz model in Blender. There are add-ons to import open-street data and terrain into Blender but there is a more cost efficient way to do that. I made a small video to show that.
I hope it's useful to somebody.
