Hi Tommy - love - Zermatt is nearly my second home - maps are a bit out though!!!
Map 1 is spot on; Map 2 you've centred on the Trockner Steg massive - it should be on the Stockhorn massive, so the runs on the north run down in the the Findelgletscher valley, not the Gornergletscher valley Map 3 you need to shift north a bit, so Trocknersteg is where you have put gornergrat Map 4 you've put Testa Grigia on the Matterhorn - so the map needs to move about 3 miles south east
good luck - getting the creative piste map artists to fit into the real world is a bit of a challenge !!
I've created a first try of the new draw tools in GE4 and I've tried to create all the ski trails in Zermatt in 3D hope you like it. If you have suggestions of comments please let me know.
