M for Map.
I love geography and Maps. If I see a map I have to study it. Old maps are my favorite.
Before I go on holiday I use Google Earth to study roads, cities and so on.
I have two GPS’s. One Garmin Nüvi 660 for navigation in car, installed with a European road map.
At work, when I go in the woods and up in the mountains I use a Garmin 60CS with topographic maps.
This picture is a map from Trondheim and the area around.
This last one is a 3D picture of Mount Everest seen from the north. Google earth have a lot of interesting features.
