Right. I believe this what the National Weather Service does for their radar maps. They're using a polar projection from the location of each station. Points 100 miles north, south, east or west will all fall in a perfect circle around the center of the map.

- Animats 12y agoThere's much to be said for that. We used that for automatic driving, using the starting point of the trip as the pole. This works well for trips of moderate length. GPS coordinates in Earth-centered, earth-fixed form (a vector from the center of the earth, which what you really get out of GPS) map easily to this form.
