[OSM-newbies] Triangulation using GPS w/ magnetic compass

[Kelly Jones]

If you have a GPS device w/ an accurate magnetic compass, you could
record the directions/angles to several far-away points from one
location, then move to another position, and record the new
directions/angles.

For each point, you know two angles and the length of the side between
them (ie, the distance between your two positions), and can use
triangulation to determine their points' latitude/longitude.

This would be a great way to map hard-to-reach locations.

People with panaromic city views could map dozens of streets in just a
few minutes.

Has anyone tried this approach?
