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? -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology. We feel that resistance to new ideas and technology is unwise and ultimately futile. _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies
