avroair Posted April 25, 2005 Share Posted April 25, 2005 Hey fellow cachers, I need some help plotting a couple of coordinates and figuring out bearings and distances. I have no software that can do that has anyone got a suggestion or can help me out with it? e-mail me. Link to comment
+Blaidd-Drwg Posted April 25, 2005 Share Posted April 25, 2005 One technique, and this is only one would be to convert the two locations to UTM and then plot them on a sheet of graphing paper. Then use a protractor to determine the azimuth from point to point. The answer would be in Grid northing, so it would then need to be adjusted the appropriate amount for the area being measured. A second technique, which is a variation of the first is to use a topo map to mark the two locations on. For a reference line, use the nearest grid line (from the marginal information). Draw it on your map. Again, the answers would be expressed in grid north. Yet a third technique would be to use Easy GPS. It's been awhile since I used it, but I seem to remember that it would express a direction and distance between two points. I don't remember what the azimuth reference was though. Link to comment

+Berjr1 Posted April 25, 2005 Share Posted April 25, 2005 Depending on your gps unit you may be able to do it on it as well, I have no problems doing it on my Garmin, Vista and my 60cs Link to comment
+The Leprechauns Posted April 25, 2005 Share Posted April 25, 2005 Try this site: Distance and Bearing Calculations Between Two Sets of Coordinates (FCC) USA This site forces the user to enter coordinates in Degrees/Minutes/Seconds format. I find this other site to be a bit more friendly, because I can enter decimal minutes in the minutes box (leaving the seconds box blank), consistent with the format used here at gc.com. Avro, if you need to visualize your waypoints on a map or aerial photo, feel free to make use of the terraserver viewer at geocachingadmin.com. Link to comment

avroair Posted April 26, 2005 Author Share Posted April 26, 2005 Great! Thankyou guys. If I had enlisted fellow cachers near me they would have been on to my tricks. Link to comment
