Guest mikes451 Posted March 22, 2001 Share Posted March 22, 2001 It says your supposed to use HDDD MM.MM format. But my Garmin GPS 12 does not have that format the closest one is HDD MM.MMM is this OK to use? Quote Link to comment

Guest abeyoni Posted March 31, 2001 Share Posted March 31, 2001 quote:Originally posted by bacpac:I have a Garmin 12 and my format is the same. The trick it to convert the WGS-84 map datum to the map datum of your map. It is not a difficult trick, but one that is often overlooked. This is what I need to learn. To post a placed cache on the web site I need to show the WGS84 format. How do I get that info from my GPS unit? I've found cahces but only by using long/lat. Little help.

Guest bacpac Posted April 1, 2001 Share Posted April 1, 2001 To change the map datum or coordinate system with a Garmin 12 press the page button until the Main Menu screen appears. Select 'Setup Menu' option. Press ENTER and select 'Navigation'. Press ENTER. Scroll up to the Map Datum option and press ENTER. Scroll through the options with the arrow key. Select the appropriate map datum and press ENTER. The map datum should be listed on the particular map you are using. The USGS Topo Maps that I use are plotted with the NAD 27 datum. Do the same for the Positon Format option. My favorite position format it the UTM format that lists the coordinates in meters. Having the coodinates in a format that uses distance makes it easier for me. The UTM format is marked on USGS topo's as well. If you place a cache using a map datum other than WGS-84 make sure you select the WGS-84 datum before recording and posting your coordinates on this site. One of the best resources for begining GPSer's is http://joe.mchaffey.com Then newsgroup sci.geo.satelite-nav is a good resource as well. Good luck!
