Using lat-lon coordinates from map to gps
Hi,
I have an old sea map (1967) which is using lat-lon coordinates.
What I need to do be able to read and type the coordinates I see on
the map to my gps and find that place. The problem is that I 1.
dont know how to read the map correctly 2. don^t know what grid system the map is using
....3. so I can use which?? system on my gps settings.
Pls help I have been reading articles in the inet about earth lat-lon and still can^t do it.
I can scan and send you the map if needed

Ignore the red line and 2 dots on the map. Lets say that I want the coordinates for my eTrex Hc Carmin
for the end of the land between latitude 3825-3826 and longtitude 503-504. My gps Position format is set to hddd mm.mmm´ and the map datum to WGS 84.
The position for that point given by the gps is
N 34 34,274`
E 033 01,824´
I don^t understand why is like that. Should^t it be sthg different?

Check the edges of the map. That should have the information you need, in what's called the "legend". If you can, post what what you can that might be useful, or scan the legend (not the whole map itself), and post that.
