I am trying to learn how the grid numbers are determined for topo maps of Hawaii and Alaska. It seems that maybe I use the "minutes number" on the grid that is just lower than the minutes number on the map. For example, a map with 34'30" latitude and 20' longitude would have a grid number of E3. Can someone please tell me if this is correct? Thank you very much, Patty Grubaugh Patty Grubaugh <[log in to unmask]> --- End Forwarded Message ---
