MapTools.com is my go to source for map tools. It seems like every time I browse their site I turn up something new to try. I am also a big fan of the Delorme Atlas & Gazetteer (A&G) map booklets but I have always wished that I had the tools needed to really make the A&G maps work well with my GPS.
The UTM Coordinate System makes syncing maps and a GPS very easy but the A&G maps are not labeled for use with UTM so I needed to find an alternate way. I found that way with the latitude longitude coordinate system and the extensive selection of map rulers at MapTools.com. Delorme makes the A&G in a variety of different scales (15 in all) and MapTools.com makes a map ruler for each one of those scales.
These rulers allow you to, with some basic knowledge of the latitude longitude coordinate system and some practice, transfer points between your map and GPS unit with precision. The rulers also have distance scales in meter and mile scales. They are available individually or as a set of all 15 different scales used in the A&G series. These are some very handy tools to have in your navigation kit.
Check out the MapTools.com site for more information on the map rulers and other great navigation aids.
