UTM Rows and Zones Maps
With these key maps you can easily find out what UTM zone you are working from, I have been using it a lot because the LIDAR field work is usually always in a different place and it helps confirm that my system operator has been using the correct zone. I now have a UTM zone google Earth file witch I also use. Check it out here.
Simply click on the image below to enlarge it to expose all of the map, then find out where you are located and look for the zone and row that matches your area.
