Using a UTM grid overlay tool

UTM Grid If you want to find your location with more precision than is available from the grid lines on the map, you will need a tool that is marked in finer divisions. One such tool is a grid overlay. The grid overlay is placed on the map with its edge aligned with the grid lines. Then the position of the mark can be determined using the tool's additional precision. Additional precision is available by either by "eyeballing" or by using a UTM Corner Ruler with finer markings. For many land navigation situations 100m precision is quite adequate.

 

 

 

The example shown here locates the Red Star Symbol to a precision of 100m. The 10,000m and 1,000m digits of the coordinate are taken from the map. Thus the coordinates 59 82 locate the 1,000 meter square containing the star. The grid overlay is placed over the grid and the 100m digit is determined. Remember to read the Easting followed by the Northing.

In 100m abbreviated format the coordinates of the Red Star Symbol are 597 821. UTM Example

 

The "pocket sized" UTM grid overlay shown here is available from MapTools.
