UTM Grids

The UTM grid overlays are useful to interpolate one decimal place beyond the grid interval on the map. For example on a 1:24,000 scale USGS topo map the UTM grid lines are 1000m apart. The overlay will show 100m increments.

Grids like this work best for determining the coordinates of a mark on the map. To plot a point onto your map use a UTM Box tool that is open in the center.
