Gridding a Map

Using Tope Explorer! Colorado, overlay UTM grid lines. The program gives an option for size. I use 154 meters which is 500 feet on a 1:24,000 scale. Those that prefer tenths of a mile use 161 meters.

Then copy this map into Excel.

 Draw lines along the grid lines and then delete the map. After that,  group the lines. This process only has to be done once if you save the file and always use the same scale.

Rotate the gridlines the amount of variation. In this case, 8 degrees.

Then import the map without gridlines. Send the picture to the back and slide it so crossing lines are at the start.

Now you don't have to deal with variation because I have an easy to orient MN overlay.
