cator projection.
UTM’s are marked on USGS topographic charts.
This system divides the Earth into 60 zones, each
approximately 6 degrees wide in longitude. Their
unit of measure is in meters. For example, 15 N
means that the position shown to the right of the
“N” is in grid 15, and it’s north of the equator.
