World is split into 60, 6º degree zones
Seattle area is Zone 10N
Distorted above North 84º, and South 80º, not applied above these latitudes.
Smallest grid unit on USGS 1:24000 maps is 1 km. May be different on different scale maps!
Coordinates get larger going east (easting) from the zone meridian and larger going north (northing) from the equator.Universal Transverse Mercator (UTM)
Divide the distance between the coordinate to
the left of your point and the coordinate to the right of your point into tenths
This is hundreds of meters
But we can go finer, if we use a template
Warning - Photocopied map or map printed from “Topo” may have an odd scale
Example: 490120E 5315340N
Use template to determine position within the kilometer box.
