FIGURE 9.6 UTM with GPS. A handheld Global Positioning System (GPS) receiver is set to display the Universal Transverse Mercator

(UTM) grid and coordinate system called North American Datum 1927 ( NAD27 ), same as the map grid in FIGURE 9.8 . When operated at
point X , it displays its exact location as a zone and designator letter (18S) plus an easting and northing. Most hand-held GPS devices use
the World Geodetic System of 1984 ( WGS84 ) instead of NAD27 . Be sure your grid system is the same as that of any map on which you may
plot the GPS coordinates. Refer to the text for explanation.
