The Set Units button allows
you to select the reported units of measurement for the map. This affects the
map scale/bar and the Measure tool. Once you select the Set Units
button a dialog box appears at the bottom of the map page. You have a choice of
feet, miles, meters and kilometers. For the City of Mesquite the default is set
to feet. After you have selected your choice, click on Set Units to
activate the setting.
