increase positive in the north and east directions.

Note: The geodetic calculation engine and the Survey Pro coordinate

geometry engine are separate components. While the geodetic engine

can properly handle southwest grid systems, Survey Pro can only

operate on a northeast grid system. However, since a southwest grid

with a south azimuth is a mirror image of a northeast grid with a

north azimuth, Survey Pro can handle this configuration with the

following work around: You must set the

Azimuth Type

to North

Azimuth

on the Units

card of the Job, Settings screen. You then treat

north as south and east as west, and the coordinates will be correct

for a southwest grid and south azimuth zone.
