For the United States, two separate
horizontal control systems have been
developed by the Federal Government:
State Plane based on NAD 1927, and
State Plane based on NAD 1983. In the
US and for International use, the UTM
(Universal Transverse and Mercator
System) can be selected.

Zone: For State Plane projections, the
correct state zone for the job location
must be selected. For UTM, the
automatic zone option will automatically
use the correct UTM zone for the job
location, or a specific UTM zone can be
manually set. The manual option may be
applied to surveying on the border
between zones to force the program to
use a particular zone.

Use Alignment for Localization
(Transformation): This two dimensional
transformation option can either be by
Plane Similarity or Rigid Body methods.
Both methods use a best-fit least
squares transformation. The difference
is that the rigid body method does a
transformation with a translation and
rotation and without a scale. The plane
similarity does a rotation, translation and
scale. This option only applies when two
or more points are used in Localization
(transformation).
• One Point Alignment Azimuth: This option applies
to the rotation when using one point in Align Local
