Defining a map projection
Most map projections conform to a
standard type and will need to be
defined before being used for the
first time.
From the COORDSYS\ Type
Selection screen, open the
Projection list.
Press DEFLT (F5) to reveal all of the
available default projections and US
State Plane Zones.
Select NEW (F2) to enter a new
projection set.
Enter the name of your projection
and select the type of projection.
Although the majority of projections
are Transverse Mercator, UTM or
Lambert, a variety are available.
Input the parameters of your
projection, not forgetting to scroll
down the complete list and enter all
parameters.
Press CONT (F1) to continue.
The next step in the process is to
match the common points.
Points from the two systems with the
same point Id will be suggested for
matching by default.
If you do not wish to match two
points, highlight the point pair
concerned and press MATCH (F5).
This key is also used when
determining a 1-Step or a 2-Step
transformation and you wish to match
the points in height or position only.
To match a new coordinate pair,
press NEW (F2) and select the
WGS84 and local point to be
matched.
