 Powerful
Survey Calculations
 Record
all of your COGO entries with Batch and replay as desired.
Express 2002 includes a powerful set of COGO
functions. Our new Batch COGO capability is unmatched.
As a function of Active Drawing Technology, Batch COGO
allows you to build complex COGO calculations in a spreadsheet
and re-run them as necessary.
Express 2002 also includes command line COGO that you
can use at any time by simply typing "COGO"
at the prompt. You immediately enter a familiar style
of entry that prompts for point numbers, bearings, distances,
and solve points. Intersections are computed by leaving
unknowns blank, and letting the program automatically
determine what type of intersection you would like to
compute. Bearings, distances, point numbers can all
be picked off the screen by selecting point labels or
lines.
COGO commands are also available in a more graphical
format. If you select a line or arc on the screen with
no command running, you can immediately calculate new
points. Express 2002 also allows you to compute without
storing point numbers. The lines and arcs that you create
can be instantly coordinated and numbered at a later
time.
Helmerts Transformation.
With the Helmert’s Transformation, you
are able to rotate, shift and scale up to 5000 points
based upon a best fit solution using 2 to 500 pairs
of common coordinate points, all with the execution
of a single command! When more than two points are common
in each system, redundancy exists and a Least Squares
method is used to determine the optimum (best-fit) transformation
parameters.
Coordinate Transformations.
Use the coordinate transformation function to
easily transform your data from one system to another.
UTM, 3TM, SPC (NAD27, NAD83, HARN) and hundreds of others
are supported.
Other Tools.
A Proportioning function makes it easy to proportion
distances along arcs or curves, to create equal line
divisions and divisions based on ratios like dividing
a line into 2 segments, 1 segment at 2/3 of the overall
distance and the other at 1/3.
Radial Inversing can be used to create radial field
ties quickly and effectively. List the ties in a line
table with the click of a button.
