Least Squares Coordinate Transformations |
Perform least squares coordinate transformations on your data as well as
transforming between map projections.

| Where in the World is Your Data? |
 LISCAD
provides the easy answer when performing least squares coordinate transformations on your
survey and civil engineering projects.
Coordinate transformation parameters are computed by
manually entering point coordinates or by directly
selecting the points from the screen for both source and
destination coordinate systems.
Select either Conformal, Semi Affine, Unscaled or Affine in either 2D or 3D.
Individual weighting can be assigned to points plus the ability to easily
include or exclude selected points make it quick to calculate the
transformation parameters. A full report of these parameters can then be
generated.
The least squares coordinate transformations module also gives you the ability to transform your database onto and
between any of the following map projection types: Transverse Mercator (includes UTM), Lambert Conformal Conic, Double Stereographic, Oblique Mercator, NAD27
Transverse Mercator, NAD27 Lambert Conformal Conic, New Zealand and Swiss
map projections.
In civil engineering surveying the LISCAD 3D coordinate transformations
module is ideal for comparing as-built structures to
their design specifications.
