2D Helmert
transformation
Compass rule
Transit rule
TraversePRO
step-by-step
The TraversePRO methods include 2D helmert transformation, compass rule and
transit rule.
A helmert transformation is calculated based on two control points. These must be
the start point and the end, or closing , station. Shift, rotation and scale factor will
be computed and applied to the traverse.
Starting a traverse without an initial backsight measurement will automatically result
in a helmert transformation.
The coordinate misclosure will be distributed with respect to the length of the
traverse legs. The compass rule assumes that the biggest error comes from the
longest traverse observations. This method is suitable when the precision of the
angles and distances are approximately equal.
The coordinate misclosure will be distributed with respect to the coordinate changes
in Easting and Northing. Use this method if the angles were measured with a higher
precision than the distances.
1. Start and configure TraversePRO.
2. Enter station data.
3. Select starting method.
4. Measure a backsight point or go directly to step 5.
5. Measure a foresight point.
6. Repeat for the number of sets.
7. Move to the next station.
