Rotate

To rotate the selected points around a specific point:

  1. The buttons in the Select Points field allows you to select the points for rotation:
  2. Select the Rotation Point which is to be the center of rotation. This can be entered manually, selected from the map or from the list of the job points.
  3. Select the Rotation Method. This can be by entering a Rotation Angle or by entering the Old and New Azimuths.
  4. Click the Calc button to calculate new positions of the points. The results can be seen through the Edit Points dialog.

Note: During this transformation of selected points, original coordinates of the points measured with GNSS receiver will be replaced with new (transformed) coordinates. You will be prompted to confirm such overwriting for each GNSS measured point that is in your selection, with the following available options:
- overwrite this point only;
- skip this point;
- overwrite all;
- skip all.


Translate

To translate a group of points:

  1. Select the points for translation using the buttons in the Select Points field:
  2. In Translate By, select the method for translation. This can be by Coords/Pts or Az,Dist,Ht:
  3. Click the Calc button to calculate new positions of the points. The results can be seen through the Edit Points dialog.

Note: During this transformation of selected points, original coordinates of the points measured with a GNSS receiver will be replaced with new (transformed) coordinates. You will be prompted to confirm such overwriting for each GNSS measured point that is in your selection, with the following available options:
- overwrite this point only;
- skip this point;
- overwrite all;
- skip all.


Scale

To scale the distances of a range of points relative to a Base Point:

  1. Select the points for scaling using the buttons in the Select Points field:
  2. Select the Base Point that is the reference point for the scale transformation. This can be entered manually, selected from the map or from the list of the job points.
  3. Set the Scale Factor of the coordinate transformation as required.
  4. Select the Scale Heights check box if the height values should also be scaled.
  5. Click the Calc button to calculate new positions of the points. The results can be seen through the Edit Points dialog.

Note: During this transformation of selected points, original coordinates of the points measured with GNSS receiver will be replaced with new (transformed) coordinates. You will be prompted to confirm such overwriting for each GNSS measured point that is in your selection, with the following available options:
- overwrite this point only;
- skip this point;
- overwrite all;
- skip all.


2D Transformation

To perform two-dimensional transformation of point(s) from one coordinate system to other coordinate system:

  1. Create a list of point pairs used to calculate the transformation parameters. More...
  2. Select the points for 2D transformation and calculate the task. More...

2D Transform

The 2D Transform dialog allows you to edit a list of point pairs for use in calculating the transformation parameters between two coordinate systems:

Select Next to move to the next 2D Transform tab.


Point Pair Info

To select the pairs of points or coordinates to obtain transformation parameters:

  1. Select From Pt/From Crd to enter either the point or coordinates from which the parameters will be calculated.
  2. Select To Pt/To Crd to enter either the point or coordinates from which the parameters will be calculated.

2D Transform Parameters

The dialog displays the transformation parameters which will be applied to the set of points which needs transformation.

  1. Select the points for transformation using the buttons in the Select Points field:
  2. Click Back to return to the previous dialog.
  3. Click the Calc button to calculate new positions of the points. The results can be seen through the Edit Points dialog.
