Transform
Transform command applies a transformation to the coordinates of a trajectory. The transformation can be, for example, a change of the projections system or any other transformation defined in Coordinate transformations / Transformations category of TerraScan Settings.
You can find more detailed information about transformations in Chapter Coordinate Transformations.
To transform a trajectory:
1. (Optional) Select trajectory file(s) to transform.
2. Select Transform command from the Tools pulldown menu.
This opens the Transform Trajectories dialog:
3. Define settings and click OK.
The coordinates of the trajectory are changed. The modification is saved to the trajectory binary files in the active trajectory directory. An information dialog shows the number of effected trajectories.
SETTING |
EFFECT |
|---|---|
Apply to |
Trajectories to transform: •All trajectories - all trajectories in the list. •Selected only - selected trajectories only. |
Transform |
Type of transformation to apply: •Projection change - from one implemented projection system to another. •<name> - name of a transformation defined in Coordinate transformations / Transformations category of TerraScan Settings. |
Adjust heading |
If on, the software applies a meridian convergence correction to heading values. The correction is applied if there is a projection system change from WGS 84 longitude/latitude coordinates to another system. |
From system |
Source projection system. Click on the >> button to open the Browse for Projection System dialog. The dialog provides a search option for projection systems as well as a list of all implemented systems. In addition, any user-defined projection systems are included in the list. This is only active if Transform is set to Projection change. |
To system |
Target projection system. Click on the >> button to open the Browse for Projection System dialog. The dialog provides a search option for projection systems as well as a list of all implemented systems. In addition, any user-defined projection systems are included in the list. This is only active if Transform is set to Projection change. |
