Merge from GPS and INS

Merge from GPS and INS command creates a trajectory binary file for TerraPhoto from separate GPS and INS files. The GPS file contains time stamps and coordinates for the trajectory positions, while the INS file includes time stamps and orientation angle values for the same trajectory positions. The software combines the two input files using the time stamp.

The GPS and INS files are usually text files. The format of the files can be defined in Trajectory formats of TerraPhoto Settings.

To create a trajectory from GPS and INS files:

1. Select Merge from GPS and INS command from the File pulldown menu.

This opens the GPS positions files dialog, a standard dialog for opening files.

2. Open the file that contains the positional information.

This opens the INS attitude files dialog, a standard dialog for opening files.

3. Open the file that contains the attitude information.

The Import trajectories dialog opens. See Import files for a description of the settings in the dialog.

4. Define settings and click OK.

The software combines the two input files and creates the binary trajectory file in the active trajectory directory.
