Import Lynx Survey

Not UAV

Import Lynx Survey command reads information from a Lynx index file and creates a mission file, an image list, and (optional) camera files.

The index file is a text file that contains information about the survey, camera parameters, and images. The file is created by Optech software delivered with the Lynx system. The camera parameters for each camera of the system are converted into a TerraPhoto camera calibration file. The time and positional information for the images are converted into a TerraPhoto image list.

To import a Lynx survey index file:

1. Select Import Lynx Survey command from the Mission pulldown menu.

This opens the Import Lynx survey dialog, a standard dialog for opening files.

2. Select the index file and click Open.

The Import Lynx survey dialog opens:

import_lynx_survey

3. Define settings and click OK.

The mission file, an image list file, and possibly camera calibration files are created in the given directory. The camera files are named CAMERA1.CAL and CAMERA2.CAL.
