Prepare MM Data Leica

This page describes Leica Pegasus BackPack and Mobile Mapping resources for Orbit.
Using the according Orbit Import Templates the described resources can be imported into Orbit.

It is strongly recommend to read first Concepts of Mobile Mapping and UAS data in Orbit.

The camera calibration parameters must be entered before Create Run, the 1st step of the Import Run procedure.
To facilitate import, your specific camera calibration values can be registered inside the Orbit template to avoid entering these values at import each time. Contact Orbit Support if assistance is needed.
