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.

• File : one ascii Track_*.asciitrj file.
• File structure Rows : Each trajectory timestamp is one record.
• File structure Columns : Semicolon separated (char59), headers, with exact order as the example below.
• Value of Timestamps “TIME” : GPS Absolute time or GPS Week time, decimal notation.
• Value of Coordinates : any supported coordinate system can be used, Long/Lat order for geographical coordinates, decimal notation, without thousands separator.

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.
