Prepare MM Data Teledyne-Optech

This page describes how to prepare Teledyne-Optech mobile mapping resources for Orbit.
Using the Teledyne-Optech Orbit import template LMS prepared resources can be imported into Orbit

It is strongly recommended to read first Understand Mobile Mapping data in Orbit.

• File format : one ascii *.txt file
• File structure Rows : each trajectory timestamp is one record
• File structure Columns : space separated (char32), headers, with exact order and leading space as the example below
• Value “TIME” : GPS week time, seconds from last Sunday 00:00:00, decimal notation
• Value “Easting, Northing, Elevation”: any supported projected coordinate system can be used, but all mobile mapping resources should have the same crs

For each camera it is required to adjust the template camera calibration AttributeExpression values in the camera import Orbit Resource Description file.
Edit the template files prior to data import using a standard text editor (e.g. Notepad). Be meticulous regarding file structure and formatting.
