====== Prepare MM Data Optech ======

This page describes how to prepare Optech Lynx mobile mapping resources for Orbit. \\
Using the Optech [[110:mobile_mapping:desktop:mobile_mapping:manage:import:templates|Orbit import templates]] prepared Lynx resources can be [[110:mobile_mapping:desktop:mobile_mapping:manage:import:index|imported into Orbit]].

It is **strongly recommend** to read first [[110:mobile_mapping:about_mm_resources|]].

===== Trajectory =====

Currently no known Optech export.

===== Imagery =====

==== Panoramas ====

=== Image files ===

  * Image type : Ladybug 5 or Ladybug3, equirectangular panoramas
  * Image resolution : ratio 2x1, 8000x4000 advised for Ladybug 5, 5400x2700 for Ladybug 3
  * Files : *.jpg files, each image is one jpg file
  * File name : exactly as "Filename" value of photo position file, see below
  * Folder structure : all files in one folder

=== Image positions and orientations file ===

  * Files : one asccii *.txt file
  * Rows : each image is one record
  * Columns : tab separated (char9), headers, with exact order as the example below
  * Value "Filename" : file name as on disk, with file extension
  * Value "Latitude", "Longitude" : any [[110:technologies:crs:crs_orbit|supported projected coordinate system]] can be used, but all mobile mapping resources should have the same crs
