====== Prepare Aerial Data Leica RCD30 ====== 

This page describes aerial nadir data from Leica RCD30 medium format aerial camera. \\
Using the corresponding template from [[180:desktop_ext:mobile_mapping:manage_import:templates]] the described resources can be [[180:desktop_ext:mobile_mapping:manage_import:index|imported into Orbit]].

It is **strongly recommend** to read first [[180:technology:3d_mapping:about_resources|]].

===== Nadir Images =====

=== Image files ===

  * Image type : Undistorted (corrected distortion and Central Principal Point) planar images.
  * File format : Each image is one *.jpg file.
  * File name : Exactly as in image positions file, see below.
  * Folder structure : All files in one folder.

===  Image Positions File ===

  * File format : One ascii file.
  * File structure Rows : each image is one record.
  * File structure Columns : space separated (char32), with exact order as the example below.
  * Value of Filename : File name as on disk, without file extension.
  * Value of Coordinates : any [[180:technology:core:crs|supported coordinate system]] can be used, Long/Lat order for geographical coordinates, decimal notation, without thousands separator.
  * Value of Angles "Omega;Phi;Kappa" : [[[[180:technology:3d_mapping:supported_resources|Omega, Phi, Kappa orientation angles]], degrees.

=== Camera calibration file ===

{{  :180:desktop_ext:mobile_mapping:manage_import:leica_rcd30_calibration.png?nolink&400|}}

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. 

=====  Point Cloud  =====

  * File format : One or more *.las files.
  * File structure : Las version 1.2.
 
===== Orthomosaic ======

  * File format : Any [[180:technology:supported_formats:index| supported image data format]].

The ortho is not a part of the UAS Mapping Run, it can be added separately to the Map view. \\
Convert the Orthomosaic file into *.omi format for enhanced performance.
