====== Prepare Navvis M3 Data =====

This page describes the original Navvis M3 Trolley-V1 indoor mobile mapping resources for Orbit import. 

Use the corresponding [[211:desktop_ext:mapping:manage_import:templates|Orbit Import Template]] to import the described original data. \\
It is recommend to read first [[211:technology:3d_mapping:about_resources|]].

===== Panoramas =====

=== Image files ===

  * Image type : Equirectangular panoramas.
  * Image resolution : 8192x4096 pixels.
  * 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 *.csv or *.txt file.
  * File structure Rows : Each image is one record.
  * File structure Columns : Semicolon separated (char59), headers, with exact order as the example below.
  * Value "filename" :  File name as on disk, with file extension.
  * Value of "pano_pos" coordinates : Projected coordinates, local height, decimal notation, no thousands separator.

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

=== LiDAR files ===

  * File format : One or more [[211:technology:supported_formats:index|supported point cloud files]].
  * Value of Coordinates : Same references as Panorama Photo Positions, see above. 
By default, the NavVis software exports the pointclouds as .ply files. To transform a pointcloud in.ply format to an Orbit supported format, widely available free third party software can be used.
