====== Prepare Oblique Data Ultracam Osprey ======

This page describes how to prepare Ultracam Osprey oblique resources for Orbit. \\
Using the Vexcel Ultracam  [[180:desktop_ext:oblique_mapping:manage_import:templates|Orbit import templates]] prepared resources can be [[180:desktop_ext:oblique_mapping:manage_import:index|imported into Orbit]].

Today the Ultracam Osprey Camera 1 should not be imported, skip the import step and continue from Camera 2.

===== Imagery =====

=== Image files ===

  * Files : *.tif files, each oblique image is one tif image file.
  * Naming : Exactly as the result of "Concat([Nr],[Filename_Suffix])", from the photoposition file bellow. 

=== Image positions and orientations files ===

  * File : one *.csv or *.txt file for each camera
  * Structure : Flat ascii text file
    * Rows : each image is one record
    * Columns : semicolumn separated (char59), headers, with exact order as the example below.
  * Structure of file name : Exactly as the result of "Concat([Nr],[Filename_Suffix])" from the example bellow.
  * Crs : Any [[180:technology:core:crs|supported projected coordinate system]] can be used, but all imported oblique resources should have the same crs.

=== Camera calibration ===

Principal_Distance = 123.009695
PPA_X = 6.842097
PPA_Y = 0.014417

===== DEM =====

=== Raster file ===

  * File : one *.tif file with corresponding *.tfw
  * Naming : free of choice
  * Crs : Any supported projected coordinate system can be used, but all imported oblique resources should have the same crs.
