====== Prepare Oblique Data Cicade ======

This page describes how to prepare Cicade P65 oblique resources for Orbit. \\
Using the Cicade P65 [[180:desktop_ext:oblique_mapping:manage_import:templates|Orbit import templates]] prepared P65 resources can be [[180:desktop_ext:oblique_mapping:manage_import:index|imported into Orbit]].

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

===== Imagery =====

=== Image files ===

  * Files : *.ecw files, each oblique image is one ecw image file.
  * Naming : exactly as described in photo position file (see below, first column)

=== 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 : comma separated (char44), headers, with exact order as the example below.
  * Structure of file name : file name as on disk, with file extension.
  * 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 ===

For every camera it is required to review and adjust the default Orbit template camera calibrations, prior to the import. \\
<Orbit installation directory>/program/ext/obliques/project/template/<template_name>/planar<1,2,3,4>/import/import_locations.ord
===== 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.
