====== Midas ======

This page describes the original Midas oblique mapping resources for Orbit import. 

Use the corresponding [[234:desktop_ext:mapping:manage_import:templates|Orbit Import Template]] to import the described original data. \\
It is recommend to read first [[234:technology:3d_mapping:about_resources|]].

===== Imagery =====

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

=== Image files ===

  * Files : *.jpg files, each oblique image is one jpg 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 [[234:technology:core:crs|supported projected coordinate system]] can be used, but all imported oblique resources should have the same crs.

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<1,2,3,4,5>/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.
