Prepare Oblique Data Midas - Aerodata

This page describes how to prepare Aerodata Midas oblique resources for Orbit.
Using the Aerodata-Midas Orbit import templates prepared Midas resources can be imported into Orbit.

It is strongly recommend to read first Understand Oblique data in Orbit.

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

• 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 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.

• 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.
