Discrete Imagery

This page describes the import of Discrete (referential) Imagery. Three Discrete Imagery Variations are made based on the import of this image type, EXIF, TXT, and Random. Read the required structure for template types below.

Use the corresponding Orbit Import Template to import the described original data.
It is recommend to read first Orbit Mapping Resource.

• Image type: planar images
• Image orientation: Center pixel is orientation reference.
• File format: One *.jpg file for each image containing EXIF headers.
• Folder structure: All image files in a single folder.

Position and orientation, if available, from EXIF tags:

• X : TAG_LONGITUDE or TAG_LONGITUDE_REF
• Y : TAG_LATITUDE or TAG_LATITUDE_REF
• Z : TAG_ALTITUDE or TAG_ALTITUDE_REF
• Orientation : TAG_IMG_DIRECTION or TAG_TRACK.

• Image type : planar images.
• Image resolution : Any.
• File format : Each image is one *.jpg file.
• File name : Exactly as “Filename” value of photo position file, see below.
• Folder structure : All image files of one camera in one folder.

• File format : One ascii file (*.csv or *.txt file) per camera.
• File structure Rows : Each image is one record.
• File structure Columns : Tab separated (char9), headers, with exact order as the example below.
• Value of Filename : File name as on disk
• Value of Coordinates : Any supported coordinate system can be used, Long/Lat order for geographical coordinates, decimal notation
