The Export Photo Package on the Sensor Tab will allow the user to export the photos on the retained photos layer with the associated camera calibration files. This tool facilitates the downstream import of images into third-party photogrammetric processing software.
Note: Images must have had the Update EXIF Tags run on them, either directly or through the Photo Processing option in the Geocoding
tool, before being able to run the Export Photo Package utility for a Cycle/Flight combination.
Important: Export Photo Package is not used when using the tightly integrated Agisoft Ortho Mapping or Ortho Mapping
tools. It is used when processing in other photogrammetric software packages that are not tightly integrated with LP360.

Layers: The Retained Photo layers of the project will be listed as available to be selected for export to the photo package.
Output Folder: Select an Output folder location by browsing and selecting from your file explorer, then select Export Photo Package to generate the photo package.
Export a single package for all layers: Creates a photo package where all the images are sorted into folders by camera serial number and there is a merged set of EO files.
Export a package for each layer (sub folders will be created): Creates a photo package where a subfolder is generated for each layer.
How to Export a Photo Package
- Select Export Photo Package
on the Sensor Tab to open the Export Photo Package dialog (Figure 1).
- Select the Retained Photos Layer(s) you wish to export.
- Select the desired output folder to write the geotagged images and associated camera calibration files.
- Select to "Export a single package for all layers" or "Export a package for each layer (sub folders will be created)".
- Select Export Photo Package to write the geotagged images and associated camera calibration files into the selected folder.
- A progress bar will inform you of the export progress.
- Once all photos have been exported you will receive notification of a successful operation and showing the number of images and calibration files written to the output folder. Select OK to continue.
The exported Photo Package contains:
- Images are sorted into folders by camera serial number and named with a Cycle_Flight_ImageNumberCameraPosition nomenclature.
- Camera calibration files are also placed in each camera folder.
- The xml files named Port_cameraserial#.xml, Starboard_cameraserial#.xml, or Nadir_cameraserial#.xml can be directly imported into Agisoft Metashape.
- The text files named Port_cameraserial#_P4D.txt, Starboard_cameraserial#_P4D.txt, or Nadir_cameraserial#_P4D.txt can be used in Pix4D.
- For other photogrammetric packages you may need to convert these camera calibration values to something applicable to the respective package. For example, Converting Focal Length from Pixels to Millimeters to use in Bentley Context Capture.
- While Metashape and PIX4D (as of v4.6.4) read the updated EXIF tags, some photogrammetric packages require the information be read from a file:
- The CSV file named “Cycle_Flight_image_geo_opk.csv” contains the image position file in geographic coordinates, height in meters, with the orientation angles represented as omega, phi, kappa in degrees for each Cycle/Flight combination that was exported.
- The CSV file named “merged_image_geo_opk.csv” is a merged file of all the Cycle/Flight combinations that have been exported into the same Exported Photo Package folder. This file is configured to be used in Pix4D.
- TopoDOT_Photos_merged or TopoDOT_Photos_CYYMMDD_hhmmss folders - contain the TopoDOT image project files, image list, and camera calibration files, either merged or by Cycle depending on the export selection, for streamlining your workflow for downstream processing and analysis in TopoDOT.
- Default.prj – Contains the coordinate reference system information from the project.
- A DEM folder is generated for use with 3DIS® processing.
