Begin by creating a new Visible Light Reconstruction Mission.
Under Photos, add your imagery to the project.
Under Aerotriangulation, ensure that the following is performed.
Under the Advanced menu, check the XML Output Format.
A menu will expand downwards.
Under Output Coordinate System select Known Coordinate System
Click on import PRJ next to Known Coordinate System and select the 4978.prj file provided here.
It is essential that the above steps are followed before commencing processing, otherwise the outputs will not be compatible with Trendspek.
Under 3D Model settings - we recommend high resolution for best results, ensure that the following items are checked.
Click on Start Reconstruction to begin the process.
Once complete, return to the mission library and click on the Export button for the project.
Ensure you export the photos, 3D Models and Aerotriangulation results as seen below.
Once exported, unzip the zip. We now must structure the data accordingly for Trendspek.
Within the zip, you will find a file called
