Warning: We've experienced numerous problems with DJI Terra, leading to inconsistent export results. Currently, we cannot guarantee the compatibility of any DJI Terra datasets with Trendspek.

Begin by creating a new 3D Model Reconstruction Mission.

Add your imagery to the project and select your modelling settings - we recommend High resolution for best results. Under Reconstruction Output 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 want to structure the data accordingly for Trendspek.

  1. Within the zip, you will find a file called BlocksExchangeUndistortAT.xml in folder AT/. Copy this file to your clipboard.

  2. Paste BlocksExchangeUndistortAT.xml inside models/pc/0/terra_b3dms/ and rename the file to matrix.xml

  3. rename models/pc/0/terra_b3dms/ to models/pc/0/3d-tiles/

  4. ZIP models/pc/0/3d-tiles/ into 3d-tiles.zip

Upload to Trendspek

Start by navigating to https://trendspek.cloud/myuploads If you are unable to access this page, you may not have sufficient privileges. Contact Trendspek Support or your account admin to confirm.

Upload the following items in one go:

  • 3d-tiles.zip

  • the jpg imagery found within the ZIP images/survey/

    • Do not drag a folder of imagery to Trendspek, instead, drag the imagery itself or use the file picker

The Trendspek team will perform a final quality control step before making your dataset available in your account. You will receive an email once it is ready,
