DJI Terra Pre-processing for the L1/L2 Processed workflow

DJI Terra is a software developed by DJI and it is used as part of the DJI L1/L2 Processed workflow.

This article explains the main steps to perform in DJI Terra before importing the data into LP360 Drone to continue with the workflow. This software will perform the trajectory processing step and the initial point cloud generation.

The information in this article may not be up to date with the latest changes in DJI Terra, and it is meant to be used as guidance on how to use the software. This guide was created using DJI Terra v4.3.0.

How to pre-process a DJI L1/L2 dataset in DJI Terra

1. Open DJI Terra
2. Go to the flight route section --> Press New Mission
3. In mission Type --> Select "LIDAR Point Cloud"
4. Give a name to the processing
5. In the "Files" section--> Press "Select Folder" and select the raw data folders to process
6. If processing in RTK you can continue to step 7.
If processing with PPK -->Press in "Base Station Center Point Settings" --> Input the coordinates of the base station.
7. Parameters section:
a) Scenario -->Point Cloud Processing
b) Point Cloud
          i) By Percentage-->High(100%)
          ii) Point Cloud Effective Distance Range --> 3m - 300m
          iii) Optimize Point Cloud Accuracy --> Disabled
          iv) Smooth Point Cloud -->Disabled

c) Ground Point Classification, DEM, Contour --> Disabled

d) Advanced Control and Check --> Known Coordinate System --> Select a known coordinate system. The recommended are:
        i) Global: WGS84 / UTM zone XX  + Geoid: default
        ii) North America: NAD83 (2011) / State Plane zone XX + Geoid: default
        iii) Europe: ETRS89 / UTM zone XX + Geoid: default

Note: During the Processing in LP360, LP360 will ask for the output CRS selected in DJI Terra

8. Press "Start Processing" --> Wait until the processing is done
9. Close DJI Terra software
10. Go to the default DJI Terra folder --> Find the DJI Terra Mission Folder for the project. This folder will be required during the processing in LP360.

Note: If you move the Raw data or the DJI Terra Mission Folder, LP360 will ask for the new location of these folders.
11. Continue the DJI L1/L2 Processed workflow in LP360 Drone
