3.2.4.1.2. D-RTK 2 Mobile Station - PPK Data Confirmation
In PPK operation mode, you need to connect the D-RTK 2 Mobile Station to a computer. Copy the
base station file with a suffix of .DAT for the corresponding time slot, and paste the file in the same
folder as the raw point cloud data. DJI Terra can then calculate the difference automatically during
data post-processing.
3.2.4.2. Point Cloud Reconstruction - Operations in DJI Terra
1. Create a LiDAR Point Cloud task.

2. Click the grey folder icon.
To import multiple LiDAR point cloud data files of Zenmuse L2, you can put the files in the same
folder and directly import the folder. Alternatively, you can import the files one by one.
Note: Please make sure that the folder name doesn't have any special characters such as "," or "*",
otherwise there might be an issue in the processing.
3. Set Point Cloud Density (By Percentage).
Select a percentage indicating a high point cloud density. High, medium, and low point cloud density
correspond to the values of 100%, 25%, and 6.25%, respectively. Point cloud density affects only
the number of result points, and will not impact the result accuracy much.
4. Set Output Coordinate System.
5. Set Geoid Settings.
Use the default option (the default option is Ellipsoidal Height, while the EGM96 height and other
options all refer to the altitude above the sea level).
6. Set Point Cloud Effective Distance.
Use the default value (250 m) and do not modify it.
7. Set Optimize Point Cloud Accuracy.
Disable this feature. This feature optimizes the adjustment of the point clouds scanned at different
