Marking the Calibration Board

1. Click the photo displayed on the main screen on the left to add a point as a mark of the edge of

the calibration board in the photo.

2. Drag the edge point to adjust the position.

3. Click

to delete all the points in the selected photo.

4. Mark the calibration board for each photo accordingly.

5. The marks of the calibration board will be applied to the next group of images of the calibration

board. Drag the edge points to adjust if needed.

Vegetation Index Outputs

DJI Terra supports 5 types of vegetation indices: NDVI, LCI, GNDVI, OSAVI, and NDRE, each

requiring photos from different spectral bands. DJI Terra will display the indices that can be

calculated according to the imported photos. There will be notications under output index if any

photos are missing in the required band. After reconstruction, click the buttons for different indices

to view the results.

Even if only one photo is missing from a required band for the desired vegetation index, it is

considered that the information of that whole band is missing. Users can view which photos

are missing in the required band in the photo list.

File Format and Storage Path of 2D Multispectral Maps

The 2D multispectral map reconstruction results are raster data in the GeoTIFF format which can be

used in third party software compatible with GeoTIFF format. The results include multispectral index

maps for each index, 2D orthographic maps in RGB and for each of the spectral bands. The default

storage path of the 2D multispectral map files can be found below. In the reconstruction page,

users can open the current mission folder using the keyboard shortcut “Ctrl+Alt+F”. This cache

directory can be changed in Settings.

The default storage path of the multispectral index maps is

C:\Users\<computer name>\Documents\DJI\DJI Terra\<DJI account name>\<mission code>\map\

index_map

The default storage path of the 2D orthographic maps in RGB and for each of the spectral bands is

C:\Users\<computer name>\Documents\DJI\DJI Terra\<DJI account name>\<mission code>\map

The result.tif le is the RGB 2D orthographic map. The result_XXX.tif le is the 2D orthographic map

for the spectral band corresponding to “XXX” in the le name.

Agricultural Application

For 2D map reconstruction (Field and Fruit Tree) and 2D multispectral map reconstruction, click on

the right of the Agricultural Application bar to enter the page. Users can plan operations for elds or

fruit trees on the map.
