Purchase the DJI P4 Multispectral Drone w/ RTK-2 Mobile Station Combo at www.tigersupplies.com.
third-party mapping software will require RGB images for aerial triangulation before stitching
NDVI maps.
What are the recommended camera settings? For beginner users, we recommend setting
the multispectral shooting mode to Auto, choose Average Metering as the metering mode,
and choose AE unlock.
Does the P4M support third-party software? Support for DJI Mobile SDK is coming soon.
Which vegetation indices are supported in DJI Terra? DJI Terra supports NDVI, GNDVI,
NDRE, LCI, and OSAVI, but does not have a vegetation index calculator function.
Which types of crops can information from the P4 Multispectral be used for? The data
from the multispectral bands captured by the P4 Multispectral can be used for a variety of
crops or vegetation. Use DJI Terra or third-party software to reconstruct vegetation index
maps like NDVI or NDRE maps that help you monitor plant health.
Can I run routine inspections on a given flight path using the P4 Multispectral? Yes, you
can plan flight missions and execute them repeatedly using GS Pro.
Can I reconstruct maps using third party software? Yes.
How do I calculate an appropriate flight altitude based on a Ground Sample Distance
(GSD) value? The GSD for the P4 Multispectral is (H/18.9) cm/pixel. You can calculate the
height of your flight mission based on the accuracy needed.
What’s the max mapping area in a single flight? The P4 Multispectral has a max mapping
area of approx. 0.47 km2 for a single flight at an altitude of 180 m, i.e., GSD is approximately
9.52 cm/pixel.
Do mission waypoints contain any altitude information? Relative altitude (relative to your
takeoff point) information is stored in the photos captured at waypoints.
Is the P4 Multispectral compatible third-party base stations? No, you cannot connect
third-party base stations to the P4 Multispectral or the remote controller via a radio station.
However, you can obtain data from a network RTK server via NTRIP protocol in 4G/Wi-Fi
network environment. Satellite observation data can also be saved in the aircraft for users to
conduct post processed kinematics (PPK) to complete their tasks.
