DJI P4 Multispectral

From farm to numbers

Get immediate plant health insights

P4 Multispectral consolidates the process of capturing data that provides insight into crop health and vegetation management. DJI created this platform with the same powerful performance standards that DJI is known for, including a maximum flight time of 27 minutes and a transmission range of up to 7 km1 with the OcuSync system.

Collecting agricultural imagery is now easier and more efficient than ever with an integrated stabilized imagery system that collects comprehensive data sets right out of the box. Access information collected by an RGB camera and a multi-spectral camera array with 5 cameras covering blue, green, red, red-edge and near-infrared bands - all at 2 MP with global shutter, on a 3-axis stabilized gimbal.

Built-in spectral sunlight sensor for accurate results

A spectral sunlight sensor built into the top of the drone captures solar irradiance, maximizing the accuracy and consistency of data collection at different times of the day. Combined with post-processed data, this information yields the most accurate NDVI results.

Meaningful data at your disposal

View RGB and NDVI streams

Simply having aerial images is not enough for agricultural professionals who want to know more. Go from a preliminary Normalized Difference Vegetation Index (NDVI) analysis to a live RGB feed to immediately visualize treatment areas and quickly make targeted treatment decisions.

Accuracy to the nearest centimeter

Get accurate real-time positioning data on footage captured by all six cameras with DJI's TimeSync system, which provides centimeter-accurate measurements. The TimeSync system continuously aligns the flight controller, RGB and BW cameras, and RTK module, fixing positioning data in the center of the CMOS and ensuring that every photo uses the most accurate metadata. All cameras go through a rigorous calibration process in which radial and tangential lens distortions are measured. The distortion settings collected are saved in each image's metadata, allowing post-processing software to adjust them uniquely for each user.

Compatibility with D-RTK 2 mobile station and NTRIP

Improve RTK positioning accuracy without an internet connection by connecting the P4 Multispectral to the D-RTK 2 high-precision GNSS mobile station and NTRIP (Network Transport of RTCM via Internet Protocol)2, or store satellite observation data for use for post-processing kinematics (PPK).

The start of smart farming missions

Plan flights

Plan flights, execute automated missions and manage flight data using GS PRO - DJI's leading iOS app for flight planning.

Capture data

Efficiently collect multispectral images over a large area using the P4 Multispectral and get an overview of problem areas.

Analyze the data

Easily access and process aerial data by applying plant-specific metrics and parameters to acquire desired plant health outcomes.

Act on the data

Implement targeted treatments on areas that need special attention based on accurate drone data.

Real applications of the Phantom 4 Multispectral

Precision farming

During all growing seasons, multispectral imagery can benefit agricultural professionals by providing information invisible to the human eye across the electromagnetic spectrum. By having access to this data and subsequently obtained Vegetation Index data such as NDRE and NDVI, farmers can make timely and informed decisions on crop treatment, resulting in reduced costs, d save resources and maximize returns.

Environmental monitoring and inspection

Routine inspections and facility maintenance can be made smarter and more efficient with the use of the P4 Multispectral. Leverage its actionable multi-spectral information to monitor forest health, measure biomass, map shorelines or manage riparian vegetation while protecting habitats or ecosystems, and much more.
