DJI Matrix 4E + RTK Surveying Pack

DJI Matrix 4E Surveying Package: the complete solution for your surveys in Belgium

The DJI Matrix 4E Surveying Pack brings together all the equipment needed to carry out centimeter-accurate photogrammetric surveys. Designed for surveyors, planners, real estate experts and construction contractors, this package covers up to 2.8 km² per flight thanks to the M4E’s ortho-tridirectional capture. It is a turnkey solution, ready to deploy in the field upon receipt.

In Belgium, the RTK correction networks Walcors (Wallonia) and Flepos (Flanders) are accessible free of charge. The Cellular Dongle 2 included in this pack connects the Matrice 4E to these networks via 4G. The result: direct georeferencing without ground control points (GCPs) for most missions.

Surveying + RTK Pack or Photogrammetry Pack: which one should you choose?

This Surveying Pack adds a D-RTK 3 Multifunctional Station and a D-RTK 3 mast/tripod kit to the DJI Matrice 4E, guaranteeing centimeter-level autonomous RTK accuracy even without mobile network coverage. The DJI Matrice 4E Photogrammetry Pack instead offers 4 additional batteries and 4G connectivity, for general mapping, inspection and surveillance missions without an autonomous RTK base station.

Surveyors, design offices and construction contractors: this Surveying Pack is the reference choice for cadastral surveys and precision measurements. For more general mapping needs, the Photogrammetry Pack is a lighter alternative.

Thanks to this configuration, you have both a wireless NTRIP solution and a stand-alone base station as a backup. This dual approach ensures the continuity of your operations, even in rural areas with poor 4G coverage.

Matrice 4E multi-camera system

The DJI Matrice 4E has three complementary cameras. The wide-angle camera uses a 20 MP 4/3-inch sensor with a mechanical shutter. This shutter eliminates rolling shutter distortion, which is essential for sharp images in fast flight. In addition, the built-in distortion correction (Distortion Correction 2.0) improves the geometric fidelity of the shots.

The medium tele camera (1/1.3-inch sensor, 48 MP, 70 mm equivalent) and the telephoto camera (1/1.5-inch sensor, 48 MP, 168 mm equivalent) complete the system. In particular, they allow the close inspection of details during site inspection or roof inspection missions.

The built-in laser rangefinder provides a range of 1,800 m with an accuracy of ± (0.2 + 0.0015 × D) meter. It makes it easy to measure distances, surfaces, and position points of interest directly from the DJI Pilot 2 app.

Centimeter RTK accuracy

The RTK module built into the Matrice 4E supports GPS, Galileo, BeiDou and GLONASS constellations (the latter when RTK is enabled). In RTK Fix mode, the accuracy reaches 1 cm + 1 ppm horizontal and 1.5 cm + 1 ppm vertical. For surveying and mapping, this accuracy eliminates the need for Ground Control Points (GCPs) with the wide-angle camera, significantly speeding up the field workflow.

Missions covered by this drone topography pack

• Cadastral surveys and measurements of plots in Wallonia and Flanders
• Site monitoring: cubature calculations, contour lines, cross sections
• Digital Surface Models (DSM) and Digital Elevation Models (DTM)
• High-resolution ortho-mosaics for urban plans and planning permits
• Roof inspections as part of real estate appraisals
• Mapping of quarries, landfills, agricultural sites and industrial areas

4-step photogrammetric workflow

The workflow with the DJI Matrice 4E Surveying Pack is simple and efficient. Each step is optimized to reduce time spent in the field and in post-processing.

1. Planning in DJI Pilot 2: Set the flight area, altitude, and overlap rate (75-80% recommended). The RC Remote Control Plus 2 allows you to create 3D flight plans directly in the field, without a laptop.
2. Automated flight: The M4E executes the flight plan with real-time RTK positioning. Omnidirectional obstacle avoidance makes missions safer even in complex environments (construction sites, wooded areas, urban environments).
3. Processing in DJI Terra: Generate ortho-mosaics, point clouds, DSMs, and terrains. The software supports advanced M4E-specific distortion correction and offline PPK processing of images.
4. Export: The data is compatible with AutoCAD, QGIS, ArcGIS, Agisoft Metashape, and other common GIS software.

Free RTK networks in Belgium: Walcors and Flepos

Belgium offers a major advantage to drone surveying professionals: two free RTK correction networks cover the entire territory. Walcors is managed by the SPW in Wallonia, while Flepos is operated by Digitaal Vlaanderen in Flanders. The Cellular Dongle 2 in the pack connects the drone to these networks in real time via 4G, without an additional subscription.

For areas with poor mobile coverage, the D-RTK 3 Multifunctional Station takes over. It provides local RTK corrections and can also serve as a video transmission relay at altitude, a feature exclusive to the Matrice 4 series.

Data and deliverables for surveying firms

With its built-in RTK module, this pack delivers RTK Fix accuracy of 1 cm + 1 ppm horizontal and 1.5 cm + 1 ppm vertical, without ground control points (GCPs) for most missions.

Processing in DJI Terra generates orthophotos and digital surface models (DSM) exported in GeoTIFF format (UTM projection), as well as point clouds exportable in LAS format. These deliverables are compatible with AutoCAD, QGIS, ArcGIS and Agisoft Metashape.

Drone regulations and EASA category

With a take-off weight of 1,219 g, the DJI Matrice 4E exceeds the threshold of 900 g in the Open A1 subcategory. Depending on the class marking of the device, it may operate in subcategory A2 or require authorization in category Specific. In Belgium, the DGTA (Directorate-General for Air Transport) manages authorisations. For routine topography missions in open areas, the regulatory framework remains accessible. We accompany you in the steps if necessary.
