Earthworks Made Easy with DJI Enterprise Drones

The DJI Matrice 4 series drone, allows construction teams to survey large sites in a fraction of the time and with far greater accuracy than traditional methods. In the video, a Colorado earthworks company demonstrates how they reduced a two-day manual survey to just one hour using the drone. This technology streamlines project planning, saves costs, and delivers highly detailed site data for earthwork and construction tasks.

How drones can assist in:

Surveying and Mapping

Surveying with drones

DJI’s Matrice 350 RTK (with Zenmuse P1 or L2) and Matrice 4E deliver highly accurate, efficient, and safe aerial surveying solutions. These platforms combine RTK positioning, high-resolution cameras, and LiDAR (Matrice 350 RTK) to capture centimeter-level georeferenced data over large or complex sites. The result is rapid creation of precise topographic maps, digital elevation models, and dense point clouds-dramatically reducing time, labor, and risk compared to traditional ground-based methods.

Core Points:

Centimeter-level accuracy using RTK and GNSS for georeferenced data
High-resolution sensors (Zenmuse P1: 45MP full-frame, global shutter; L2: integrated LiDAR and RGB camera)
Efficient coverage of large areas in a single flight, with robust flight times and obstacle avoidance
Seamless integration with software like DJI Terra for fast post-processing and actionable mapping outputs

‍

Example:
A survey team uses the Matrice 350 RTK with Zenmuse P1 to map a 3 km² construction site. With RTK and high-res imaging, they achieve 3 cm horizontal and 5 cm vertical accuracy, generating detailed orthomosaics and 3D models in a fraction of the time required by traditional surveying

Urban Planning and 3D Mapping with drones

DJI’s advanced drones transform urban planning and 3D mapping by enabling rapid, high-precision capture of complex cityscapes and infrastructure. The Smart Oblique Capture feature (Zenmuse P1) and multi-directional capture (Matrice 4E) provide rich datasets for creating detailed 3D reality models, supporting smart city planning, architecture, and infrastructure management. These models help planners visualize environments, assess development impacts, and make informed decisions.

Core Points:

Smart Oblique Capture and multi-directional imaging for detailed 3D city models
Efficient mapping of large urban areas with three- or five-directional capture, reducing flight time by up to 44%
Integration with urban planning and BIM software for visualization and analysis
Supports applications in city planning, heritage conservation, and infrastructure management

‍

Example:
An urban planning department deploys the Matrice 350 RTK with Zenmuse P1 for a Smart Oblique Capture mission, generating a high-fidelity 3D model of a downtown district. Planners use this model to simulate new developments, analyze line-of-sight, and optimize land use

Property Surveying and Mapping with drones

DJI drones provide property surveyors with fast, accurate, and cost-effective tools for boundary mapping, cadastral surveys, and land development. The Matrice 350 RTK with Zenmuse P1 or L2 enables centimeter-level boundary definition and detailed terrain modeling, even in challenging environments. These capabilities streamline property records, facilitate legal documentation, and support land management with minimal fieldwork.

Core Points:

Centimeter-level boundary mapping for cadastral and property surveys
Rapid data collection over large or inaccessible properties, including forests and water bodies
LiDAR (Zenmuse L2) enables accurate mapping even through dense vegetation or complex terrain
Outputs compatible with GIS and land registry systems for legal and planning use

‍

Example:
A land surveyor uses the Matrice 350 RTK with Zenmuse L2 to perform a cadastral survey in a wooded area. The LiDAR penetrates canopy cover, producing a precise 3D point cloud and boundary map suitable for legal documentation and submission to land authorities
