Drone mapping is flying a drone over an area in an automated grid, capturing hundreds of overlapping photos (or LiDAR scans), and processing them into accurate maps and 3D models. The main products are orthomosaics (one stitched, measurable map image), elevation models, contours, point clouds and 3D meshes. Surveyors, builders, farmers, insurers and inspectors use it because it's faster and cheaper than covering the ground on foot, and with RTK or ground control it can be accurate to a few centimeters.
Types of drone mapping
| Type | How | Best for |
|---|---|---|
| Photogrammetry | Overlapping photos matched by software | Orthomosaics, 3D models, open sites |
| LiDAR | Laser pulses build a point cloud | Ground under trees, power lines, topo |
| Multispectral | Narrow-band cameras, including near-infrared | Crop health, NDVI |
| Thermal mapping | Radiometric thermal images stitched | Solar farms, roofs, leaks |

What it's used for
- Construction: site progress, cut and fill, as-builts
- Surveying: topographic maps, contours, boundaries (with a licensed surveyor where required)
- Mining and aggregates: stockpile volumes
- Agriculture: field maps, drainage, crop health, spray route planning
- Insurance and real estate: roof measurements and property maps
- Public safety: crash and crime scene reconstruction
Deliverables
- Orthomosaic: a georeferenced, distortion-corrected top-down image you can measure on
- DSM/DTM: elevation of surfaces, or of bare ground
- Point cloud and 3D mesh: for volumes, models and inspections
- Contours and CAD exports for engineers
Accuracy
Two numbers matter. Relative accuracy is how well things measure against each other in the map. Absolute accuracy is how well the map lines up with real-world coordinates. Without RTK or ground control, a map can look perfect but sit a meter or more off. With an RTK drone or ground control points, a few centimeters is realistic. DJI rates its Zenmuse P1 at 3 cm horizontal and 5 cm vertical under its test conditions. Read what is RTK and ground control points.
Tools you need
- A drone that can fly automated grids. Enterprise drones like the Mavic 3 Enterprise and Matrice 4E have mechanical shutters and RTK. A Mini 4 Pro works only with DJI Fly, so it can't run automated grid missions from mapping apps, though it can make small, informal models from manual photos; see Mini 4 Pro mapping.
- Flight planning in DJI Pilot 2 or a third-party app.
- Processing software such as DJI Terra. See best drone mapping software.
- A Part 107 certificate for any paid work. See Part 107.
"XAG drone mapping" and spray drones
Spray drone makers, including DJI with its Agras line, build mapping into the workflow: the drone or a separate mapper surveys the field, marks obstacles, then plans the spray route. DJI's Agras T50 and T25 can map from their own camera. See how spray drones work.
