What a 3D Drone Survey Is For
We carry out RTK 3D drone surveys for construction sites, buildings, historic assets and land, across Italy. With the DJI Matrice 4E and the D-RTK 3 station we obtain a georeferenced metric model with centimeter-level absolute and sub-centimeter relative accuracy, delivered as a point cloud, 3D mesh, orthomosaic, DTM/DSM, contour lines and CAD sections, plus a web viewer to measure directly in the browser. Data is delivered in under 36 hours. Prices start from €350 plus VAT.

Technology Used
DJI MATRICE 4E
To deliver the highest-quality 3D surveys we use the DJI Matrice 4E, a professional drone with integrated RTK, designed to capture accurate data even in the most complex environments.
The integrated RTK system guarantees absolute centimeter-level and relative sub-centimeter accuracy.
DJI D-RTK 3 MOBILE STATION
To maximize the accuracy of the data collected by the drone, we also use the D-RTK 3 High-Precision GNSS Mobile Station, a latest-generation base station.
It guarantees flawless signal stability even in areas with poor coverage or magnetic interference.

It's the most practical tool we provide: it solves the problem of heavy 3D files clogging up computers. You'll receive a private, optimized web link to explore the survey in real time directly in your browser, with no complex software to install.
- • Smooth navigation on any device: open the link from a smartphone, tablet, laptop or Mac
- • Professional measuring tools: measure real distances, building heights, slopes and perimeters with millimetric precision
- • Instant calculation of excavations and stockpiles: select the outline of a site area to instantly calculate the volume in cubic meters
- • Instant sharing with clients and colleagues: just send the link via WhatsApp, email or attach it to a quote
- • Multi-layer views: switch with one click from the high-resolution photo to the elevation map or the point cloud
HTML5 Web Link / 3D Cloud Platform
A volumetric scan of space made up of tens of millions of coordinate points (X, Y, Z). Every single point carries its real spatial coordinate in the chosen geodetic system and the photographic RGB color.
- • Millimetric/centimetric accuracy verified with a D-RTK station
- • Essential starting point for reverse engineering, extraction of plans and elevations
- • Ground classification with filtering of vegetation and moving obstacles
- • Import into CloudCompare, Revit, AutoCAD and 3D scanning software
.LAS, .LAZ, .PLY, .E57
A continuous three-dimensional surface generated by connecting the cloud points through millions of triangles, onto which the photographic texture is applied at original resolution.
- • Perfect for architectural renderings, realistic visualizations and visual-impact simulations
- • Direct import into the main CAD and BIM software (Rhino, SketchUp, Blender, Revit)
- • Faithful documentation, frozen in time, of the as-built condition of the work
- • Ability to extract sections and profiles directly from the solid model
.OBJ + .MTL, .FBX, .3DS, 3D Tiles (.B3DM)
A huge orthorectified aerial photograph, free of perspective tilt and corrected for terrain variations, with a level of detail (GSD) down to a few millimeters per pixel.
- • Direct real-world measurements at 1:1 scale of surfaces, roofs, yards and property boundaries
- • Immediate integration with cadastral maps, regional technical maps and GIS software (QGIS, ArcGIS)
- • Essential tool for appraisals, site accounting and quantity take-offs
- • Perfect cartographic base for preliminary design
GeoTIFF, high-definition JPG + World File (.JGW)
Digital elevation maps: the DTM (Digital Terrain Model) represents the bare ground cleared of plants and buildings, while the DSM includes every volume above the ground.
- • Analysis of elevations, percentage slopes and rainwater runoff lines
- • Differential calculation between successive surveys to quantify earthmoving (cut/fill)
- • False-color map to read elevation differences and geomorphological issues at a glance
- • Integration into GIS software for territorial analysis and planning
GeoTIFF Raster, Grid ASCII (.XYZ)
2D and 3D vectors ready to be opened directly in AutoCAD with no intermediate conversion steps.
- • Primary and secondary contour lines with customizable interval (e.g. 20 cm, 50 cm, 1 m)
- • Longitudinal and cross-section tracing along any requested alignment
- • Files organized on separate layers for elevations, contour lines, excavation edges and buildings
- • Output ready for design and technical documentation
