- Gaussian-splat digital twins with XGRIDS LCC
Inspection
Close detail, with location attached.
Details
- Bridges, towers, roofs and facades

Compare
Lidar vs photogrammetry
Photogrammetry
Overlapping photos become a true-color map, a surface model and a textured mesh.
Best for- Open ground
- Stockpiles
- Construction progress
- Facades & roofs
- Orthomosaics
How it differs
- Needs daylight and visible texture on the surface
- Sees the top of vegetation, not the ground under it
- Examples: Zenmuse P1, Matrice 4E, WingtraRAY with MAP61
Lidar
Laser pulses measure the surface directly and build a dense point cloud.
Best for- Vegetated terrain
- Corridors & power lines
- Thin structures
- Indoors & underground (SLAM)
- Ground models
How it differs
- Multiple returns can reach the ground through gaps in vegetation (Zenmuse L2 records up to 5)
- Handheld SLAM keeps scanning where GNSS drops out, such as indoors
- Examples: Zenmuse L2, Wingtra LIDAR, XGRIDS Lixel
Often, both.Many jobs pair a lidar ground model with a photo orthomosaic. Tell us the deliverable and we’ll match the sensor.
Deliverables
What you get back
Orthomosaic
A true-scale, distortion-corrected map image.
More
Measure distances and areas directly. Wingtra software exports it as GeoTIFF.
DSM / DTM
Surface and bare-earth elevation models.
More
The DSM includes buildings and canopy. The DTM is the ground only, built from ground-classified points. Wingtra software exports DSMs as GeoTIFF.
Point cloud
Millions of measured 3D points.
More
From lidar or photogrammetry. DJI Terra exports PNTS, LAS, PLY, PCD and S3MB; Wingtra software exports LAS or CSV.
Contours
Elevation lines for plans and CAD.
More
Generated from the DTM at the interval your plan set calls for.
3D mesh
A textured, walkable 3D model.
More
Built from oblique and nadir imagery. Useful for facades, stakeholder reviews and digital twins.
Workflow
Plan > Fly > Process > Deliver
Plan
Boundary, resolution, control.
Details
- Set the area, ground sample distance and overlap
- Place ground control and independent check points
- Check airspace and site access before the flight
Fly
Automated flight lines.
Details
- The drone flies the planned route
- Positions logged with RTK or PPK
- Handheld SLAM for areas the drone can’t see
Process
DJI Terra, Wingtra software, XGRIDS LCC.
Details
- DJI Terra: 2D and 3D reconstruction from imagery, DJI lidar processing and Gaussian splatting
