How we prove the work.
From field control to final deliverables, every result is tied to a documented method and measurable checks.
- Drone capture
- Gaussian splat
- Interactive twin
How a live twin is made.
Drone capture
Orbit and grid flights photograph the site from every side, tied to ground control.
Gaussian splat
The photos are trained into a Gaussian splat: millions of small, soft 3D points that render the site as it looks.
Interactive twin
Floors, picture hotspots, sun study and area search are fitted over the splat and published to a link that opens on a phone.
Accuracy you can check.
We report the error, not a promise. Every delivery states its method and its measured accuracy.
RTK / PPK positioning
Each drone image is positioned against a reference station.
Ground control points
Surveyed targets tie the model to real coordinates.
Independent check points
Points kept out of processing measure the true error.
RMSE in every report
You see the measured error for your site, not a brochure figure.

What the error number means.
RMSE is the typical difference between our model and independent check points surveyed on the ground, in the units of the data. We report it for x, y and z, with the number of check points it came from, the coordinate system and the vertical datum.
For context, two published reference points. They are standards and research results, not a Spyder guarantee: your report gives the figure measured on your site.
≤10 cm
vertical RMSE for USGS 3DEP Quality Level 1 lidar
QL1 also requires at least 8 pulses/m² and nominal spacing of 0.35 m or less. A published standard, not a Spyder guarantee.
USGS · 3DEP fact sheet 2025-3044 (2025) (opens in a new tab)0.11 m vs 0.36 m
ground-model RMSE under medium vegetation: UAV laser scan vs photogrammetry
Vegetation taller than 60 cm. Laser scanning reached the ground where photos could not.
