Validate the input
Check survey coverage, density, noise, coordinate system and units. Delimit the analyzed section and record missing areas.

Tunnel geometric control with 3D survey data
Geometric control compares the observed excavation with a documented reference. A useful result must explain where it was measured, against which design and under which criteria.
Illustrative views, not customer results. Embedded interface labels remain in Spanish. Results depend on the survey data and documented engineering criteria.
A reviewable chain of evidence
Define the comparison
Use the correct alignment, station positions and design revision. Document tolerances, signs and measurement directions.
Review before consolidating
Inspect individual cross-sections before summarizing areas or volumes. Keep the source, criteria and output linked.
Limits that must remain visible
Occlusions and noise
Missing surface is not proof of an excavation boundary. Equipment, services, dust or unrelated objects may need separate review.
Reference errors
An incorrect CRS, alignment, chainage or design section can shift the comparison and undermine all downstream quantities.
Engineering responsibility
Geometric deviation alone does not establish geotechnical stability, structural adequacy or contractual acceptance.
Start with your tunnel, your data and a clear validation objective.
Request a technical evaluation focused on cross-sections, as-built versus design comparison, quantities or traceable deliverables. The 15-day evaluation period begins when the licence is activated, subject to prior coordination and availability.
No automatic download. Commercial licensing and deployment scope are agreed after technical review; no unverified price or guaranteed outcome is advertised.
