Let’s talk ↗DRONE SURVEYING / SPATIAL INTELLIGENCE
FROM CAPTURE TO CONTEXT
A short look at how aerial capture becomes a terrain model, screening layers and a map your team can explore.

SERVICES / START WITH THE QUESTION
Choose the question you need to answer. We scope the capture and outputs around it.
REAL PROJECT / RAIL SURVEY
Explore vegetation clearance, ground terrain and drainage from the same capture.
140M+ points in this rail survey example
Scrub from vegetation and the true 3D clearance envelope into terrain and drainage. Choose a chapter or play the tour.
Clearance intersections, flow paths and low areas are screening candidates for field or engineering review. Water shown is modelled, not observed.

Explore the interactive 3D model ↗
Slide between colour LiDAR and the classified ground model from the same project viewpoint. Review the formation, slopes and low ground with vegetation visually separated.
A classification view, not a before-and-after survey. Gaps in ground returns remain unknown; the model does not prove hidden drain condition.
Review interpreted cutting limits around the formation and side slopes. These two candidate boundaries stay separate across a processing exclusion.
Actual draft polygon geometry, simplified in presentation. Boundaries need review; they do not certify the crest, excavation limits or slope stability.
Discuss your earthworks scope ↗HOW IT WORKS / CAPTURE TO CONTEXT
Agree the site, intended use, detail and control. Capture with drone LiDAR and photogrammetry.
SCOPE + CAPTUREBuild georeferenced point clouds and terrain models. Derive the agreed screening layers with traceable parameters.

OUR APPROACH / CLEAR SCOPE. TRACEABLE EVIDENCE.
Agree the capture area, positioning requirements and deliverables before collection. Every model states its source and limitations. Screening helps qualified teams target field verification; it does not certify asset condition.
Repeat captures can track erosion, growth and surface change. Earthworks interpretation and high-voltage asset or conductor-clearance screening require an agreed scope, control and assurance.
