Aerial Moisture Orthomosaic Mapping in Nelson, BC
The deliverable layer: survey-grade, georeferenced moisture orthomosaics — radiometric thermal fused with RTK photogrammetry — exported to CAD and GIS for engineers, consultants, and owners who need leak evidence they can measure from. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving Nelson and the West Kootenay region — since 1999 as BC's leak detection specialists.

Flying Nelson: local context
BC's best-preserved heritage downtown on a steep grid — no-contact aerial inspection suits century-old façades perfectly.
Local property profile: BC's best-preserved heritage town — 1900s homes on terraced streets, with retaining walls and stairs concealing service runs.
Ground conditions: Thin mountain soils put services shallow between rock; Nelson's heritage grid hides century-old galvanized and clay lines that reward careful tracing.

How the Nelson survey runs
- 1
Deliverable specification
Coordinate system, accuracy requirements, export formats, and analysis goals defined with your technical team before the first flight — the survey is built backward from the document you need.
- 2
RTK survey flight
Systematic photogrammetry plus radiometric thermal at fixed parameters, with RTK positioning — every pixel of both datasets lands within centimetres of its true coordinates.
- 3
Fusion processing
Visual orthomosaic, thermal orthomosaic, and (where relevant) elevation model processed and co-registered; moisture anomalies digitised as measurable polygons with areas and coordinates.
- 4
Engineering handoff
GeoTIFF, DWG/DXF overlays, shapefiles or the formats your workflow uses — plus the annotated PDF for the humans. Raw radiometric frames available for your own analysis.
Nelson questions, answered
How is this different from an ordinary drone thermal survey?
Rigor and usability. A screening flight answers 'where should we look?' An orthomosaic deliverable answers 'exactly how large, exactly where, against exactly which drawing?' — survey-grade positioning, fixed capture parameters, co-registered thermal and visual mosaics, and anomalies digitised as measurable polygons. It is the difference between a flashlight and a drawing.
Can our engineers analyse the raw data themselves?
Yes, and we encourage it — radiometric frames carry per-pixel temperature data, and we deliver them alongside the processed mosaics. Consultants run their own thresholds and interpretations; our processing gives them a co-registered, georeferenced foundation rather than a black-box conclusion.
What accuracy can we actually count on?
With RTK positioning and proper ground control, planimetric accuracy lands in the low-centimetre range — sufficient to scale moisture polygons, quantify areas for repair pricing, and overlay repeat surveys for change detection. Accuracy specs are stated per project and verified against control, not just claimed.
Can you legally fly drone leak surveys in Nelson?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Nelson flights run under whatever airspace authorizations the location requires. BC's best-preserved heritage downtown on a steep grid — no-contact aerial inspection suits century-old façades perfectly. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How do Nelson ground conditions affect what the survey reads?
Nelson ground is predominantly steep till and colluvium over granite above Kootenay Lake. Thin mountain soils put services shallow between rock; Nelson's heritage grid hides century-old galvanized and clay lines that reward careful tracing. For buried-leak work that matters: escaping water changes the moisture and thermal behaviour of exactly that ground, and our analysts interpret the surface signal against the local soil character — then our acoustic ground crews confirm the suspect zones before anyone digs.
What does aerial moisture orthomosaic mapping cost in Nelson?
Province-wide pricing — no regional premium for Nelson. Single-site surveys typically start in the high hundreds; network corridors, portfolios, and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
