Aerial Moisture Orthomosaic Mapping in Chilliwack, 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 Chilliwack and the Fraser Valley region — since 1999 as BC's leak detection specialists.

Flying Chilliwack: local context

Agri-industrial corridor with large low-slope roofs and military-heritage buildings.

Local property profile: Dairy and berry operations, fast-growing Sardis subdivisions, and military lands with legacy buried infrastructure.

Ground conditions: Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland.

How the Chilliwack survey runs

  1. 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. 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. 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. 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.

Chilliwack 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 Chilliwack?

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Chilliwack flights run under whatever airspace authorizations the location requires. Agri-industrial corridor with large low-slope roofs and military-heritage buildings. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

How do Chilliwack ground conditions affect what the survey reads?

Chilliwack ground is predominantly Fraser floodplain gravels and sands with mountain-fan gravels at the valley edges. Free-draining floodplain gravels are superb GPR ground — 3–4 m penetration is routine, among the best in the Lower Mainland. 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 Chilliwack?

Province-wide pricing — no regional premium for Chilliwack. 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.
