Where drones fit in public works

Big assets, small crews, and a public watching

Municipal and utility staff look after roads, parks, dikes, reservoirs, bridges, culverts, landfills, towers and lines spread across large areas. A drone gives them current imagery and measurements of all of it without closing a lane or sending someone up a structure. Mapping flights produce orthomosaics, elevation models and point clouds that drop straight into your GIS. Inspection flights give close-up photos and thermal images of assets people can't easily reach.

Public bodies carry obligations private clients don't: procurement rules, privacy law that applies to government, records retention, freedom of information requests, and residents who will ask why a drone was over their street. The work has to be defensible, not only useful.

DroneLink keeps each site or asset on its own project record: the order, every flight, every deliverable, with dates. When a council report, an auditor or an access request asks what was captured and when, it is in one place. Mapping deliverables arrive as GeoTIFF, LAS/LAZ, DXF and PDF, ready for ArcGIS, QGIS or Civil 3D.

What goes wrong

Problems public owners run into

No baseline when the hazard arrives

After a flood or slide, engineers need to know what the slope, channel or dike looked like before. Often the latest data is old aerial photography.

How we handle itBaseline mapping of known hazard areas, repeated on a schedule, so post-event surfaces can be compared. In-browser comparison between flights is coming; today the surfaces compare in your GIS. →

Capital project progress nobody can verify

Council asks whether the contractor is on schedule. Staff rely on the contractor's own photos.

How we handle itOwner-controlled progress flights on a fixed plan, stored on the project record. →

Privacy complaints after the flight

Residents see a drone over their yard and call council. Nobody can say what was captured or how it is stored.

How we handle itDo the privacy impact assessment first, publish notice, and keep the flight and data record ready to answer questions. →

Procurement that buys a flight, not a result

Specs that say 'drone survey' get bids that can't be compared: different accuracy, formats and data rights.

How we handle itSpecify outcomes: deliverables, accuracy and checks, datum, formats, data ownership and retention. →

What to order when

Common municipal and utility work

Need	Order	Deliverable
Capital project	Pre-construction mapping, then monthly progress	Orthomosaic, surface model, progress photo sets
Flood and dike management	Baseline mapping of dikes and channels; repeat after high water	Elevation models, cross-sections, orthomosaic
Landslide-prone slopes	Baseline LiDAR where vegetated; repeat after events	Terrain model, point cloud, change surfaces
Landfill and aggregate	Periodic volume surveys	Volume reports, surfaces
Buildings and facilities	Roof, envelope and thermal inspection	Photo sets, thermal images
Towers, lines, substations	Close-up inspection within utility limits of approach	Photo and thermal sets per asset
Parks and planning	Current orthomosaics of growth areas	GeoTIFF for GIS

Flood and landslide assessment

The flight before the event is the one that matters

After an atmospheric river or a slope failure, everyone wants aerial imagery at once. The imagery is useful, but the measurement that engineers need is change: how much ground moved, where the channel shifted, how far a dike crest settled. Change needs a before surface. Communities that fly their known hazard areas on a schedule, with the same control and datum each time, can answer those questions in days rather than weeks.

Pick the sensor for the terrain. Open dikes, channels and bare scarps map well with photogrammetry. Vegetated slopes and forested ravines need LiDAR to see the ground. Keep flights clear of active response: firefighting, rescue and medevac aircraft have priority, and the pilot flies only with the incident team's agreement and within any airspace restriction.

Privacy impact assessments

Plan privacy before the first flight

Government drone programs fall under public-sector privacy law, not just aviation rules. In British Columbia, the Freedom of Information and Protection of Privacy Act requires public bodies, including municipalities, to complete a privacy impact assessment for new projects, programs and systems, and the BC privacy commissioner publishes guidance on public-sector surveillance. In Ontario, municipal institutions follow MFIPPA and the commissioner recommends PIAs. Québec's public-sector access law requires assessments for many projects involving personal information. In the United States, state privacy and public records laws vary; several states limit government drone use.

A useful PIA for drone work answers: why the flight is needed, what could be captured incidentally (people, plates, backyards), how imagery is reduced to what the purpose needs, who can access it, how long it is kept, and how residents are told. The contractor should be able to support every one of those answers.

On the DroneLink record: Outcome-based specs; see the steps below.

Emergency management

They need from you: Fast imagery after events without getting in the way of response aircraft.
You need from them: Coordination with the operations centre and airspace restrictions.
On the DroneLink record: Flights only with the incident team's agreement.

Utility owners

They need from you: No contact with energized equipment.

Procurement

Writing a drone scope you can award

State the outcome

What decision the data supports, the area and the dates.

Specify deliverables

Formats, datum, resolution, and accuracy with how it will be checked.

Set compliance requirements

Transport Canada certificates (or FAA Part 107 in the US), liability insurance, workplace safety registration, and privacy obligations.

Settle data rights

Who owns the imagery, where it is stored, and retention and deletion.

Evaluate on qualifications and method

Where mapping counts as surveying, many public owners use qualifications-based selection. Follow your trade agreement thresholds and policy.

Questions

Does a municipality need a privacy impact assessment for drone flights?

In BC, public bodies must complete a PIA for new programs and projects under FIPPA. Elsewhere requirements differ by province and state, but privacy commissioners broadly expect an assessment before a public body starts capturing imagery that can include people. Check your act and your own policy before the first flight.

Can drones be used after a landslide or flood?

Yes, once the incident team agrees and airspace restrictions allow. Rapid imagery helps triage; measured surfaces help engineers. Baseline data flown beforehand makes post-event comparison far more useful, because it shows exactly what changed.

Do municipal drone flights follow the same rules as commercial ones?

In Canada, yes: CARs Part IX applies to everyone. In the US, agencies can hire Part 107 operators or operate under a public aircraft certificate of authorization.

Can drone imagery be requested under freedom of information?

Generally, records held by a public body, including imagery held by a contractor on its behalf, can be subject to access laws, with exceptions. Plan retention, storage and redaction before flying so a request does not turn into a search.

How accurate is drone mapping for municipal engineering?

With ground control or RTK/PPK, typically a few centimetres as general industry knowledge; without, decimetres to metres. Specify checkpoints in the scope.

Can drones inspect power lines and towers?

Yes, within the utility's limits of approach and procedures. See telecom and utilities inspection.

What should a municipal drone RFP include?

The outcome, area and dates; deliverables with formats, datum and accuracy checks; certificates and insurance; privacy and records obligations; and data ownership. Outcome-based scopes produce bids you can compare.

Can DroneLink work outside Vancouver Island?

Tell us where. The operator network is being built; we confirm a certified local operator before you commit. See areas.
