How It Works

From Aerial Capture to Processed Deliverables

Scan reference → Model → QA

01

Airspace, access, GCPs

Flight Planning

We confirm which areas are in scope, plan flight coverage, review airspace requirements, and coordinate ground control when the project requires georeferenced outputs. Airspace authorization is handled before mobilization.

02

UAV flight, planned coverage

Aerial Capture

The UAV flies a planned pattern over the agreed area under applicable Transport Canada RPAS requirements. Coverage is confirmed before the crew leaves the site.

03

Orthomosaics, point clouds, QA

Processing and Handoff

Captured imagery is processed into the agreed deliverables and reviewed for coverage, georeferencing, and completeness against the agreed scope before handoff.

Good to Know

What Drone Capture Does Not Include

  • Interior conditions of any enclosed space
  • Below-grade or buried conditions
  • Concealed roofing layers or below-membrane conditions
  • Structural conditions not visible from above
  • Areas physically obstructed from the planned flight path
  • Legal land survey, boundary survey, or cadastral documentation
  • Structural engineering inspection or roof condition certification
  • Engineering sign-off or permit consulting

Drone services produce aerial documentation of visible conditions during the planned flight. On-Site Measurements does not provide engineering sign-off, structural assessment, roof condition certification, or legal land survey services.

Is This the Right Service?

Good fit when...

  • Roof documentation without requiring physical roof access
  • Construction site progress records across a project timeline
  • Aerial site context or exterior reference for planning and design teams
  • Large outdoor areas or facility exteriors where ground-based access is limited

We use drones to capture aerial data for site documentation, roof condition records, construction progress, and exterior building reference. The output is georeferenced imagery, orthomosaics, and photogrammetric 3D data that project teams can use as an aerial reference for planning, documentation, and progress tracking within the agreed scope.

Drone capture works from the air. It documents what is visible from above: roof surfaces, site conditions, building exteriors, and construction progress across a project timeline. It does not capture interior conditions, below-grade conditions, or concealed elements. Understanding what aerial capture shows, and what it does not show, matters before scoping a project.

This page explains what the service includes, how each supporting workflow fits, how the field process runs, what deliverables are available, and what to confirm before a project starts.


Drone Services at On-Site Measurements is aerial data capture using UAV platforms for site documentation, roof condition records, construction progress, and exterior mapping. Deliverables include georeferenced imagery, orthomosaics, photogrammetric point clouds, and elevation-derived outputs, depending on the agreed scope. Aerial mapping, drone photogrammetry, roof inspections, and site progress capture are all within this service. They are not separate offerings.

Drone capture produces aerial data from a planned flight over the agreed area. The data is processed into orthomosaics, 3D data, or other deliverables depending on what the project requires. Deliverables are not automatically generated by the drone. Processed outputs are prepared from the captured imagery and reviewed before handoff.

This service covers aerial data capture and processed deliverables from it. It does not include interior documentation, below-grade conditions, or structural assessment. If your project also requires interior existing-conditions documentation, terrestrial laser scanning is the appropriate method for that scope. See our 3D laser scanning services for detail on how that workflow runs.


Frequently Asked

Common Drone Services Questions

Ask a question
  • Drone photogrammetry is the workflow where overlapping drone imagery is processed to reconstruct spatial data: orthomosaics, photogrammetric point clouds, and digital surface models. The drone captures the imagery; photogrammetric processing produces the 3D data from the image overlap. Deliverables are produced from the captured data and reviewed before handoff. They are not automatically generated in final form by the drone during the flight. Drone photogrammetry is a supporting phrase for Drone Services, not a separate offering.

  • Aerial mapping is the use of drone capture and photogrammetric processing to produce georeferenced imagery and spatial data of a site or area. Common outputs include orthomosaics, digital surface models, and photogrammetric point clouds. Aerial mapping is a documentation and planning reference service. It is not a cadastral survey, boundary survey, legal land survey, or licensed topographic survey. Aerial mapping is a use case within Drone Services, not a separate offering.

  • Drone roof capture documents visible surface conditions from above: roof geometry, drainage features, penetrations, visible surface conditions, and roof-level elements accessible during the flight. It does not document concealed roofing layers, below-membrane conditions, or structural conditions not visible from the air. Drone roof documentation is not a structural engineering inspection, not a roofing warranty inspection, and not an insurance inspection certification. If specific concealed conditions are critical to your project, alternate methods should be discussed before the scope is confirmed.

  • Site progress capture is periodic drone flights over a construction site to produce dated aerial records of progress across a project timeline. Flights are planned to repeat a consistent coverage pattern so that imagery and data from different dates can be compared. Common deliverables include dated orthomosaics, georeferenced imagery, and aerial video when agreed. Site progress capture is a use case within Drone Services, not a separate offering.

  • Deliverables depend on the agreed scope. Options that may be available when scoped include georeferenced orthomosaics (GeoTIFF), photogrammetric point clouds (LAS/LAZ, E57), digital surface models (GeoTIFF), annotated aerial imagery, and aerial video. Elevation-derived outputs such as contours may be available when in scope. Not every project requires every deliverable type. Format and scope are confirmed before work begins.

  • Accuracy depends on flight planning, image overlap, ground control or other control methods when included, site conditions, processing workflow, and required deliverables. Ground control points can improve spatial accuracy when the project requires georeferenced outputs or tighter spatial control. Accuracy requirements should be discussed during scope confirmation so the flight plan and processing approach can be planned around them where feasible.

  • Commercial drone operations in Canada are governed by Transport Canada under the Canadian Aviation Regulations, Part IX. Drone operations are planned under applicable RPAS requirements. The required pilot certificate, aircraft requirements, airspace authorization, and scheduling constraints depend on the drone, site location, proximity to people, aerodrome proximity, airspace classification, and the type of operation. Projects near aerodromes or in controlled airspace may require authorization through NAV CANADA, and some military or DND-controlled airspace situations may require Department of National Defence involvement before flights can proceed. For current regulatory information, refer to Transport Canada's drone safety resources at tc.canada.ca/en/aviation/drone-safety.

  • Several factors influence project cost: Area to cover: Larger sites require more flight time and more processing time Project type: Roof documentation, site mapping, and construction progress capture each have different field and processing requirements Required deliverables: An orthomosaic requires different processing time than a full point cloud and surface model package Ground control: GCP placement and control measurement add field time and cost when in scope Flight frequency: Periodic progress flights are scoped differently from one-time capture Airspace and access: Controlled airspace authorization, occupied facilities, and access restrictions affect scheduling and lead time Site location and mobilization: Location, travel, and access coordination affect the total project cost We do not publish standard pricing because project conditions vary too much to make a price list useful. Contact us with your project details and we will discuss what the scope realistically involves.
