Aerial Imagery

Harrier Aerial Surveys specializes in aerial imagery taken from unmanned aerial vehicles (UAV) commonly called drones. UAV have the capability to fly at lower altitudes than full-sized aircraft filling a gap between traditional on-ground surveying and using full-sized aircraft.


Harrier has both fixed-wing and multi-rotor unmanned aerial vehicles in its arsenal to help you get the best aerial imagery for your project.


Fixed-wing craft have long flight times, are efficient and can carry multiple sensors. Multi-rotor craft have a perch and stare capability, are more maneuverable and can capture both video and still photography.

Nadir Orthophotography

The majority of the aerial imagery that Harrier Aerial Surveys captures is nadir, straight down, allowing us to stitch multiple photographs together to form one high resolution mosaic of the target.

Through our processing we are then able to produce orthophotos, an image mosaic where each pixel is represented as it would be seen when looking straight down. These orthophotos are also georeferenced for use in GIS and Mapping.



We also capture oblique imagery when the client need is for visual inspections or vertical surface construction.

Surface construction from aerial imagery is performed using a technique called modern photogrammetry, where images of the same target from different perspectives are used to determine target depth.

With high resolution cameras thousands of targets can be identified in each image resulting in a dense three dimensional point set.

Harrier Aerial Surveys, using these methods of aerial imagery, collects more data, more efficiently, and with higher accuracy than traditional methods.

We’d love to help you on your next project. Give us a call or send us an email to see if we can help you with your next surveying project.

We’ve worked as far abroad as Fiji and on many locations in our home province of British Columbia.

From mining to pulp mills, our client list is a long and happy one.
