Airborne Survey Platforms & Sensors

Aeroquest Mapcon has been performing manned aerial surveys since 1987. As imaging technology has evolved and become available over the years, we have embraced the new image platforms and capabilities to offer our clients the latest in products and solutions to their mapping needs.

Aircraft

  • quick response time

  • relative low cost

  • 5 cm - 30 cm resolution

  • LiDAR Acquisition (2 pts/sq. m - 30+ pts/sq. m)

  • medium to large areas (1 square km +)

Constituting a large majority of our acquisition, aerial photography/LiDAR from aircraft is the primary source of imagery for many of our clients. Aircraft response time, relatively low cost, the ability to cover large areas, and high resolution capabilities provides many of our clients with the aerial survey needs they require. Aeroquest Mapcon, along with our acquisition partners, has access to a variety of image sensors in locations across North America. The latest digital sensors provide exceptional resolution, high bit depth and the ability to capture multiple bands. Aeroquest Mapcon's expertise in acquiring and processing aerial photography from aircraft has allowed us to successfully complete projects including but not limited to high and low density urban areas, forestry, energy and mining, desert, shoreline, far north and mountainous projects.

Satellite

  • multi-spectral (3 - 16 bands)

  • > 30 cm resolution

  • large areas (> 100 square km)

Aeroquest Mapcon has been providing satellite surveys to government and commercial clients since 2007. Having developed partnerships with several imaging platforms allows Aeroquest Mapcon to provide imagery from various suppliers such as Digital Globe, Airbus and Deimos to meet the precise imaging needs of our clients at the best price. For clients that need to cover areas with >30cm resolution imagery, require the additional imagery bands, or need imagery in remote locations, satellite platforms can be the right choice for their project. Aeroquest Mapcon can acquire the needed imagery and generate a full array of base map products such as orthophotography, digital elevation models and planimetry to meet our clients' needs.

UAV

  • quick response time

  • 0.5 cm - 5 cm resolution

  • PhoDAR (30 pts/square m - 500+ pts/square m)

  • small areas (under 1 square km)

Aeroquest Mapcon has been providing Unmanned Aerial Surveys to government and commercial clients since 2014. Our ability to get the appropriate permits, mobilize, acquire, and generate 3-D mapping products is unmatched in the industry due to our extensive experience in providing aircraft acquired aerial survey projects. We have standing (blanket) SFOCs (Special Flight Operations Certificates) for large parts of western and northern Canada allowing us to capture your project imagery soon after flight planning and without the lengthy delays of waiting for permits. For clients that require a small or very specific area to be mapped at very high resolution, utilizing a UAV imaging platform can provide excellent results. The products generated from a UAV aerial survey include orthophotos and point clouds. 

 


SENSORS

Aeroquest Mapcon utilizes a variety of sensors for capturing aerial imagery and LiDAR elevation data.

Vexel Ultracam Digital Aerial Cameras

  • 136MP, 261MP or 450MP 16-bit imagery

  • 4-band (R,G,B,NiR) capability

  • 80mm & 100mm focal lengths

  • Camera & boresite calibrations performed regularly

 

Leica DMC III Aerial Camera

  • 375MB 16-bit imagery

  • 4-band (R,G,B,NiR) capability

  • 92mm lens

  • Camera & boresite calibrations performed regularly

 

Phase One Camera

  • 80MP medium format digital camera

  • Useful for small areas flown at a lower altitude

  • Mountable on fixed wing aircraft or helicopter platforms

 

Riegl Q1560 LiDAR

  • 2 offset lasers allows for better penetration through vegetation than conventional LiDAR scanners

  • Vertical Accuracy on hard surfaces +/- 10cm

  • 60-degree field of view

  • highly suited for aerial surveys of ultra-wide areas as well as complex urban environments and rugged terrain

 

Airborne GPS (AGPS) and Inertial Measurement Unit (IMU)

  • Airborne GPS and IMU are used with all sensors and on all projects

  • Airborne GPS utilizes satellite positioning to provide an accurate, cost effective and rapid method of providing control and ensures accuracy of photo center positions.

  • IMU uses extremely sensitive motion-sensing technology to record any change in aircraft orientation (roll, pitch, yaw).

  • AGPS data together with IMU data can reconstruct the exact position of the aircraft during image exposure and use this information as part of the aerial triangulation solution.

  • In inaccessible areas without ground control, AGPS and IMU can be used to often achieve sub-metre data accuracy.
