Satellite Imaging Project Samples

Remote Community Orthophotography and Planimetry

nunavut2.JPG

Aeroquest Mapcon was contracted to provide 50 cm resolution colour orthophotography and 3D planimetric collection for several remote northern communities.

  • 50 cm resolution 3-band (RGB) orthophotography

  • New DEM photogrammetrically collected in 3D from stereo pairs

  • Additional planimetric collection included buildings, hydrology, infrastructure and transportation

  • Project included surveyed targeted ground control

  • Total project area of approximately 650 km²

  • Imagery sourced from WorldView-2

Pacific Northwest Orthophotography

Aeroquest Mapcon was contracted to provide 50 cm resolution colour orthophotography over a project area in northwest Washington State.

  • Project area 577 km²

  • Imagery was rectified using existing NAIP DEM

  • Orthophotography was controlled using existing higher resolution rectified imagery

  • Imagery sourced from WorldView-2

Western Africa Orthophotography

Aeroquest Mapcon was contracted to provide high resolution 30 cm satellite orthophotography for a project area located in Burkina Faso.

  • Project area 483 km²

  • Imagery was rectified using existing SRTM DEM

  • Orthophotography was controlled using the satellite ephemeris data

  • Imagery was sourced from WorldView-3

Satellite Imagery Based Photogrammetric Bathymetry

Aeroquest Mapcon was contracted to provide bathymetric maps of several northern lakes using satellite imagery.

  • 50 cm WorldView-2 stereo imagery was acquired for approximately 1015 km²

  • Coastal blue, Blue and Green spectral bands were used for maximum water penetration

  • Both ephemeris data and ground control was used to increase imagery positioning and stereo accuracy

  • The lake bottom elevations were manually collected in 3D stereo as contour data and used in conjunction with the collected lake shore perimeter to calculate water volumes

  • Final results were compared to previous traditional bathymetric surveys performed in the same lakes to determine accuracy and cost effectiveness of different methodologies

Northern Community SAR Imagery

This Capella SAR satellite imagery was captured in the north and shows both the community and surrounding rivers.

  • 60 cm SAR imagery

  • Captured project area is approximately 50 km²
