ASL Remote Sensing

Research and Development

At ASL Borstad Remote Sensing we specialize in custom data analysis.  A sampling of possible analyses includes:

Leading from our early involvement in satellite oceanography and high-resolution spectroscopy, we have been centrally involved in the development of several airborne instruments, particularly of high spectral resolution 'imaging spectrometers'. We are proud to say that we are among the most experienced hyperspectral organizations anywhere. Since 1983, we have worked with five generations of airborne hyperspectral sensors. These include the IOS spectrometer, the Fluorescence Line Imager (FLI), the Compact Airborne Spectrographic Imager (CASI), which the company helped design, the Shortwave Infrared Full Spectrum Imager (SFSI) built by the Canada Centre for Remote Sensing, and the AISA Hyperspectral Imager from SPECIM in Finland. As well, we have developed the means to directly detect and count whales and seals using high spatial resolution digital cameras carried in aircraft and helicopters.

We have developed methods to use satellite image-maps of sea surface temperature, sediment concentration, sea ice, oceanographic fronts and other features to describe the ocean environment. These maps can then be used, for example, to help explain distribution of salmon fishing vessels off the BC coast, and bowhead whales in the Beaufort, the Chukchi, and the Bering Seas, and for ‘real-time’ distribution to research vessels.  In studies with Synthetic Aperture Radar from aircraft and satellites, we developed explanations for SAR ocean feature returns, including slicks, internal waves, navigational structures, vessels and their wakes.

Also, we have developed interpretation of satellite-based measurements of water colour to provide a climatology of ocean productivity on the British Columbia and Newfoundland coasts. We have worked with fisheries managers to relate primary production with the survival of commercially harvested fish species.

We have developed preprocessing and analytical methods, and geological and safeguards applications of imagery from the hyperspectral imager HYPERION.  Recently we have begun to explore the interpretation of time series data from moored acoustic devices using image analysis techniques.  Please browse our publication list for a sampling of past research projects.
