“…These locations were selected to cover the range of shoreline types present at each site and were used for testing of remote sensing-based mapping research (Demers et al, 2013). The dominant substrate type and soil moisture were characterized at each location, and GPS locations and ground photos were recorded.…”

“…Ongoing research mapping shoreline types using both radar and optical information has proved quite useful. While the research presented here focuses on videography-based shoreline mapping, related work within the eSPACE project has focused on shoreline mapping using EO data produced through manual interpretation (e.g., Demers et al, 2013). Geotagged videos from aircraft and watercraft can also provide very high spatial resolution data capable of distinguishing finer substrate types that may become indistinguishable or easily confused at lower resolutions.…”

Mapping coastal information across Canada's northern regions based on low-altitude helicopter videography in support of environmental emergency preparedness efforts. Journal of Coastal Research, 31(2), 276-290. Coconut Creek (Florida), ISSN 0749-0208.In the face of increasing economic opportunities in Canada's northern regions, the need to improve our state of preparedness for oil spill-related emergencies is critical. While significant efforts have been put toward documenting baseline coastal information across Canada's southern regions, there is a large information gap regarding Arctic shorelines. Baseline coastal information, such as shoreline form, substrate, and vegetation type, is required for prioritizing operations, coordinating onsite spill response activities (i.e. Shoreline Cleanup Assessment Technique [SCAT]), and providing information for wildlife and ecosystem management. Georeferenced high-definition videography was collected during the summers of 2010 to 2012 along coastlines within six study sites across the Canadian Arctic. Detailed information describing the upper intertidal, supratidal, and backshore zones was extracted from the video and entered into a geospatial database using a data collection form. This information was used to delimit and map alongshore segments in the upper intertidal zone. Almost 15,000 km of northern shorelines were mapped, including 25 shoreline types based on the upper intertidal zone. This information will feed into a larger ongoing project focused on Arctic coastal ecosystems and oil spill response planning should the need arise.

“…A quantification and monitoring of Arctic vegetation is of interest with respect to the estimation of the carbon stock and the carbon flux [4,5,29]. Beside this information on coverage is of interest for assessment in case of oil disasters [30,31].…”

Land Cover Characterization and Classification of Arctic Tundra Environments by Means of Polarized Synthetic Aperture X- and C-Band Radar (PolSAR) and Landsat 8 Multispectral Imagery — Richards Island, Canada

Abstract:In this work the potential of polarimetric Synthetic Aperture Radar (PolSAR) data of dual-polarized TerraSAR-X (HH/VV) and quad-polarized Radarsat-2 was examined in combination with multispectral Landsat 8 data for unsupervised and supervised classification of tundra land cover types of Richards Island, Canada. The classification accuracies as well as the backscatter and reflectance characteristics were analyzed using reference data collected during three field work campaigns and include in situ data and high resolution airborne photography. The optical data offered an acceptable initial accuracy for the land cover classification. The overall accuracy was increased by the combination of PolSAR and optical data and was up to 71% for unsupervised (Landsat 8 and TerraSAR-X) and up to 87% for supervised classification (Landsat 8 and Radarsat-2) for five tundra land cover types. The decomposition features of the dual and quad-polarized data showed a high sensitivity for the non-vegetated substrate 8566(dominant surface scattering) and wetland vegetation (dominant double bounce and volume scattering). These classes had high potential to be automatically detected with unsupervised classification techniques.
