| Abstract | Natural Resources Canada (NRCan) has the mandate of providing essential geographic information. An improved knowledge of our physical environment represents one of the cores of this mandate. The Arctic
is an important but challenging region to study, especially for wetland monitoring. To reduce survey costs, researchers often use surrogate sites located in less remote areas when evaluating and developing applications. The Mer Bleue Bog Peatlands, a
conveniently accessible sub-arctic wetland similar to many wetlands found in the Arctic environment, is used as an arctic surrogate study site for the MBASSS Project.
This study site is used for the calibration and validation of various types of
optical (spectral) remote sensing data acquired by several project partners using satellite, airborne and Unmanned Aerial Vehicle (UAV) platforms. Precise geo-located products require ground control points (reference points) which are visible to the
sensor on the platform and whose geographic location is known with precision. To fulfill this need, high precision GNSS surveys are required.
This highly illustrated document describes in detail the methods and results of the GNSS surveys required
for the geographic rectification of imagery, including Unmanned Aerial Vehicle photographs, airborne hyperspectral imagery, and space borne multispectral imagery acquired within the scope of the Mer Bleue Arctic Surrogate Simulation Study (MBASSS)
during 2019. |
| Summary | (Plain Language Summary, not published)
Natural Resources Canada has the mandate of providing essential geographic information to Canadians. Advancing our knowledge of Canada's physical
environment is key for supporting this mandate. The Arctic is an important, but difficult, area to study especially for wetland monitoring. To reduce survey costs, researchers use surrogate sites located closer to home base office, such as Mer Bleue
bog, featuring open space / low tree coverage, typical of Arctic environment. Engineers, environmental scientist, and many others require detailed knowledge of the mechanisms associated with wetland (coverage, depth, and linkage with permafrost) for
scientific modelling and decision-making. To obtain this information, various process and methodologies must be used, including GPS surveys and new methodologies of aerial data acquisition and processing. |
