AbstractNatural 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. The Mer Bleue Bog Peatlands, a conveniently accessible sub-arctic wetland similar to wetlands found in the Arctic environment, is being used as 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. Precisely 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 multi-spectral imagery acquired within the scope of MBASSS during 2016.
Summary(Plain Language Summary, not published)
The Arctic is an important, but difficult, area to study for wetland monitoring. To reduce survey costs, researchers often use more accessible surrogate sites. Ontario's Mer Bleue Bog, featuring open space / low tree coverage, typical of Arctic environment, is used here as Arctic surrogate study site. For the last few years, versatile and low cost Unmanned Aerial Vehicles (UAV's), commonly known as drones, have been used for multi-temporal aerial surveys of wetlands. The geographic positioning of the UAV data is often insufficient to support a proper survey. This open file describes in detail the methodology and results of a ground GPS survey used for the geographic correction of the UAV photo data collected over Mer Bleue Bog in 2016.
