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 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 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 2018.
Summary(Plain Language Summary, not published)
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; this is why the Mer Bleue Bog, featuring open space / low tree coverage, typical of Arctic environment, is used as arctic surrogate study site. For the last few years, versatile and low cost Unmanned Aerial Vehicles (UAV), commonly known as drones, can be used for multi-temporal aerial surveys of wetlands. Precisely geolocated products require ground control points (reference points) which are visible to the camera of the platform and whose geographic location is known with precision. To fulfill this need, high precision GPS surveys are required. A case study was completed in Mer Bleue Bog. This document describes in detail, with many illustrations, the method and results of the GPS survey used for the geographic rectification of numerous photographs acquired by the UAV within the scope of this project.
