Prévost, H.P. White. [Ottawa] : Natural Resources Canada, 2016. 59 p. : col. ill., col. maps. Open file ; 29 Includes bibliographical references. "Natural Resources Canada (NRCAN) has the mandate of providing essential geographic information. An improved knowledge of our physical environment represents one of the basis of 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; this is why the Mer Bleue Bog, featuring open space / low tree coverage, typical of Arctic environment, is used as arctic surrogate study site. This study site is used for the calibration - validation of various types of remote sensing data acquired by several project partners, and using satellite, airborne and Unmanned Aerial Vehicle (UAV) platforms. Precisely geo-located 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. This document, highly illustrated, describes in detail the method and results of the GPS survey required for the geographic rectification of the numerous types of imagery, including Unmanned Aerial Vehicle photographs, acquired within the scope of this project in Mer Bleue Bog in 2015”--Abstract, p. 5. gccst Wetlands gccst Geographic data gccst Global positioning systems gccst Remote sensing White, H.
