| Abstract | 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 Vehicule (UAV) platforms.
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.
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
Vehicule photographs, acquired within the scope of this project in Mer Bleue bog in 2015. |
| 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. The Mer Bleue Bog is used as an arctic surrogate site, featuring open space and low tree coverage, typical of Arctic environment. For the last few years, versatile and low cost Unmanned Aerial Vehicles (UAV's), 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. This document describes the method and results of the GPS survey used for the geographic rectification of numerous photographs acquired by UAVs. The study should result in
more accurate and precise UAV surveys and improved multi-temporal monitoring in the Arctic and other regions. |
