  • The 1 cm resolution digital surface model (DSM) was created from unmanned aerial vehicle (UAV) imagery acquired from a single day survey, July 28th 2016, in Cambridge Bay, Nunavut. Five control points taken from a Global Differential Positioning System were positioned in the corners and the center of the vegetation survey. The DSM covering 525m2 was produced by Canada Centre for Remote Sensing /Canada Centre for Mapping and Earth Observation. The UAV survey was completed in collaboration with the Canadian High Arctic Research Station (CHARS) for northern vegetation monitoring research.

  • This map presents the history of the political boundaries in Canada, from Confederation in 1867 to 2017. Canada’s boundaries are dynamic political structures that reflect the changing political, economic, and cultural conditions of the country through time. Canada’s long and diversified settlement history is reflected in the two distinct patterns of boundaries that differentiate eastern and western Canada. In the east, the evolution of the Atlantic provinces’ boundaries are the outcome of 200 years of colonial competition for both land and resources. Similarly, Quebec and Ontario grew from frontier settlements to industrialized economies between 1760 and the early 1900s. As well, in the boundaries of eastern Canada closely conform to natural features such as drainage basins. In contrast, the boundaries of western and northern Canada reflect the administrative organization of these lands by, first, the Hudson’s Bay Company and, later, the Government of Canada. Here, geometric lines radiate northward from the 49th parallel, creating boundaries that often divide communities and regions into two different provincial jurisdictions. Each of the western provinces has a unique history and rationale for their boundaries. Manitoba evolved from the first Riel Rebellion as a "postage stamp" province, and only later achieved its present-day boundaries. Alberta and Saskatchewan earned provincial status with an eye to creating equal land areas. On the Pacific coast, the British colonies had to act quickly in response to the explosive gold mining frontier to organize and solidify their territorial claims to present-day British Columbia, and later to help establish the Yukon Territory in response to American encroachment. In the North, the boundaries of the existing Territories were redrawn in 1999 to create Nunavut. The boundaries of this new territory respect the traditional Aboriginal concept of territoriality. This online interactive map relies on the emerging "MapML" standard co-developed by Natural Resources Canada. The objective of this evolving standard is to make it simple for beginners and experts alike to create maps in Web pages that use open data and map services.
