Note that topographic maps at a scale of 1/100,000 are no longer updated. For the latest update date, see the [metadata] (ftp://transfert.mern.gouv.qc.ca/public/diffusion/RGQ/Documentation/BDAT/Metadonnees_BDAT100k_NordSud.xls). The reference cartographic data is now constituted according to a...

Peatlands include information relating to peatlands defined as a wetland, colonized by vegetation allowing the formation of a soil made of peat that is the result of the fossilization of organic matter.This third party metadata element was translated using an automated translation tool (Amazon...

The canopy is defined by the projection on the ground of the tops (crown) of trees (including leaves, branches, and trunks), which is visible from the sky. Any vegetation with a height greater than 2 m was taken into account. The mapping of the canopy was carried out using deep learning methods,...

TOPEX (acronym which means “topographical exposure”) is an index of topographic exposure. It reflects the influence of local topography on the degree of exposure to wind and on its behavior (Ruel et al. 2002). TOPEX data are presented in the form of a matrix file (raster) whose spatial resolution...

Cartography of the vegetation cover of Quebec City. The canopy represents the projection on the ground of the tops (crown) of trees (including leaves, branches, and trunks), which is visible from the sky. The data comes from an automated classification of two satellite images covering Quebec City...

Topographic mapping of northern indigenous villages is available for 23 villages. It was produced by photogrammetric method, from aerial photographs taken between 2009 and 2011. The accuracy of this mapping is of the order of ±40 centimeters in planimetry. In hypsometry, it is ±50 centimeters for...
