Deposit is the layer of loose material that covers rock. It may have been established during the retreat of the glacier at the end of the last glaciation or by other processes associated with erosion and sedimentation. The nature of the loose deposit is evaluated based on the shape of the land,...

Permafrost is any soil or rock whose temperature has remained below 0°C for years. In the extreme north of Quebec, it is omnipresent and very thick. At its boreal margin, further south, it appears in the landscape in the form of isolated thin plates, whose thickness is generally less than 10 m....

These digital terrain models (DTM) offer a regional numerical representation of Quebec's relief based on altimetric (altitude) and planimetric (rectangular or geographic) data. They are the result of a collaboration between the Ministry of Natural Resources and Forests (MRNF) and Natural...

The ecological classification of Quebec territory consists of mapping and describing ecological units in a system with nine levels of perception between the continental and landscape scales. It presents the diversity of terrestrial ecosystems in all of Quebec taking into account both the...

This theme represents the limit of the Quebec territory of the Agreement on Sustainable Water Resources of the Great Lakes and St. Lawrence River Basin. It was generated from the grouping of watersheds at a cartographic scale of 1:20,000. For more information:...

The level curves are derived from a LiDAR survey carried out in May 2014. The equidistance is 25 cm, the absolute planimetric accuracy (XY) is approximately 40 cm, and the absolute altimeter accuracy (Z) is approximately 20 cm. The urban sectors covered are the urban areas of Rouyn, Noranda,...

The SiIGsol-100m maps make it possible to document the spatial evolution of the properties of the mineral part of the soil at a spatial resolution of 100 m. These values were simulated by combining point observation data and spatially explicit covariates, derived from remote sensing data, using...

__The link: * Access the data directory is available in the sectionDataset description sheets; Additional information. Ecoforest maps in PDF format are available at a scale of 1/20,000 and cover Quebec territory approximately up to the 52nd parallel. Each map covers an average area of...

Digital terrain models offer a representation of the relief south of the 52nd parallel, in the form of an elevation matrix. This matrix makes it possible to visualize the territory in perspective and to perform three-dimensional spatial analyses, using appropriate software. A module specialized...

From 1986 to 2000, a major ecological inventory program was carried out in the forests of southern Quebec in order to describe the diversity of forest ecosystems. In total, 28,425 ecological observation points (POE) were established on a territory covering 760,000 km2, located between 45° and 53°...

Since 1 March 2022, the Special Intervention Zones (ZIS) have been lifted. However, the territory flooded during the exceptional spring floods of 2017 and 2019, as illustrated in Annex 2 adjusted to Decree 814-2019, is considered by the Regulation concerning the provisional implementation of the...

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...
