__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...

This map illustrates the terrestrial and marine reliefs of Quebec and surrounding territories, at a scale of 1/2,000,000. Color ranges representing altitude classes and blending offer a summary of the relief and the major physiographic groups of Quebec. This map of the relief of Quebec is...

The bank of oblique photographs of Northern Quebec is composed of georeferenced photos taken on board planes or helicopters during flights carried out as part of the program for the acquisition of ecological knowledge in Northern Quebec as part of the economic, social and environmental...

The temporary sample plot is a circular sample unit that covers an area of 400 m2. For each tree, we observe and measure the species, diameter, sunlight, and floor in relation to other trees, as well as the defoliation and the quality of the stems of deciduous trees and certain pines. In...

Being eager to participate in the adaptation of agricultural businesses in a context of climate change, MAPAQ commissioned the conduct of a study to better identify the current and future challenges of water management. The mandate involved drawing up a portrait of the water needs at the regional...

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,...

The link: Access the data directory is available in the sectionDataset Description Sheets; Additional Information. Formerly, forest maps were produced by the Land Survey Department of the Ministry of Lands and Forests. Some of these maps dating from 1924 to 1946 still exist and are carefully...

__The link: * Access the data directory is available in the sectionDataset description sheets; Additional information__. The ecoforest inventory north of the northern limit of attributable forests is an extensive inventory that was carried out for specific knowledge acquisition needs. It was...

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 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...
