Note that topographic maps at a scale of 1/100,000 are no longer updated.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...

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 Forest Protection Department of the Ministry of Natural Resources and Forests has produced a matrix layer representing the potential for the intensity and spread of forest fires in Quebec. This data is the result of the annual analysis of the distribution of forest fuels at a local...

The data presented on this page concern the 2020-2022 mapping of temperature differences, the classification maps of these temperature differences (i.e. urban heat and freshness islands) and the map of the urban heat island intensity index. These different maps are detailed below: - The mapping...

The data presented on this page concern the 2013-2014 mapping of temperature differences, the classification maps of these temperature differences (i.e. urban heat and freshness islands) and the map of the urban heat island intensity index. These different maps are detailed below: - The mapping...

Warning The 2012 version of Urban Heat/Freshness Islands and Surface Temperature is now replaced by a newer version from 2013-2014 and 2020-2022. Data from the 2012 version is archived on Data Québec for consultation, for example for old reports or analyses referring to this version of the data....

Maps of the analysis of change between * [mapping of heat islands/freshness 2020-2022] (https://www.donneesquebec.ca/recherche/dataset/ilots-de-chaleur-fraicheur-urbains-et-ecarts-de-temperature-relatifs-2020-2022) * and * [mapping of heat/freshness islands using 2013-2014 data]...

Note that topographic maps at a scale of 1/20,000 are no longer updated. For the latest update date, see the [metadata] (ftp://transfert.mern.gouv.qc.ca/public/diffusion/RGQ/Documentation/BDTQ/Metadonnees_Topo-20K.xls). The reference cartographic data is now constituted according to a continuous...

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...

An accurate representation of the relief is essential for a large number of land management applications. Digital terrain models (DTM) and digital surface models (MNS) are simplified representations of ground altimetry. The MNT is a representation of the altitude of “bare ground” without...

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 numerical canopy model (MNC) is a representation of the altitude of the canopy. This 3D representation of the arboreal vegetation corresponds to the 2015 2D canopy. If necessary, the MNC can be coupled with the [Numerical Surface Model (MNS)] (/city-of-montreal/numeric-surface-model) 2015 in...

The theme of land use at the origin of these layers is a value-added product created from the assembly of geographic data that must respect various use and distribution agreements. The degree of accuracy of this product corresponds to the precision of the layers that compose it. To access the...

The geographic data from the land accounts of southern Quebec correspond to a set of matrix files with a spatial resolution of 50 meters, qualifying at three distinct times the type of land cover of Quebec territory located south of the 51st parallel. These geospatial data are those used in the...

The purpose of the cartographic data resulting from analyses of the ecological connectivity of natural environments in the St. Lawrence lowlands is to equip users by making it possible to integrate the concepts of ecological connectivity and the quality of the habitat of natural terrestrial...

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...
