  • Digital terrain models provide a representation of the relief south of the 52nd parallel, in the form of an elevation matrix. This matrix allows you to visualize the territory in perspective and perform three-dimensional spatial analysis using the appropriate software. A module specialized in processing three-dimensional data, such as 3D Analyst or Spatial Analyst, is required to visualize the three-dimensional elevation numerical model. This numerical elevation model (10 meter pixel matrix) is obtained by processing altimetric data (level curves and elevation points) from [1/20,000 scale topographic databases] (https://www.donneesquebec.ca/recherche/fr/dataset/cartes-topographiques-a-l-echelle-de-1-20-000). **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

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

  • Data on the recreational territories of Quebec are compiled from official technical plans and descriptions, and entered on topographic mapping at a scale of 1:100 ,000. Data update is usually done once a year. Main Components: * Community Wildlife Areas (CFA); * Specific Agreements with Aboriginal Peoples; * Small Developed Lakes (PLA); * Outfitting with exclusive rights; * Exclusive Hunting Territories; * Wildlife Reserves; * Controlled Use Areas (ZECs); * Quebec National Parks; and Canada National Parks; * Regional Parks; * Marine Parks; * Ecological reserves; * Wildlife sanctuaries; * Migratory Bird Sanctuaries (MBS); * National Wildlife Areas; * Montmorency Education and Research Forest; * Duchesnay Forest Station. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • **Note that topographic maps at a scale of 1/20,000 are no longer updated. For the last update date, see the [metadata] (ftp://transfert.mern.gouv.qc.ca/public/diffusion/RGQ/Documentation/BDTQ/Metadonnees_Topo-20K.xls). The reference map data is now based on a continuous information layer approach: ** * [AQNetwork+] (https://www.donneesquebec.ca/recherche/fr/dataset/adresses-quebec) * [Quebec Hydrographic Network Geobase (QHRM)] (https://www.donneesquebec.ca/recherche/dataset/grhq) * [Administrative splits at scale of 1/20,000 (SQ) DA)] (https://www.donneesquebec.ca/recherche/fr/dataset/decoupages-administratifs) * [Models Regional coherent hydro terrain numerical (NTM)] (https://www.donneesquebec.ca/recherche/fr/dataset/modeles-numerique-de-terrain-hydro-coherents-a-l-echelle-regionale) *** Topographic maps at a scale of 1/20,000 are the official cartographic base of the Government of Quebec. They cover almost the entire territory south of the 52nd parallel. The data are extracted from aerial photographs at a scale of 1/40,000 taken at an altitude of 6,300 metres. They offer an accuracy of approximately four meters in planimetry. In hypsometry, it is about two meters for the quoted points and about five meters for the level curves. Each file covers an area of approximately 250 km2. The main components are: * Hydrography (lakes, rivers, streams, swamps, etc.) .* Vegetation (forests, peatlands, nurseries, orchards, etc.) .* Human constructions: * transport infrastructure (roads, bridges, airports, etc.); * buildings (mobile homes, silos, greenhouses, etc.); * equipment (docks, power transmission lines, etc.) * Designated areas (golf courses, borrowing benches, etc.) * Relief (level curves are usually at an equidistance of ten meters and in some cases they may vary between eight and twenty metres). **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • The product of the land rights layer (leases) contains the centroid or, in some cases, the outline of leases granted by the Government of Quebec, or granted by the RCMs and cities that have signed an agreement to delegate land management and the management of sand and gravel exploitation on lands in the domain of the Crown. The main components are: * Personal use (e.g., principal residence, cottage, summary forest shelter) * Commercial purpose (e.g., outfitting, tourist site, fish farming, sawmill) * Public purpose (e.g., telecommunications) * Municipal purpose (recreational or sporting activities) * Community purpose (shelter, shelter, lodge, trail) According to in the case, the data sources are: * GPS seizures * Aerial photographs* Survey surveys **This third party metadata element was translated using an automated translation tool (Amazon Translate).**
