Topographic maps on a scale of 1/20,000

Topographic maps on a scale of 1/20,000 **Note that topographic maps at a scale of 1/20,000 are no longer updated.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 information layer approach: ** * [AQRéseau+] (https://www.donneesquebec.ca/recherche/fr/dataset/adresses-quebec) * [Geobase of the Quebec Hydrographic Network (GRHQ)] (https://www.donneesquebec.ca/recherche/dataset/grhq) * [Administrative divisions at the scale of 1/20,000 (SDA)] (SDA)] (https://www.donneesquebec.ca/recherche/fr/dataset/decoupages-administratifs) * [Geobase of the Quebec Hydrographic Network (GRHQ)] () * [Administrative divisions at the scale of 1/20,000 (SDA)] () * [Administrative divisions at the scale of 1/20,000 (SDA)] () * [Geobase of the Quebec Hydrographic Network (GRHQ)] () * [Administrative divisions at the scale of 1/20,000 (SDA)] ( 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 constitute the official cartographic base of the Government of Quebec. They cover almost all of the territory south of the 52nd parallel. The data is extracted from aerial photographs at a scale of 1:40,000 taken at an altitude of 6,300 meters. They offer an accuracy of approximately four meters in planimetry. In hypsometry, it is about two meters for dimensional points and about five meters for level curves. Each file covers an area of approximately 250 km2. The main components are: * Hydrography (lakes, rivers, streams, streams, swamps, etc.). * Vegetation (forests, peatlands, nurseries, orchards, etc.). * Human constructions: * transport infrastructures (roads, bridges, airports, etc.); * buildings (roads, bridges, airports, etc.); * buildings (mobile homes, silos, greenhouses, etc.); * equipment (docks, electric power transmission lines, surface reservoirs, etc.); * equipment (docks, electrical power lines, surface reservoirs, etc.).); * designated areas (golf courses, loan banks, etc.). * The relief (the contour lines are generally ten meters equidistant and, in in some cases, they may vary between eight and twenty meters).**This third party metadata element was translated using an automated translation tool (Amazon Translate).** 2025-05-01 Government and Municipalities of Québec geoboutique@mrnf.gouv.qc.ca Form DescriptorsNature and EnvironmentScience and Technology Download index (csv format)CSV https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/Index_BDTQ.csv Full directory (Cover format (ArcInfo))E00 https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Vectoriel/Carte_Topo/Local/BDTQ/ArcInfo/ Full directory (GeoTIFF format, MTM projection)GeoTIF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Matriciel/Carte_Topo/Local/BDTQ/GeoTIFFMTM/ Full directory (GeoTIFF format, CCL projection)GeoTIF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Matriciel/Carte_Topo/Local/BDTQ/GeoTIFFLCC/ Interactive mapHTML https://vgo.portailcartographique.gouv.qc.ca/mobile.aspx?gpz_point=-7409952.391302186,%206215035.784324403&echelle=8735660&epsg=3857&gpz_nomMap=-%20Carte%20topographique%2020k Download card per sheetHTML https://vgo-telechargement.portailcartographique.gouv.qc.ca/mobile.aspx?gpw=d6402295-a88c-452f-b8f5-6c17eb1c60a6 Original metadata (https://www.donneesquebec.ca)HTML https://www.donneesquebec.ca/recherche/fr/dataset/8dc04c10-708e-4afa-813e-acb96c3101a1 Index of map sheets (PDF format)PDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/couverture_20k_2009.pdf Full directory (PDF format)PDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Matriciel/Carte_Topo/Local/BDTQ/PDF/ Physical structure of the dataPDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/Structure_Topo-20K.pdf Production standardsPDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/Normes_Topo-20K.zip DGN file on a scale of 1/20,000PDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/DGN.pdf Legend of the topographic map on a scale of 1/20,000PDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/Legende_Topo-20K.pdf Additional coordinates for using raster imagesPDF https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Documentation/BDTQ/Tab_Tfw_Topo.pdf Download index (shp format)SHP https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/Index_BDTQ.zip WMS serviceWMS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wms/Cartes_Images?service=WMS&REQUEST=GetCapabilities&layers=BDTQ-20K&legend_format=image/png&feature_info_type=text/plain WMS serviceWMS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wms/Cartes_Images?service=WMS&REQUEST=GetCapabilities&layers=BDTQ-20K&legend_format=image/png&feature_info_type=text/plain WMTS serviceWMTS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wmts/Cartes_Images?SERVICE=WMTS&REQUEST=GetCapabilities MetadataXLS https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDTQ/Metadonnees_Topo-20K.xls Full directory (DGN format)other https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Vectoriel/Carte_Topo/Local/BDTQ/DGN/
