Topographic maps at a scale of 1:20,000

**Note that topographic maps at a scale of 1:20,000 are no longer updated. For the last update date, see [metadata] (ftp://transfert.mern.gouv.qc.ca/public/diffusion/RGQ/Documentation/BDTQ/Metadonnees_Topo-20K.xls). The reference cartographic data is now constituted using 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)] (https://www.donneesquebec.ca/recherche/fr/dataset/decoupages-administratifs) * [Hydro coherent numerical terrain models at the regional scale (MNT)] ( 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 form the official cartographic basis of the Government of Quebec. They cover almost the entire 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 the rated 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 infrastructures (roads, bridges, airports, etc.); * buildings (mobile homes, silos, greenhouses, etc.); * equipment (docks, electric power transmission lines, surface reservoirs, etc.); * equipment (docks, electric power transmission lines, surface reservoirs, etc.) etc.); * designated areas (golf courses, loanbanks, etc.) * The relief (the contour lines are generally at an equidistance of ten meters 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).**
