Geographic and administrative database

Geographic and administrative database The Geographic and Administrative Database is available at scales of 1/1,000,000 (BDGA1M) and 1/5,000,000 (BDGA5M). It provides a geographic and administrative base on a small scale for the whole of Quebec. The data is the result of an automatic generalization of the vectors of a database on a scale of 1/250,000, and from a geometric and thematic purification. Data from territories outside Quebec must be used and considered with some reservations, taking into account the date they were updated and the classifications used. Administrative boundaries also come from the generalization of data at a scale of 1/250,000 on major hydrographic axes. This database brings together: * Major hydrographic complexes; * Transport and hydroelectric infrastructures; * The main agglomerations and centers of occupation; * The limits of major administrative divisions. For more information on the various data layers, consult the physical data structure documents (scales of [1/1,000,000] (https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Documentation/BDGA_1M/Structure_physique_BDGA1M.pdf) or [1/5,000,000] (https://diffusion.mern.gouv.qc.ca/diffusion/RGQ/Documentation/BDGA_5M/Structure_physique_BDGA5M.pdf)).**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 Original metadata (https://www.donneesquebec.ca)HTML https://www.donneesquebec.ca/recherche/fr/dataset/1f2065a4-314f-4740-b091-43ac9e9e7019 History of changes in administrative divisionsPDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/SDA/Historique_des_modifications.pdf Physical data structure (1M)PDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDGA_1M/Structure_physique_BDGA1M.pdf Physical structure of the data (5M)PDF https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Documentation/BDGA_5M/Structure_physique_BDGA5M.pdf Planimetric data on a scale of 1/1,000,000SHP https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Vectoriel/Carte_Topo/Provincial/BDGA_1M(plani)/SHP/BDGA_1M(plani)_SHP.zip Administrative divisions on a scale of 1:1 000 000SHP https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Vectoriel/Theme/Provincial/BDGA_1M(adm)/SHP/BDGA_1M(adm)_SHP.zip Planimetric data on a scale of 1/5,000,000SHP https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Vectoriel/Carte_Topo/Provincial/BDGA_5M(plani)/SHP/BDGA_5M(plani)_SHP.zip Administrative divisions on a scale of 1/5,000,000SHP https://diffusion.mern.gouv.qc.ca/Diffusion/RGQ/Vectoriel/Theme/Provincial/BDGA_5M(adm)/SHP/BDGA_5M(adm)_SHP.zip WMS service (color/color with fading)WMS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wms/Cartes_Images?service=WMS&REQUEST=GetCapabilities&layers=BDGA-1M_Carte_Generale_Couleur_Estompage&legend_format=image/png&feature_info_type=text/plain WMS service (color/color with fading)WMS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wms/Cartes_Images?service=WMS&REQUEST=GetCapabilities&layers=BDGA-1M_Carte_Generale_Couleur_Estompage&legend_format=image/png&feature_info_type=text/plain WMTS service (color/color with fading)WMTS https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wmts/Cartes_Images?SERVICE=WMTS&REQUEST=GetCapabilities
