Description

Orthorectified imagery (orthophotographs and orthomosaics) offers an aerial view of Quebec territory at different times. Orthophotographs are the result of a process that corrects the deformations caused by the inclination of the camera and the relief. Orthomosaics are the fusion of several orthophotographs that facilitate analysis on a larger scale. Acquired since 1992, orthorectified imagery offers a faithful representation of the territory at various dates. In particular, it can be used for mapping, territorial planning, monitoring landscape changes, environmental risk analysis or integration into geographic information systems (GIS) by a variety of stakeholders, including professional staff from municipal, governmental, governmental, forestry, agricultural and environmental communities, including professional staff from municipal, governmental, governmental, forestry, agricultural and environmental communities. The geographic coverage and technical characteristics (resolution, product type) are accessible via the [download map] (https://imagerie-telechargement.portailcartographique.gouv.qc.ca/), which also allows files to be retrieved. This coverage will be improved regularly depending on the availability of new data. These collections come from several government initiatives, including the Ecoforest Inventory of Southern Quebec (IEQM), and numerous partnerships with ministries, agencies and municipalities. In addition, orthophotographs produced as part of the planning, monitoring and control of forest activities are also available, only in visualization mode, on [Forêt Ouverte] (https://www.foretouverte.gouv.qc.ca/?pos=@-74.03258,49.08077&ctx=_default&urls=https://servicesmatriciels.mern.gouv.qc.ca/erdas-iws/ogc/wmts/Imagerie_Aeroportee_Forestiere_Historique&layers=0,[Planification_Suivi_Controle_2023_2023_Planif_Suiv_Cont_20cm_)**This third party metadata element was translated using an automated translation tool (Amazon Translate).**
