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).**

This dataset was developed to document the procedures for acquiring underwater images in the Banc-des-Américains Marine Protected Area (MPA). Its primary objective is to provide a comprehensive inventory of metadata linked to imagery campaigns that allowed us to conduct a basic characterization of the area, and now that are used for ecological monitoring of the benthic habitats within the MPA.Metadata were collected during imagery surveys conducted since 2012, using three main methods: drop cameras on the crest, baited drop stereoscopic cameras on both the crest and plains, and towed cameras on the plains. For each operation are shared the type of gear used, sampling method, date, geographic coordinates, and acquisition depth.The released dataset contains only descriptive information related to the acquisition of images : file identifier, location, sampling methodology, depth, and technical imaging parameters. It does not include image files themselves, visual content, or the results of image analyses.A systematic quality control is applied to ensure completeness and consistency of the metadata: field format standardization, validation of GPS coordinates, verification of dates and recorded depths. Clear instructions guide the recording of metadata to guarantee their reliability for management and scientific monitoring purposes.

All available bathymetry and related information for Bonnie Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

All available bathymetry and related information for Lac Ste. Anne were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

All available bathymetry and related information for Iosegun Lake were collected and hard copy maps digitized where necessary.

This collection is a legacy product that is no longer supported. It may not meet current government standards.This inventory presents chronologically the satellite images acquired, orthorectified and published over time by Natural Resources Canada. It is composed of imagery from the Landsat7 (1999-2003) and RADARSAT-1 (2001-2002) satellites, as well as the CanImage by-product and the control points used to process the images.Landsat7 Orthorectified Imagery: The orthoimage dataset is a complete set of cloud-free (less than 10%) orthoimages covering the Canadian landmass and created with the most accurate control data available at the time of creation.RADARSAT-1 Orthorectified Imagery: The 5 RADARSAT-1 images (processed and distributed by RADARSAT International (RSI) complete the landsat 7 orthoimagery coverage. They are stored as raster data produced from SAR Standard 7 (S7) beam mode with a pixel size of 15 m. They have been produced in accordance with NAD83 (North American Datum of 1983) using the Universal Transverse Mercator (UTM) projection. RADARSAT-1 orthoimagery were produced with the 1:250 000 Canadian Digital Elevation Data (CDED) and photogrammetric control points generated from the Aerial Survey Data Base (ASDB).CanImage -Landsat7 Orthoimages of Canada,1:50 000: CanImage is a raster image containing information from Landsat7 orthoimages that have been resampled and based on the National Topographic System (NTS) at the 1:50 000 scale in the UTM projection. The product is distributed in datasets in GeoTIFF format. The resolution of this product is 15 metres.Landsat7 Imagery Control Points: the control points were used for the geometric correction of Landsat7 satellite imagery. They can also be used to correct vector data and for simultaneously displaying data from several sources prepared at different scales or resolutions.
