The Ontario Imagery Web Map Service (OIWMS) is an open data service available to everyone free of charge. It provides instant online access to the most recent, highest quality, province wide imagery. GEOspatial Ontario (GEO) makes this data available as an Open Geospatial Consortium (OGC) compliant web map service or as an ArcGIS map service. Imagery was compiled from many different acquisitions which are detailed in the Ontario Imagery Web Map Service Metadata Guide linked below. Instructions on how to use the service can also be found in the Imagery User Guide linked below.Note: This map displays the Ontario Imagery Web Map Service Source, a companion ArcGIS web map service to the Ontario Imagery Web Map Service. It provides an overlay that can be used to identify acquisition relevant information such as sensor source and acquisition date. OIWMS contains several hierarchical layers of imagery, with coarser less detailed imagery that draws at broad scales, such as a province wide zooms, and finer more detailed imagery that draws when zoomed in, such as city-wide zooms. The attributes associated with this data describes at what scales (based on a computer screen) the specific imagery datasets are visible.Available ProductsOntario Imagery OCG Web Map Service – public linkOntario Imagery ArcGIS Map Service – public linkOntario Imagery Web Map Service Source – public linkOntario Imagery ArcGIS Map Service – OPS internal linkOntario Imagery Web Map Service Source – OPS internal linkAdditional DocumentationOntario Imagery Web Map Service Metadata Guide (PDF)Imagery User Guide (Word)StatusCompleted: Production of the data has been completedMaintenance and Update FrequencyAnnually: Data is updated every yearContactOntario Ministry of Natural Resources, Geospatial Ontario, imagery@ontario.ca

This image service contains high resolution satellite imagery for selected regions throughout the Yukon. Imagery is 1m pixel resolution, or better. Imagery was supplied by the Government of Yukon, and the Canadian Department of National Defense. All the imagery in this service is licensed. If you have any questions about Yukon government satellite imagery, please contact Geomatics.Help@gov.yk.can. This service is managed by Geomatics Yukon.

Note: To visualize the data in the viewer, zoom into the area of interest. The National Air Photo Library (NAPL) of Natural Resources Canada archives over 6 million aerial photographs covering all of Canada, some of which date back to the 1920s. This collection includes Time Series of aerial orthophoto mosaics over a selection of major cities or targeted areas that allow the observation of various changes that occur over time in those selected regions. These mosaics are disseminated through the Data Cube Platform implemented by NRCan using geospatial big data management technologies. These technologies enable the rapid and efficient visualization of high-resolution geospatial data and allow for the rapid generation of dynamically derived products. The data is available as Cloud Optimized GeoTIFF (COG) for direct access and as Web Map Services (WMS) or Web Coverage Services (WCS) with a temporal dimension for consumption in Web or GIS applications. The NAPL mosaics are made from the best spatial resolution available for each time period, which means that the orthophotos composing a NAPL Time Series are not necessarily coregistrated. For this dataset, the spatial resolutions are: 75 cm for the year 1960 and 50 cm for the year 1974. The NAPL indexes and stores federal aerial photography for Canada, and maintains a comprehensive historical archive and public reference centre. The Earth Observation Data Management System (EODMS) online application allows clients to search and retrieve metadata for over 3 million out of 6 million air photos. The EODMS online application enables public and government users to search and order raw Government of Canada Earth Observation images and archived product managed by NRCan such as aerial photos and satellite imagery. To access air photos, you can visit the EODMS web site: https://eodms-sgdot.nrcan-rncan.gc.ca/index-en.html

The Geomatics Division archives contain over 22,000 aerial photographs. The oldest date from 1930, but they are generally located between 1950 and 2003. The set provides a link to an interactive map allowing the download of aerial photographs from multiple years held by the City for the purposes of producing basic cartography. The images are available throughout the island of Montreal or partially depending on the years and scales of aerial photographs. An aerial photograph is a photograph taken from the air. Normally, these are taken vertically, on board an aircraft, using a highly accurate camera. NOTE1: The collection of the Geomatics Division is distinct from that of the Archives de Montréal. NOTE2: The City distributes the photographs in its possession. However, in the event that a claimant has claims on this subject, he is invited to submit them to the City. NOTE3: Note that for paper-based archival images, the City generally does not have the original slides. Refer to the index for details.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

View spatial imagery of Ontario captured by satellite or airplane. Background Every five years, the Ministry of Natural Resources coordinates projects to photograph high resolution imagery of settled areas of the province. Geospatial Ontario (GEO) acquires, maintains, and distributes this high-resolution imagery collected across Ontario. From 2013 to 2023, public and private sector organizations partnered with Ontario to share in the costs of acquiring aerial imagery. Project participants included: * other Ontario ministries * municipalities * federal agencies * conservation authorities * non-government organizations (NGOs) * private companies Starting in 2024, GEO will fully fund imagery acquisitions. All imagery will be released openly and available to everyone as soon as the imagery is ready as a mappable product. Technical information This record includes all collections of digital orthophotography which are currently open to the public. Collections are differentiated by year of acquisition and region of the province covered. Orthophotographs are primarily taken during the spring in leaf-off/low-leaf conditions. All orthophotography is available as GeoTIFFs with the following bands of spectral information: * red * green * blue * near-infrared Pixel size is consistent within collections but varies between collections, ranging from a minimum of 16 cm to a maximum of 50 cm. Open imagery access restrictions Starting in 2024, most orthophotography acquisitions will be made available under the Open Government Licence. This only applies to orthophotography collections where Ontario owns the intellectual property rights.

The Ontario Raw Point Cloud (Imagery-Derived) was created using a pixel-autocorrelation process based on aerial photography collected by the imagery contractor for the Geospatial Ontario (GEO) imagery program. The dataset consists of overlapping tiles in LAZ format and is 8.29 terabytes in size. Tiles for some projects are overlapping because the pixel-autocorrelation process extracts elevation values from overlapping stereo photo strips. No classification has been applied to the point cloud, however they are encoded with colour (RGB) values from the source photography.

For more detailed information about this dataset, refer to the associated User Guide.

For a product in non-overlapping tiles with a ground classification applied see the Ontario Classified Point Cloud (Imagery-Derived).

Raster derivatives have been created from the point clouds for some imagery projects. These products may meet your needs and are available for direct download. See the Ontario Digital Elevation Model (Imagery-Derived) for a representation of bare earth and the Ontario Digital Surface Model (Imagery-Derived) for a model representing all surface features.

Low-altitude (80-100 meters above ground level) digital images were obtained from a camera mounted on a 3DR Solo quadcopter, a small unmanned aerial system (UAS), along the Lake Ontario shoreline in New York during July 2017. These data were collected to document and monitor effects of high lake levels, including shoreline erosion, inundation, and property damage in the vicinity of Sodus Bay, New York. This data release includes images tagged with locations determined from the UAS GPS; tables with updated estimates of camera positions and attitudes based on the photogrammetric reconstruction; tables listing locations of the base stations, ground control points, and transect points; geolocated, RGB-colored point clouds; orthomosaic images; and digital elevation models for each of the survey regions. Collection of these data was supported by the Federal Emergency Management Agency, the State of New York Departments of State and Environmental Conservation, and the USGS Coastal and Marine Geology Program and was conducted under USGS field activity number 2017-042-FA.

Zoom in on the map above and click your area of interest or use the Tile Index linked below to determine which package(s) you require for download. The Digital Elevation Models (DEM) are 2-m resolution raster elevation products that were generated from the Ontario Classified Point Cloud (Imagery-Derived) data. The point clouds were created via a pixel-autocorrelation process from the stereo aerial photography of the Land Information Ontario (LIO) imagery program. It is important to note that the DEM does not represent a full ‘bare-earth’ elevation surface. There are areas where there are very few points classified as Ground and interpolation has occurred across the resulting voids. Points classified as Ground have not been assessed for accuracy to determine if they represent true ground features. Some features are still raised above ground surface, such as larger buildings, larger forest stands and other raised features.

For more detailed information about this dataset, refer to the associated User Guide.

Now also available through a web service which exposes the data for visualization, geoprocessing and limited download.

The service is best accessed through the ArcGIS REST API, either directly or by setting up an ArcGIS server connection using the REST endpoint URL. The service draws using the Web Mercator projection.

For more information on what functionality is available and how to work with the service, read the Ontario Web Raster Services User Guide. If you have questions about how to use the service, email Geospatial Ontario (GEO) at geospatial@ontario.ca.

The Forest Resource Inventory (FRI) is an extensive survey of the forest resources of Ontario. It was originally designed in 1946 to locate merchantable timber species for supplying mills.

Note: This data was updated in 2018 to group all blocks and boundaries together into four image services, organized by UTM zone. This provides more seamless and extensive coverage, and allows for easier downloads due to a significant and lossless reduction in the size of individual tiles.

The FRI was designed as a large-scale survey that would allow general characterization of the forest in terms of species, forest conditions and regeneration. Traditionally, the FRI has been based on aerial photo interpretation, as well as some field surveys.

This imagery will initially serve as a topographic reference base for any new output mapping and will serve as the source for subsequent base data production. The stereoscopic imagery will be used for softcopy photogrammetric application and interpretation. Imagery must be available but not restricted to multi-band colour, multi-band infrared and panchromatic.

The elevation data is required to support the generation of Digital Elevation Models (DEM) or Digital Surface Models (DSM) and subsequent derivative products in support of air photo interpretation, forest management planning and forest management operations.
