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.

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 Source Water Protection QuickBird Imagery Project constitutes a high-resolution satellite imagery data set for approximately 120,000 km2 in the Province of Ontario. This data consists of orthorectified image derivatives from the Level Basic-1B bundled imagery provided to the Ontario Ministry of Natural Resources (OMNR) by Digital Globe, Inc.

Pansharpened images (60 - 70 cm true colour composites) are required for mapping applications that require high-resolution background imagery. Additional image derivatives, such as enhanced Multispectral and Greyscale (Panchromatic) products (GeoTIFF and MrSID formats) may also be generated depending on requirements. Raw (Basic-1B) imagery was secured from Digital Globe to ensure that the orthorectification process could be conducted under the supervision of OMNR staff, with an adherence to the geospatial standards of the Natural Resources Values Information System (NRVIS).

Use the Geospatial Ontario Imagery Orders App to select and request uncompressed or compressed digital imagery tiles from Geospatial Ontario for transfer directly to you.

This collection was digitally converted from 148 rolls (64000 frames) of colour infrared aerial photography to a professional quality digital version that supports orthorectification, better feature interpretation and high-resolution inkjet printing. The photos were originally taken during the summers of 1994-2002 at approximately 1:10000 scale. The digital conversion occurred during 2006.

Contained within the Atlas of Canada's Various Map Series, 1965 to 2006, is is the first of a planned series of regional satellite image maps of all of Canada. It was one of the first satellite image maps to combine imagery and other map components such as boundaries, roads, railways and place names. The imagery is a composite of many images from the United States National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) satellites. The imagery was captured between August 11 to 20, 1990 to obtain cloud-free coverage. This was the only map in this planned series that was produced.

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 High Resolution Digital Elevation Model (HRDEM) product is derived from airborne LiDAR data (mainly in the south) and satellite images in the north. The complete coverage of the Canadian territory is gradually being established. It includes a Digital Terrain Model (DTM), a Digital Surface Model (DSM) and other derived data. For DTM datasets, derived data available are slope, aspect, shaded relief, color relief and color shaded relief maps and for DSM datasets, derived data available are shaded relief, color relief and color shaded relief maps. The productive forest line is used to separate the northern and the southern parts of the country. This line is approximate and may change based on requirements. In the southern part of the country (south of the productive forest line), DTM and DSM datasets are generated from airborne LiDAR data. They are offered at a 1 m or 2 m resolution and projected to the UTM NAD83 (CSRS) coordinate system and the corresponding zones. The datasets at a 1 m resolution cover an area of 10 km x 10 km while datasets at a 2 m resolution cover an area of 20 km by 20 km. In the northern part of the country (north of the productive forest line), due to the low density of vegetation and infrastructure, only DSM datasets are generally generated. Most of these datasets have optical digital images as their source data. They are generated at a 2 m resolution using the Polar Stereographic North coordinate system referenced to WGS84 horizontal datum or UTM NAD83 (CSRS) coordinate system. Each dataset covers an area of 50 km by 50 km. For some locations in the north, DSM and DTM datasets can also be generated from airborne LiDAR data. In this case, these products will be generated with the same specifications as those generated from airborne LiDAR in the southern part of the country. The HRDEM product is referenced to the Canadian Geodetic Vertical Datum of 2013 (CGVD2013), which is now the reference standard for heights across Canada. Source data for HRDEM datasets is acquired through multiple projects with different partners. Since data is being acquired by project, there is no integration or edgematching done between projects. The tiles are aligned within each project. The product High Resolution Digital Elevation Model (HRDEM) is part of the CanElevation Series created in support to the National Elevation Data Strategy implemented by NRCan. Collaboration is a key factor to the success of the National Elevation Data Strategy. Refer to the “Supporting Document” section to access the list of the different partners including links to their respective data.

Tree damage reported in Quetico Provincial Park by the Ministry of Natural Resources and Forestry. Satellite imagery review of a storm track revealed a tornado damage path through forested areas. The tornado developed in Ontario and tracked SE before crossing the international border at Ottertrack Lake into Minnesota. High-resolution aerial imagery was collected in July 2017 for a portion of the damage track.Damage assessed as EF2, with an estimated max. wind speed of 190 km/h, a track length over Canadian soil of 17.0 km (total track length was 19.7 km) and max. path width of 510 m (occurred within the portion of the track on Canadian soil). Tornado motion from the NW (approx. 315 degrees).

Aviation and Forest Fire Management (AFFM) Quickbird consists of high resolution imagery data covering build up areas throughout Ontario but mostly the West Fire Region. This data consists of orthorectified image derivatives from the Level Basic-1B bundled imagery provided to the OMNR by Digital Globe Inc. Pansharpened images (60-70cm true color composites) are required for mapping applications that require high resolution background imagery.

In the oil sands air monitoring component, nitrogen dioxide (NO2) and sulphur dioxide (SO2) levels are monitored by ground-based instruments, satellites and other measurements. Monitoring of air pollutants from satellites is becoming an alternative to surface and aircraft measurements, and allows for better understanding of the global distribution, sources and trends of pollutants. Figures showing NO2 and SO2 datasets are given in “Satellite Figures-EngFr.pdf”. Using satellite data collected over the oil sands region, high-resolution air pollutant maps show distinct concentrations of NO2 (Figure 1a) and SO2 (Figure 1b) over an area (roughly 30 km x 50 km, or 19 miles x 31 miles) of intensive oil sands surface mining. The map shows that NO2 concentrations are significant and are comparable to measurements made over large, individual sources such as coal-burning power plants. NO2 concentrations in the oil sand region are smaller than in large metropolitan areas in Canada and significantly smaller than elsewhere in North America (Figures 1c and 1d). The SO2 concentrations (Figure 1e) are also significant and are comparable to those from individual industrial emissions sources, including large base-smelting operations in Manitoba and Ontario. NO2 data are provided in the files described below; SO2 data may be added to the data catalogue in the future. The 2024 version (v4.0_OS) OMI NO2 data product builds on the previously published version of National Aeronautics and Space Administration (NASA) Ozone Monitoring Instrument (OMI) NO2 data, but includes more recent data, covering the period of 2004 to 2023 inclusive. Data are provided in netcdf format and cover the spatial domain of the entirety of the oil sands within a box defined by 53-58°N and 113-118°W. The data product is based on the NASA and OMI improved algorithms and Environment and Climate Change Canada (ECCC) post-processing algorithms to optimize the data for monitoring over Canada. This ECCC product has been shown to be more accurate as compared to the original NASA version over the oil sands region and thus it is the recommended version. OMI-derived maps of NO2 over the surface mining area for the 2004-2023 period, sample python code to load the data, references and other details are provided in “2024 OMI NO2 Supplemental Information EngFr.pdf” document. Included maps of NOx emissions between 2004-2023 help to understand the response to introduced ambient air quality standards and demonstrate that NO2 emissions increased from about 55 to 80 kt[NO2]/yr between 2005 –2011, and then remain roughly constant, which is broadly in line with reported emissions.
