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 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.

Aerial Imagery (.sid file) of the City of Waterloo, Ontario, Canada, captured in spring 2020. Note this is a large file and may take some time to download.

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.

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.

This colour aerial photography was flown using a Zeiss Jena LMK15 aerial camera equipped with a 6" (152mm) focal length lens mounted in a Piper Aztec F aircraft. It was captured on September 15, 28, and 29, 1995. The altitude of the aircraft, 15,000 feet above mean ground, provided photography at a nominal scale of 1:30000. Originally captured on film, the imagery was converted digitally and orthorectified. The final product has the same accuracy as a 1:20000 map.

Time of Capture: September 1995 Coverage: 6,289 sq km Canopy Coverage: Leaf-Off

The Ontario Raw Point Cloud (Imagery-Derived) is elevation point cloud data created from aerial photography from the Geospatial Ontario (GEO) imagery program. It was created using a pixel-autocorrelation process based on aerial photography collected by the imagery contractor for the GEO imagery program. The dataset consists of overlapping tiles in LAZ format and is 6.29 terabytes in size. Tiles 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. This data is for geospatial tech specialists, and is used by government, municipalities, conservation authorities and the private sector for land use planning and environmental analysis. Related data 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. For a representation of bare earth, see Ontario Digital Elevation Model (Imagery-Derived). For a model representing all surface features, see the Ontario Digital Surface Model (Imagery-Derived).

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.
