The U.S. Geological Survey (USGS) Aerial Photography data set includes over 2.5 million film transparencies. Beginning in 1937, photographs were acquired for mapping purposes at different altitudes using various focal lengths and film types. The resultant black-and-white photographs contain less than 5 percent cloud cover and were acquired under rigid quality control and project specifications (e.g., stereo coverage, continuous area coverage of map or administrative units). Prior to the initiation of the National High Altitude Photography (NHAP) program in 1980, the USGS photography collection was one of the major sources of aerial photographs used for mapping the United States. Since 1980, the USGS has acquired photographs over project areas that require photographs at a larger scale than the photographs in the NHAP and National Aerial Photography Program collections.

The National Aeronautics and Space Administration (NASA) Aerial Photography data set is a film archive of photographs from the Lyndon B. Johnson Space Center (JSC) in Houston, Texas, and the NASA Ames Research Center in Moffett Field, California. In 1965, the JSC initiated the Earth Resources Aircraft Program and began flying photographic missions for Federal Government agencies and other entities involved in remote sensing experiments. Beginning in 1966, NASA conducted an Earth Observations Program, including Earth surveys using aircraft platforms. Photographs from a variety of NASA programs provide project-specific coverage over the United States, Grand Bahama, Jamaica, and Central America at base scales ranging from 1:16,000 scale to 1:450,000 scale. Film types, scales, acquisition schedules, flight altitudes, and end products differ, according to project requirements.

The aerial photo flight index shows the aerial photo and flight information, including photo number, shooting position, photo coverage, date of flight, flying height etc., of the aerial photographs taken by Survey and Mapping Office (SMO). There are three file formats, XLS / XLSX, KML and KMZ for download. The file in KML and KMZ file format is geo-referenced to World Geodetic System (WGS84), containing both aerial photo and flight information, while the file in XLS / XLSX file format only contains the aerial photo information.

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.

'USGS and Non USGS Agencies Aerial Photo Reference Mosaics inventory contains indexes to aerial photographs. The inventory contains imagery from various government agencies that are now archived at the USGS Earth Resources Observation and Science (EROS) Center. The film types, scales, and acquisition schedules differed according to project requirements. Low-, middle-, and high-altitude photographs were collected. '

'The National High Altitude Photography (NHAP) program, which was operated from 1980-1989, was coordinated by the U.S. Geological Survey as an interagency project to eliminate duplicate photography in various Government programs. The aim of the program was to cover the 48 conterminous states over a 5-year span. In the NHAP program, black-and-white and color-infrared aerial photographs were obtained on 9-inch film from an altitude of 40,000 feet above mean terrain elevation and are centered over USGS 7.5-minute quadrangles. The color-infrared photographs are at a scale of 1:58,000 (1 inch equals about .9 miles), and the black-and-white photographs are at a scale of 1:80,000 (1 inch equals about 1.26 miles). All NHAP flights were flown in a North to South direction. These photographs are offered as digital images. '

This dataset features a collection of historical orthorectified aerial photographed images of the Brisbane City Council local government area captured by piloted aircraft during 1946.Prior to satellite imagery, extensive use was made of aerial photography to capture land information. The 1946 imagery service uses the Geocentric Datum of Australia 1994 (GDA94) datum and is projected in Zone 56 of the Map Grid of Australia (MGA56).This dataset is a tile layer, to view the images or to access the data, use the ArcGIS Hub, HTML and API links in the Data and resources section below.

Digital imagery has been acquired for Tasmanian from 2010 to present day. The Digital Aerial Imagery Season Orthomosaics are compilations of aerial imagery captured for each flying season, during the summer season from October through to the following March. The mosaics are compiled from high resolution imagery, usually captured at 10cm and 25cm resolution.

Aerial Photography and Imagery, Uncorrected dataset current as of 1961. Hard copy aerial photographs taken in 1961..

The Analogue Aerial Imagery Season Orthomosaics are compilations of aerial imagery captured for each flying season, during the summer season from October through to the following March. For older imagery prior to 2000, mosaics have been compiled into decades. The mosaics are compiled from film based analogue imagery, captured at various scales.

This data set contains imagery from the National Agriculture Imagery Program (NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S.. A primary goal of the NAIP program is to enable availability of of ortho imagery within one year of acquisition. NAIP provides four main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 5 meters of reference digital ortho quarter quads (DOQQ's) from the National Digital Ortho Program (NDOP); 2 meter GSD ortho imagery rectified to within +/- 10 meters of reference DOQQs; 1 meter GSD ortho imagery rectified to within +/- 6 meters to true ground; and, 2 meter GSD ortho imagery rectified to within +/- 10 meters to true ground. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are formatted to the UTM coordinate system using NAD83. NAIP imagery may contain as much as 10% cloud cover per tile.NAIP imagery is available for distribution within 60 days of the end of a flying season and is intended to provide current information of agricultural conditions in support of USDA farm programs. For USDA Farm Service Agency, the 1 meter GSD product provides an ortho image base for Common Land Unit boundaries and other data sets. The 1 meter NAIP imagery is generally acquired in projects covering full states in cooperation with state government and other federal agencies who use the imagery for a variety of purposes including land use planning and natural resource assessment. With an annual cycle, NAIP is also used for disaster response often providing the most current pre-event imagery. While suitable for a variety of uses the 2 meter GSD NAIP imagery is primarily intended to assess crop condition and compliance to USDA farm program conditions. The 2 meter imagery is generally acquired only for agricultural areas within state projects.
