High resolution orthorectified images combine the image characteristics of an aerial photograph with the geometric qualities of a map. An orthoimage is a uniform-scale image where corrections have been made for feature displacement such as building tilt and for scale variations caused by terrain relief, sensor geometry, and camera tilt. A mathematical equation based on ground control points, sensor calibration information, and a digital elevation model is applied to each pixel to rectify the image to obtain the geometric qualities of a map. A digital orthoimage may be created from several photographs mosaicked to form the final image. The source imagery may be black-and-white, natural color, or color infrared with a pixel resolution of 1-meter or finer. With orthoimagery, the resolution refers to the distance on the ground represented by each pixel.

This dataset provides links to aerial imagery (orthophoto) taken in 2022 as individual tiled areas over the City of Vancouver.An orthophoto is an aerial photograph that has been processed (via a scanning and rectification process) in such a way as to eliminate image displacement due to camera tilt and terrain relief, so that it represents every object as if viewed directly from above, as in a map which is usually in an orthographic projection. An orthophoto combines the visual properties of a photograph with the geometric qualities of a map and offers a realistic visualization of the landscape.The City's orthophoto coverage includes the City, UBC, and the University Endowment Lands and parts of Richmond and the Vancouver International Airport (YVR) as well. The area is defined by the City's facet grid (see Facet Grid Boundaries).Since the 2015 orthophotos, resolution for our imagery is 7.5 cm. Orthophotos are in coordinate system UTM NAD83, Zone 10 (EPSG:26910). Note​Atmospheric correction was not applied to this dataset. Data currency​The 2022 orthophotos were captured between June 6, 2022 and July 1, 2022. This imagery is current as of these dates.​ Data accuracy​Imagery is accurate as of the dates it was taken although colours may or may not be exactly as occurred on that day as colours change from moment to moment due to sun and cloud cover.

Spatial index to photo centers for multi-county 2012 Aerial Mapping Project, a 53 member consortium that collected aerial imagery for orthophoto production and other products. The layer provides photo flight information about the collected imagery. It is a reference for the raw image scans, it is not a index for tiled ortho imagery. The index shows the photo centers for all three resolution areas: 0.25 foot, 0.50 foot and 1.00 foot imagery.

description: This dataset is a single orthophoto from a collection of GeoTIFF format, natural-color orthophotos covering Collier County, Florida. The dataset covers an area of approximately 14.3 square miles. An orthophoto is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematicallyremoved. Orthophotography combines the image characteristics of a photograph with the geometric qualities of a map. Each orthophoto provides imagery for a 5000- by 5000-foot block on the ground at 2.0 foot pixel resolution. The projected coordinate system is State Plane, Florida East (FIPS 901), NAD83, Survey Feet. There is no image overlap in adjacent files. The imagery was captured using the Zeiss/Intergraph Digital Mapping Camera (DMC). The USGS National Elevation Data (NED) was used as a DEM surface for the orthorectification process. The orthophotos are available in GeoTIFF and MrSID compressed forms.; abstract: This dataset is a single orthophoto from a collection of GeoTIFF format, natural-color orthophotos covering Collier County, Florida.

BY USING THIS WEBSITE OR THE CONTENT THEREIN, YOU AGREE TO THE TERMS OF USE. This raster dataset consists of 8-bit, 4-band (R, G, B, NIR) color orthoimagery. A digital orthoimage is a raster image processed from vertical aerial images in which displacement in the image due to sensor orientation and terrain relief have been removed. Orthoimagery combines the image characteristics of an image with the geometric qualities of a map. Unlike planimetric maps which depict natural and manmade features by means of lines, point symbols, texts and polygons, orthoimagery illustrates the actual images of features and are thus more easily interpreted than regular maps. The normal orientation of data in an orthoimage is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. Each image tile is stored in industry standard TIFF (tagged interchange file format) with an associated TIFF world file. Aerial imagery was acquired on May 6, 2014, May 19, 2014 from flying heights of approximately 14500 feet above ground level (AGL). Each orthoimage tile is 5000 feet X 5000 feet in dimension, edge-tied with the adjacent tiles (no gap and no overlap).

Medium resolution true color ortho images for the Commonwealth of Massachusetts, distributed by MassGIS. The photography for the entire commonwealth was captured in April 2005 when deciduous trees were mostly bare and the ground was generally free of snow. Original imagery pixel resolution is 1/2-meter.Original image type is 4-band (RGBN) natural color (Red, Green, Blue) and Near infrared in 8 bits (values ranging 0-255) per band format. This map service contains only the RGB bands and uses the "contrast stretched" JPEG 2000 versions MassGIS Produced from the original GeoTiff files. Image horizontal accuracy is +/-3 meters at the 95% confidence level at the nominal scale of 1:5,000. This digital orthoimagery can serve a variety of purposes, from general planning, to field reference for spatial analysis, to a tool for development and revision of vector maps. It can also serve as a reference layer or basemap for myriad applications inside geographic information system (GIS) software. The project was funded by the Executive Office of Environmental Affairs, the Department of Environmental Protection, the Massachusetts Highway Department, and the Department of Public Health.For full metadata visit https://www.mass.gov/info-details/massgis-data-2005-aerial-imagery.

The Digital Globe 2011-2012 aerial-photo reference map layer contains visible color, 30-centimeter pixel resolution ortho imagery from Digital Globe captured in spring 2011 and spring 2012. Imagery was captured statewide in spring 2011 in nine delivery areas. In Spring 2012, Berkshire County (the "Pittsfield" delivery area) and the town of Barnstable were re-flown. Image acquisition consisted of "high value" and "standard" data, with the high value areas complying with more stringent standards. MassGIS created the ortho imagery base map such that the High Value imagery draws atop any Standard imagery where the areas overlap. The imagery was part of Digital Globe's Advanced Ortho Aerial Program “Precision Aerial” high-resolution orthomosaics.Please see the metadata for more details.

This dataset provides orthorectified aerial imagery (“orthophotos”) for the City of Courtenay. These tiles are used as a base layer for mapping, land use planning, and visual analysis. 5cm resolution. Taken March 2020.

Map of orthophotos of 1963 (Imagery Orthophoto Map1993) of free areas, from the collection of background maps of the Department of Land Registry and Surveying. The data shall be made available through a WMS service.

This data results from the NRSC's ongoing 1:25000 UK Aerial Photography Programme; a project designed to maintain an up to date aerial coverage of the United Kingdom, covering the complete area at least every 5 years.

The Orthoview product has been generated from vertical aerial photographs. The photographs have been orthorectified (to correct for distortion towards their edges) then mosaiced to provide a seamless dataset for the UK at a 0.5 metre resolution. This allows imagery for any area of interest to be generated without issues associated with scenes falling across multiple photographs.

In addition to its prime application in photogrammetric mapping (from updating and contouring existing maps to preparing large scale engineering plans), the data is used for environmental studies, general planning, land use and land capability, soils, pollution, forestry, mining and quarrying, housing and leisure development, agriculture, geology, water, transport and civil engineering, boundary disputes, public enquiries, etc.

The data is stored in digital form and can be supplied on either Exabyte, CD-ROM or CCT. Various hard copy forms can also be generated, including posters and photographic positives/negatives. Price lists and further information are available from the National Remote Sensing Centre (NRSC).

Note: All photography is flown to RICS Specification for Aerial Photography Issue III, see references.
