A Digital Orthophoto Quadrangle (DOQ) is a computer-generated image of an aerial photograph in which the image displacement caused by terrain relief and camera tilt has been removed. The DOQ combines the image characteristics of the original photograph with the georeferenced qualities of a map. DOQs are black and white (B/W), natural color, or color-infrared (CIR) images with 1-meter ground resolution. The USGS produces three types of DOQs: 3.75-minute (quarter-quad) DOQs cover an area measuring 3.75-minutes longitude by 3.75-minutes latitude. Most of the U.S. is currently available, and the remaining locations should be complete by 2004. Quarter-quad DOQs are available in both Native and GeoTIFF formats. Native format consists of an ASCII keyword header followed by a series of 8-bit binary image lines for B/W and 24-bit band-interleaved-by-pixel (BIP) for color. DOQs in native format are cast to the Universal Transverse Mercator (UTM) projection and referenced to either the North American Datum (NAD) of 1927 (NAD27) or the NAD of 1983 (NAD83). GeoTIFF format consists of a georeferenced Tagged Image File Format (TIFF), with all geographic referencing information embedded within the .tif file. DOQs in GeoTIFF format are cast to the UTM projection and referenced to NAD83. The average file size of a B/W quarter quad is 40-45 megabytes, and a color file is generally 140-150 megabytes. Quarter-quad DOQs are distributed via File Transfer Protocol (FTP) as uncompressed files. 7.5-minute (full-quad) DOQs cover an area measuring 7.5-minutes longitude by 7.5-minutes latitude. Full-quad DOQs are mostly available for Oregon, Washington, and Alaska. Limited coverage may also be available for other states. Full-quad DOQs are available in both Native and GeoTIFF formats. Native is formatted with an ASCII keyword header followed by a series of 8-bit binary image lines for B/W. DOQs in native format are cast to the UTM projection and referenced to either NAD27 or NAD83. GeoTIFF is a georeferenced Tagged Image File Format with referencing information embedded within the .tif file. DOQs in GeoTIFF format are cast to the UTM projection and referenced to NAD83. The average file size of a B/W full quad is 140-150 megabytes. Full-quad DOQs are distributed via FTP as uncompressed files. Seamless DOQs are available for free download from the Seamless site. DOQs on this site are the most current version and are available for the conterminous U.S. [Summary provided by the USGS.]

Combined product: Digital Topographic Map 1:5000 (Normal Edition - TK5N) with Digital Orthophoto 0,2 m Rhineland-Palatinate (Specification: DOP20 RGB) (TK5L20) Topographic maps are landscape-descriptive maps in which the surface of the earth is represented. The DTK5 contains the essential objects of the earth's surface such as settlements, transport networks, vegetation, waters and terrain, property boundaries, boundaries of political and administrative units with names and other descriptive information. With its combination of topography and property boundaries, it forms the link between the property map and the topographic maps. Digital orthophotos (DOP) are distortion-free and true-to-scale photographic images of the earth's surface. They are derived from oriented digital aerial images and a digital elevation model. TrueDOP uses an image-based digital surface model (bDOM) as its elevation model.

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.

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.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Large scale final map products were created within ArcMap and designed to show both the orthophoto coverage and the vegetation maps. For the vegetation maps, colors were assigned and the polygons labeled with the dominant vegetation and modifier and, where present, the second vegetation and modifier. For the orthophoto maps, the photos were simply plotted at the same scale and area coverage as the vegetation maps. Additional planimetric map data included roads, trails, hydrology, boundaries and a UTM coordinate grid. Legends are designed to provide full definitions of the vegetation and buffer classes and modifiers, as well as information about the park, map projection, data sources and authorship (Figure 19). All maps are projected to the Universal Transverse Mercator Coordinate System, North American Datum of 1984, in the local zone for the specific park.

(Link to Metadata) RF 5000 scale orthophoto edge lines (4000 x 4000 meter grid cells) were generated automatically from the known corner locations. These corners apply to all analog (paper) orthophotos produced between 1974 and 1994 (NAD27). This coverage should be used when digitizing data from NAD27 orthophotos. Orthophotos developed after 1994 utilize a different map grid system (offset to the west by about 130 meters), and are in NAD83. The ORTHO_83 data layer should be used when digitizing from NAD83 orthophotos. The ORTHO data layer should NOT be used for digitizing.

(Link to Metadata) RF 5000 NAD83 orthophoto edge lines (4000 x 4000 meter grid cells) were generated automatically from the known corner locations (generated by Gary Smith). Corner tics were added by VCGI. Nodes-intersections at the corner of each ortho tile (polygon) was converted into a point data layer. The Arc/Info NEAR command was then used to transfer tic IDs from the ORTHO data layer to this data layer. These points were then converted to tics and appended to this coverage. These corners apply to only to NAD83 orthophotos (digital and hardcopy). The corners of digital orthophotos DO NOT precisely match the older corners/boundaries in the BoundaryTile_ORTHO27 data layer. Corners and boundaries have been shifted on the X-axis (easting) by approximately 135 meters to the west, and 8 meters in the Y-axis (northing) . Please refer to BoundaryTile_ORTHO27 data layer documentation for additional information. The corner tic IDs and IDTIC attributes contain the same numbering scheme used in the BoundaryTile_ORTHO27 coverage (even though corners and boundaries are not the same). These tics can be used to digitize NAD83 orthophotos . The BoundaryTile_ORTHO27 data layer should be used when digitizing from NAD27 orthophotos. The ORTHO data layer should NOT be used for digitizing.

In Latvia, orthophoto maps are prepared in the Latvian coordinate system LKS-92 TM according to the TKS-93 map sheet division (scale 1:10000 map sheet corresponds to 5 x 5 kilometers in nature). Orthophoto maps are prepared for the whole territory of Latvia at the scale of 1:10000, but for separate territories - for cities and densely populated areas - at the scale of 1:2000 or 1:1000. The CIR dataset has three bands: Near-Infrared, Red, and Green. For more information, please see the Latvia orthophotos documentation

WMS service created on the basis of official DOF5 maps DGU. Digital orthophoto map (DOF5) is an official state map and is produced on a scale of 1:5 000 for the entire area Of the Republic of Croatia. Orthophoto card is a card sheet composed of one or more orthophotos uniform scale with rectangular coordinate grid applied, appropriate cartographic signs supplemented outside the indicative data. DOF5 up in the area The Republic of Croatia has been systematically produced since 2000. The entire territory of the Republic of Croatia it’s covered with 10945 sheets of DOF5. The area of one sheet covers an area of 600 ha. The basic product on which the production of DOF5 is based are aerophotogrammetric images recorded according to the corresponding Product Technical Specifications. DOF5 is used for administrative purposes, in particular for urban and rural planning. Until 2009 DOF5 is made in Zone 5 and 6 of Gauss-Krueger’s cartographic projections on Bessel’s ellipsoid 1841, and since 2009 in the new cartographic projection HTRS96/TM on the ellipsoid GRS80.

The City of Brampton 2023 Spring Orthophoto was captured at 10 cm resolution and orthorectified.An orthophoto, orthophotograph or orthoimage is an aerial photograph geometrically corrected ("orthorectified") such that the scale is uniform: the photo has the same lack of distortion as a map. Unlike an uncorrected aerial photograph, an orthophotograph can be used to measure true distances, because it is an accurate representation of the Earth's surface, having been adjusted for topographic relief, lens distortion, and camera tilt. - https://en.wikipedia.org/wiki/Orthophoto
