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 manuscript is submitted for publication at the ISPRS International Journal of Geo-Information.

As an example for the representation of glaciers using orthophoto maps the new map "Langtaler Ferner 1971" is presented. The orthophoto map shows the glacier "Langtaler Ferner" in the Oetztal Alps (Austria) on August 18, 1971. Apart from a description of the map production and a discussion of the advantages and disadvantages of such ortho- photo maps for the representation of glacierized areas, the stage of the "Langtaler Ferner" at the time of the ftight is described. A comparison with some data of previollsly published maps is also included.

This dataset details features of Marine Plain in the Vestfold Hills, Antarctica. The dataset includes coastline, 5 metre interval contours and lake shores.

Combined product: Digital Topographic Map 1:5000 (Normal Edition - TK5N) with Digital Orthophoto 0,4 m Rhineland-Palatinate (Specification: DOP40 RGB) (TK5L40) 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.

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.]

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.

In Spring 2019, with funding from several State partners, MassGIS contracted with the U.S. Geological Survey for statewide, 15 cm resolution, 16-bit, 4-band (RGB-IR) digital orthophotos. The data were delivered in early 2020 as 10,218 individual 1,500 m x 1,500 m tiles in a GeoTIFF format. To allow for easier distribution of this free imagery, MassGIS compressed the GeoTIFFS into the JPEG 2000 format, which retains the IR band. The tile naming convention is based on the U.S. National Grid (USNG), taking the coordinates of the southwest corner of the tile.Project specifications are based on the American Society of Photogrammetry and Remote Sensing (ASPRS) standards. The data were developed based on a horizontal projection/datum of NAD 1983 2011 UTM zones 18N and 19N meters and a vertical projection/datum of NAVD 88 (GEOID 12B) meters.This digital orthoimagery was created to provide easily accessible geospatial data which are readily available to enhance the capability of federal, state, and local emergency responders, as well as to plan for homeland security efforts. These data also support The National Map.These images can serve a variety of purposes, from general planning to field reference for spatial analysis, to a tool for data development and revision of vector maps. The imagery can also serve as a reference layer or basemap for myriad applications inside geographic information system (GIS) software and web-based maps.This image service was created using JPEG 2000 versions of the imagery that MassGIS converted from GeoTiffs and distributes online.For more information see the imagery's MassGIS metadata page.
