A proposal has been developed [12] to extend Geo to cover other bodies, such as Mars and the Moon. An example is the Flickr photo-sharing Web site, which provides geographic data for any geotagged photo in all of the above-mentioned formats.
There are also many different types of geodata, including vector files, raster files, geographic databases, web files, and multi-temporal data. Spatial data or spatial information is broader class of data whose geometry is relevant but it is not necessarily georeferenced , such as in computer-aided design (CAD), see geometric modeling .
In theory, every part of a picture can be tied to a geographic location, but in the most typical application, only the position of the photographer is associated with the entire digital image. This has implications for search and retrieval. For example, photos of a mountain summit can be taken from different positions miles apart.
Graphical view of the affine transformation. The registration of an image to a geographic space is essentially the transformation from an input coordinate system (the inherent coordinates of pixels in the images based on row and column number) to an output coordinate system, a spatial reference system of the user's choice, such as the geographic coordinate system or a particular Universal ...
Geo-Wiki is a platform for engaging citizens and experts in both environmental and socioeconomic monitoring, established in 2009 at the International Institute for Applied Systems Analysis . It aids in both, the validation of existing geographical information and the collection of new geographical information through crowdsourcing [ 1 ] [ 2 ...
National Geographic Image Collection, a division of the National Geographic Partners, a joint venture between the National Geographic Society and The Walt Disney Company, headquartered in Washington, D.C., United States, was a stock photography agency that managed and licensed one of the world's most comprehensive and unique collections of photographs and original artwork.
Geography (Greek Geo (γη) or Gaea (γαία), meaning "Earth", and graphein (γράφειν) meaning "to describe" or "to write") is the study of the earth and its features, inhabitants, and phenomena. A literal translation would be "to describe or write about the Earth". The first person to use the word "geography" was Eratosthenes (275
Attributes, characteristics of a feature other than location, often expressed as text or numbers; for example, the population of a city. [19] In geography, the levels of measurement developed by Stanley Smith Stevens (and further extended by others) is a common system for understanding and using attribute data.
