The phenakistiscope (also known by the spellings phénakisticope or phenakistoscope) was the first widespread animation device that created a fluid illusion of motion. Dubbed Fantascope and Stroboscopische Scheiben ('stroboscopic discs') by its inventors, it has been known under many other names until the French product name Phénakisticope ...
EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement, originated by a member of the European Petroleum Survey Group (EPSG) in 1985.
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Geographic data and information are the subject of a number of overlapping fields of study, mainly: Geocomputation; Geographic information science. Geographic information science and technology; Geoinformatics; Geomatics; Geovisualization "Geospatial technology" may refer to any of "geomatics", "geomatics", or "geographic information technology."
In both mathematics and geodesy, a coordinate system is a "coordinate system" per ISO terminology, whereas the International Earth Rotation and Reference Systems Service (IERS) uses the term "reference system" for the same. When coordinates are realized by choosing datum points and fixing a geodetic datum, ISO speaks of a "coordinate reference ...
A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame, or terrestrial reference frame) is a global datum reference or reference frame for unambiguously representing the position of locations on Earth by means of either geodetic coordinates (and related vertical coordinates) or geocentric coordinates.

The geographical location of the map sheets in this system can be directly localized. Unlike the previous system, each adjacent lower (southern) row bears lower numbers, and the final digit for each of the sheets in a particular row is always the same. At least in Central Europe, the numbers used in this system are made up of four digits.
Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. [2]
