    Absolute location, a location as described by its latitude and longitude on the Earth. For example, the coordinates of Albany, New York are 42.6525° N, 73.7572° W. Relative location, a location as described by where it is compared to something else. For example, Albany, New York is roughly 140 miles north of New York City.

    An icon representing the concept of location. In geography, location or place are used to denote a region (point, line, or area) on Earth's surface.The term location generally implies a higher degree of certainty than place, the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry.

  4. Address geocoding - Wikipedia

    en.wikipedia.org/wiki/Address_geocoding

    An example of a relative geocode is "Across the street from the Empire State Building." The location being sought cannot be determined without identifying the Empire State Building. Geocoding platforms often do not support such relative locations, but advances are being made in this direction. Absolute input data

    en.wikipedia.org/wiki/Spatial_reference_system

    A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates.It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.

    The Earth-centered, Earth-fixed coordinate system (acronym ECEF), also known as the geocentric coordinate system, is a cartesian spatial reference system that represents locations in the vicinity of the Earth (including its surface, interior, atmosphere, and surrounding outer space) as X, Y, and Z measurements from its center of mass.

  7. Geospatial PDF - Wikipedia

    en.wikipedia.org/wiki/Geospatial_PDF

    After importing geospatial data into PDF, one can use the data in a variety of ways: [1] Find and mark location coordinates. Measure distance, perimeter, and area. Change the coordinate system and measurement units. Copy location coordinates to the clipboard, and then use them to show locations in several web mapping services.

  8. Linguistic frame of reference - Wikipedia

    en.wikipedia.org/wiki/Linguistic_frame_of_reference

    A frame of reference is a coordinate system used to identify the physical location of an object. In languages, different frames of reference can be used. They are: the relative frame of reference, the intrinsic frame of reference, and the absolute frame of reference. Each frame of reference in a language can be associated with distinct ...

    en.wikipedia.org/wiki/Spreadsheet

    A spreadsheet consists of a table of cells arranged into rows and columns and referred to by the X and Y locations. X locations, the columns, are normally represented by letters, "A," "B," "C," etc., while rows are normally represented by numbers, 1, 2, 3, etc. A single cell can be referred to by addressing its row and column, "C10".
