  3. Geography - Wikipedia

    en.wikipedia.org/wiki/Geography

    Geography is subject to the laws of physics, and in studying things that occur in space, time must be considered. Time in geography is more than just the historical record of events that occurred at various discrete coordinates; but also includes modeling the dynamic movement of people, organisms, and things through space.

  4. Coastline paradox - Wikipedia

    en.wikipedia.org/wiki/Coastline_paradox

    The coastline paradox is the counterintuitive observation that the coastline of a landmass does not have a well-defined length. This results from the fractal curve-like properties of coastlines; i.e., the fact that a coastline typically has a fractal dimension.

  5. Spatial reference system - Wikipedia

    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 Geography Markup Language (GML) is an XML encoding in compliance with ISO 19118 for the transport and storage of geographic information modelled according to the conceptual modelling framework used in the ISO 19100-series and including both the spatial and nonspatial properties of geographic features.

  8. Projected coordinate system - Wikipedia

    en.wikipedia.org/wiki/Projected_coordinate_system

    Since, in the UK at least, a 6-figure grid reference identifies a square of 100-metre sides, an 8-figure reference would identify a 10-metre square, and a 10-digit reference a 1-metre square. In order to give a standard 6-figure grid reference from a 10-figure GPS readout, the 4th, 5th, 9th and 10th digits must be omitted, so it is important ...
