  2. One-factor-at-a-time method - Wikipedia

    en.wikipedia.org/wiki/One-factor-at-a-time_method

    The one-factor-at-a-time method, [1] also known as one-variable-at-a-time, OFAT, OF@T, OFaaT, OVAT, OV@T, OVaaT, or monothetic analysis is a method of designing experiments involving the testing of factors, or causes, one at a time instead of multiple factors simultaneously.

  3. Friction of distance - Wikipedia

    The result was a strongly localized human geography, manifested in aspects as varied as language and economy. One of the most profound effects of the technological advances since 1800, including the railroad , the automobile , and the telephone , has been to drastically reduce the costs of moving people, goods, and information over long distances.

  4. Modifiable areal unit problem - Wikipedia

    en.wikipedia.org/wiki/Modifiable_areal_unit_problem

    The modifiable areal unit problem (MAUP) is a source of statistical bias that can significantly impact the results of statistical hypothesis tests. MAUP affects results when point-based measures of spatial phenomena are aggregated into spatial partitions or areal units (such as regions or districts ) as in, for example, population density or ...

  5. River rejuvenation - Wikipedia

    en.wikipedia.org/wiki/River_rejuvenation

    The process is often a result of a sudden fall in sea level or the rise of land. The disturbance enables a rise in the river's gravitational potential energy change per unit distance, increasing its riverbed erosion rate. The erosion occurs as a result of the river adjusting to its new base level. [1]

  6. Distance decay - Wikipedia

    en.wikipedia.org/wiki/Distance_decay

    Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. [1] The distance decay effect states that the interaction between two locales declines as the distance between them increases.

  7. Geographical feature - Wikipedia

    en.wikipedia.org/wiki/Geographical_feature

    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. Time is fundamental to the representation of a feature, although it does not have independent temporal descriptions. [ 20 ]

  8. Tobler's first law of geography - Wikipedia

    en.wikipedia.org/wiki/Tobler's_first_law_of...

    The First Law of Geography, according to Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." [1] This first law is the foundation of the fundamental concepts of spatial dependence and spatial autocorrelation and is utilized specifically for the inverse distance weighting method for ...

  9. Cartographic generalization - Wikipedia

    en.wikipedia.org/wiki/Cartographic_generalization

    During the first half of the 20th century, cartographers began to think seriously about how the features they drew depended on scale. Eduard Imhof, one of the most accomplished academic and professional cartographers at the time, published a study of city plans on maps at a variety of scales in 1937, itemizing several forms of generalization that occurred, including those later termed ...
