In geography, scale is the level at which a geographical phenomenon occurs or is described. This concept is derived from the map scale in cartography . Geographers describe geographical phenomena and differences using different scales.
In geography, different geographic (scale) levels are distinguished: The local scale level relates to a small area, usually a city or municipality; The regional scale level relates to a larger area, usually a region, state or province; The national scale level relates to a country; The continental scale level refers to a continent;
Often called mean sea level (MSL), it is a type of standardized geodetic vertical datum that is used in numerous applications, including surveying, cartography, and navigation. Mean sea level is commonly defined as the midpoint between the mean low and mean high tides at a particular location. [6] sea stack See stack. seabed. Also sea floor or ...
The other form is statistical downscaling, where a statistical relationship is established from observations between large scale variables, like atmospheric surface pressure, and a local variable, like the wind speed at a particular site. The relationship is then subsequently used on the GCM data to obtain the local variables from the GCM output.
In modern mapping, a topographic map or topographic sheet is a type of map characterized by large-scale detail and quantitative representation of relief features, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.
Within the branch of materials science known as material failure theory, the Goodman relation (also called a Goodman diagram, a Goodman-Haigh diagram, a Haigh diagram or a Haigh-Soderberg diagram) is an equation used to quantify the interaction of mean and alternating stresses on the fatigue life of a material.

Spatial scale is a specific application of the term scale for describing or categorizing (e.g. into orders of magnitude) the size of a space (hence spatial), or the extent of it at which a phenomenon or process occurs. [1] [2] For instance, in physics an object or phenomenon can be called microscopic if too small to be visible.
This can vary according to the slope and amplitude of the terrestrial relief, but is usually three to five times the horizontal scale. A series of parallel profiles, taken at regular intervals on a map, can be combined to provide a more complete three-dimensional view of the area that appears on the topographic map.
