Channel patterns are found in rivers, streams, and other bodies of water that transport water from one place to another.Systems of branching river channels dissect most of the sub-aerial landscape, each in a valley proportioned to its size.
Ashlar (/ ˈ æ ʃ l ər /) is a cut and dressed stone, worked using a chisel to achieve a specific form, typically rectangular in shape. The term can also refer to a structure built from such stones. [1] Ashlar is the finest stone masonry unit, and is generally rectangular . It was described by Vitruvius as opus isodomum or trapezoidal.
[1] bore 1. A steep-fronted wave formed by the convergence of two tidal bulges or by the constriction of an incoming tide as it travels up a river, firth, or narrow bay, temporarily reversing the direction of the current. [4] 2. A deep, man-made hole or shaft drilled into the ground, e.g. in mining, or for digging a well or tunnel.
Point pattern analysis (PPA) [1] is the study of point patterns, the spatial arrangements of points in space (usually 2-dimensional space). The simplest formulation is a set X = { x ∈ D } where D , which can be called the 'study region,' is a subset of R n , a n -dimensional Euclidean space .
Pattern detection via the identification of such geographical clusters is a very simple and generic form of geographical analysis that has many applications in many different contexts. The emphasis is on localized clustering or patterning because this may well contain the most useful information. [citation needed]
Two adjacent vermiculated blocks showing rather different interpretations of the pattern. The most common variation of rustication is the smooth-faced, where the external face of the block is smooth, as in ashlar, and differs from that only by the cutting in at the joints; this became increasingly popular, and is now the most commonly seen type.
A thematic map is a type of map that portrays the geographic pattern of a particular subject matter (theme) in a geographic area. This usually involves the use of map symbols to visualize selected properties of geographic features that are not naturally visible, such as temperature, language, or population. [ 1 ]
John Edward Marr in his The Scientific Study of Scenery [23] considered his book as, 'an Introductory Treatise on Geomorphology, a subject which has sprung from the union of Geology and Geography'. An early popular geomorphic model was the geographical cycle or cycle of erosion model of broad-scale landscape evolution developed by William ...
