This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Mountain range – Geographic area containing several geologically related mountains; Nunatak – Landform within an ice field or glacier; Proglacial lake – Lake formed by the action of ice; Pyramidal peak, also known as Glacial horn – Angular, sharply pointed mountainous peak; Outwash fan – Type of sediment deposition by a melting glacier
Objects of studies in geography are inter alia locations, activities and flows of individuals, but also networks evolving in time and space. [4] Most of the important problems such as the location of nodes of a network, the evolution of transportation networks and their interaction with population and activity density are addressed in these ...
A common type of lattice graph (known under different names, such as grid graph or square grid graph) is the graph whose vertices correspond to the points in the plane with integer coordinates, x-coordinates being in the range 1, ..., n, y-coordinates being in the range 1, ..., m, and two vertices being connected by an edge whenever the corresponding points are at distance 1.
The German term Landschaftsökologie – thus landscape ecology – was coined by German geographer Carl Troll in 1939. [10] He developed this terminology and many early concepts of landscape ecology as part of his early work, which consisted of applying aerial photograph interpretation to studies of interactions between environment and vegetation.
Note the potential savings in terms of space when these trees are used for storing images; images often have many regions of considerable size that have the same colour value throughout. Rather than store a big 2-D array of every pixel in the image, a quadtree can capture the same information potentially many divisive levels higher than the ...
In geometry and group theory, a lattice in the real coordinate space is an infinite set of points in this space with the properties that coordinate-wise addition or subtraction of two points in the lattice produces another lattice point, that the lattice points are all separated by some minimum distance, and that every point in the space is within some maximum distance of a lattice point.
The term graticule is almost always used to specifically refer to the parallels and meridians of latitude and longitude respectively in the geographic coordinate system. In modern usage, graticules are contrasted with grids , which display the eastings and northings of a projected coordinate reference system , such as Universal Transverse ...
