7127156420Central Place Theorydeveloped in the 1930s by the German geographer Walter Christaller, saw the economic world as an abstract spatial model, in which city location and the level of urban economic exchange could be analyzed using central places within hexagonal market areas, which overlapped each other at different scales37

7127156433Expansion diffusionthe pattern originates in a central place and then expands outward in all directions to other locations50
7127156434hierarchical diffusionthe pattern originates in a first order location then moves down to second-order locations and from each of these to subordinate locations at increasingly local scales51
7127156435relocation diffusionthe pattern begins at a point of origin and then crosses a significant physical barrier, such as an ocean, mountain range, or desert, then relocates on the other side, often the journey can influence and modify the items being diffused52
7127156436contagiousthe pattern begins at a point of origin and then moves outward to nearby locations, especially those on adjoining transportation lines, this could be used to describe a disease but can also describe the movement of other things, such as news in rural regions53
7127156437stimulus diffusionhere a general and underlying principle diffuses and then stimulates the creation of new products or ideas54
7127156438topographic mapshows the contour lines of elevation, as well as the urban and vegetation surface with road, building, river, and other natural landscape features. These maps are highly accurate in terms of location and topography. They are used for engineering surveys and land navigation, especially in wilderness regions55

7127156445equal-area projectionsattempt to maintain the relative spatial science and the areas on the map, however these can distort the actual shape of polygons, such as the Lambert projections bending and squishing the northern Canadian islands to keep them at the same map scale as southern Canada on a flat sheet of paper62
7127156446conformal projectionsattempt to maintain the shape of polygons on the map, the downside is that conformal projections can distort the relative area from one part of the map to the other, for instance, in the commonly used Mercator projection, the shape of Greenland is preserved, but it appears to be much larger in size than it actually is63

7127156454GISGeographical Information Systems, incorporate one r more data layers in a computer program capable of spatial analysis and mapping, data layers are numerical, coded, and textual data that is attributed to specific geographic coordinates or areas71
