Chorochromatic maps are basically nonquantitative and show phe- nomena by their areal coverage. Their examples of such maps that readily come to
mind include land-use and land-type maps. Agricultural land-use maps, in their most useful forms, are prepared on a fairly large scale, showing individual fields
as they are covered by a single crop or a combination of crops. Urban land-use maps are prepared to show each house, group of houses, or any
other unit of urban space by its func- tion. Land-type maps are based on elements of
and such as geology, geomorphology, soil, and vegetation which characterize different parts of the earth’s surface. The chorochromatic technique
is also applicable in indicating political, cultural, and social characteristics of human populations. For example, ethnological distinctions between
places are usually made by shading each unit area according to the ethnic affinity of its population. Basically, the chorochromatic technique implies
the drawing of bounding lines to delimit specific areas within which shading or coloring is applied to mark distinctive features
