The overlay mapping method is insufficient by itself because it assumes all attributes to be linearly independent (Hopkins 1977). Prof. McHarg, who practices city planning as a landscape architect, classifies ecological factors such as climate, physiography, geology, hydrology, soil, vegetation, wildlife, and historical landmarks in terms of value criteria; makes spatial maps displaying various ecological values;and combines them with an overlay method by means of which .

Always a polemicist, McHarg set his thinking in radical opposition to what he argued was the arrogant and destructive heritage of urban-industrial modernity, a style he described as "Dominate and Destroy.". Storing digital data in multiple "layers" is not unique to GIS, of course; computer-aided design (CAD) packages and even spreadsheets also support layering. To do that, he developed an eligibility analysis through a technique he called "overlay mapping". This community was developed from timberland located thirty miles north of Houston, by George P.

McHarg pioneered the use of map overlays to highlight intrinsic natural features, that commonly included flood zones, wetlands, woody vegetation stands, slopes, drainages, aquifer recharge zones, areas under cultivation and man-made features.
