The land-use suitability analysis (LUSA), is a method popularized by Ian McHarg's seminal work, Design with Nature, originally published in 1969. Overlay analysis is a common method for creating a suitability model which involves using GIS techniques and software. Never before had the complexities of the relationship of land use .

Why was Ian McHarg's overlay method not an accurate method of assessing the landscape? In theory, the site selection problem is as simple as compiling onto a single map all the disqualified areas on the individual maps, and then choosing among whatever qualified locations remain. His experiences helped him see the link between health, happiness and environment, and he concludes that, we need, not only a better view of man and nature, but a working method by which the least of us can ensure that the product of his works is not more despoliation (p.5), Ian McHarg, 1967, Design With Nature, John Wiley and Sons.
