The land-use suitability analysis (LUSA), is a method popularized by Ian McHarg's seminal work, Design with Nature, originally published in 1969. . Map Overlay is important functionality in any GISthat is the ability to overlay multiple maps onto each other so that new understanding of an area can be gained based on the relationship between the maps. He was admitted to the school of architecture at Harvard University's Graduate School of Design where he received professional degrees in both landscape architecture and city planning in 1949. McHarg was enthusiastic about this project, and greatly invested in the work. With the advancement of computer mapping software, suitability modeling has become much easier and faster to implement, and today it is used for many varying tasks. The analytical hierarchy process (AHP) was used to produce weights for the six criteria considered, which were then reclassified .

Its mission is to build on The Weitzman School's position as a global leader in urban ecological design by bringing environmental and social scientists together with planners, designers, policy-makers, and communities to develop practical, innovative ways of improving the quality of life in the places most vulnerable to the effects of climate change.[16]. Graphic - McHarg used blacked-out transparent overlays for site selection in Design with Nature. In 1963 Ian McHarg and David A.

Instead, he saw the earlier tradition as a precursor of his philosophy, which was rooted less in aristocratic estate design or even garden design and more broadly in an ecological sensibility that accepted the interwoven worlds of the human and the natural, and sought to more fully and intelligently design human environments in concert with the conditions of setting, climate and environment.
