In the video I tell the beginning of the story of how to overlay maps. Environmental scientists and engineers consider many geological, climatological, hydrological, and surface and subsurface land use criteria to determine whether a plot of land is suitable or unsuitable for a LLRW facility. This system of overlays is a crucial element of GIS, which uses digital map layers rather than the transparent plastic sheets of McHarg's day. With the advancement of computer mapping software, suitability .

One problem with vector overlay is the possible generation of sliver polygons. Founder of the department of landscape architecture at the University of Pennsylvania. McHarg grounded his theory and methods in the science of ecology and pursued this approach in many projects, including The Woodlands planned community in Texas. [6] The park was to demonstrate the heritage of the Iranian people, as well as to illustrate the major ecosystems of the world. his philosophy of incorporating environmental concerns into designs, leading to Ian McHarg's Design with Nature (1969) popularized notions of interaction of natural systems & "spatial analysis" McHarg, a landscape architect and planner, popularized the method of map overlay using manual techniques.

[4] The course featured leading scholars whom McHarg invited to his class to discuss ethics and values, as well as other ideas ranging from entropy to plate tectonics. 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 favoured what became known as 'cluster development' with relatively dense housing set in a larger natural environment. 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.".
