Ian McHarg at Penn, pioneered the method of overlaying transparencies about suitability criteria, which then got translated into GIS with the advent of computers. In a passage describing the process he and his colleagues used to determine the least destructive route for a new roadway, McHarg (1971) wrote: As you probably know, this process has become known as map overlay.

In 1963 Ian McHarg and David A. Wallace, his academic colleague from the University of Pennsylvania, founded the firm of Wallace and McHarg Associates, later Wallace McHarg Roberts & Todd (WMRT) which is known for its central role in the development of the American environmental planning and urbanism movements. [9], McHarg was the recipient of numerous awards, including the Harvard Lifetime Achievement Award, the Pioneer Award from the American Institute of Certified Planners, and 15 medals,[10] including the 1990 National Medal of Arts,[11] the American Society of Landscape Architects Medal, and the Thomas Jefferson Foundation Medal in Architecture from the University of Virginia. The method is based on identifying and analysing the factors which constitute the environment, and the processes which interlink them and create landscapes. he published the landmark influential book Design With Nature which The basis of his method is not to ask where something should go, but to identify where it shouldn't go.

Why was Ian McHarg's overlay method not an accurate method of assessing the landscape? In the vector case, often referred to as polygon overlay, the intersection of two or more data layers produces new features (polygons). Part of the explanation is that the overlay method was unbalanced to the extent of being flawed. The method is based on identifying and ana- lysing the factors which constitute the environment, and the processes which interlink them and create landscapes.

Landscape architects now agree that both artistic and scientific inputs are essential. He was also instrumental in the founding of Earth Week, and participated on task forces on environmental issues for the Kennedy, Johnson, Nixon, and Carter administrations[14]. These sliver polygons arise from inconsistencies and inaccuracies in the digitized data. The output from the prescribed critical diagnostic analysis, performatively constructed with the help of graphic transparency, is referred to as "X-rays" (1969, 35).
