Why was Ian McHarg's overlay method not an accurate method of assessing the landscape? [3], Soon thereafter, McHarg began teaching at the University of Pennsylvania, where he developed the department of landscape architecture, and developed a popular new course, titled Man and Environment in 1957. Ian McHarg (1920-2001) was one of the true pioneers of the environmental movement.

Almost 40 years ago Ian McHarg proposed a bold theory and a set of ecologically based planning methods in Design with Nature (1 969). There are a few people in the history of geography who laid the foundations for the Geographical Information Systems that we have today. In 1968 the landscape architect Ian McHarg published the book "Design With Nature". In Scotland he worked on housing and programs in "new towns", until he was contacted by Dean G. Holmes Perkins from the University of Pennsylvania. McHarg's use of the overlay method, while not resolving this thorny issue, was a forerunner to later forms of complex analysis in multi-criteria route evaluation and decision making.

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.
