Nor are landscape architects significant users of Geographical Information Systems (GIS). The analytical hierarchy process (AHP) was used to produce weights for the six criteria considered, which were then reclassified . Landscape architects now agree that both artistic and scientific inputs are essential. In his landmark book, Design with Nature (1967), the American landscape architect Ian McHarg described the use of map overlays as a tool for urban and environmental planning. There are some critics, however, that take issue with McHarg's methods as being too much of a hard science, a lack of artistic expression, and the role of landscape architects as analysts rather than creators.

Prof. McHarg, who practices city planning as a landscape architect, classifies ecological factors such as climate, physiography, geology, hydrology, soil, vegetation, wildlife, and historical landmarks in terms of value criteria; makes spatial maps displaying various ecological values;and combines them with an overlay method by means of which . This is the least textbook-like of all the textbooks I have ever read. 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.
