He was searching for the optimum route for a new highway that would be associated with suburban development. 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 .

Pellentesque dapibus efficitur laoreet. 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. His early experiences with the bifurcated landscapes of Scotlandthe smoky industrial urbanism of Glasgow and the sublimity of the surrounding environshad a profound influence on his later thinking. Arguably the two most significant historic situations that must be taken into consideration by the mapping practices of Ian McHarg and the projects that actually brought GIS into fruition. is a method popularized by Ian McHarg's seminal work, Design with Nature, originally published in 1969.

McHarg's original LUSA, was a spatial overlay technique in which social and environmental variables of the region of interest were gathered and McHarg developed the method in the 1960s when his firm, Wallace McHarg Roberts & Todd, specialised in consulting on highway and parkway route selection, resulting in two principal studies, A Comprehensive highway route . rocks to farm the land, to wet to grow pine trees for lumber, too steep He was the founder of the department of landscape architecture at the University of Pennsylvania.

Born near the gritty, industrial Scottish city of Glasgow, he gained an early appreciation of the need for cities to better accommodate the qualities of the natural environment that until then had largely been shunned.
