In theory, the site selection problem is as simple as compiling onto a single map all the disqualified areas on the individual maps, and then choosing among whatever qualified locations remain. Although geographers at the time, poo-pood his techniques as being nothing new, because, of course, geographers had been overlaying maps forever, Ian McHarg was the first to consistently make the effort to pull all the information together in a way that they could be related to each other.
