"tradition of Ian McHarg, Phil Lewis and Warren Manning"

"Obviously, one problem was to deal with more than one map, right? What’s the topology like when you have more than one map? Well, you’ve got to overlay them. We knew that was the trick because why else did Sinton have to use GRID as opposed to SYMAP? It’s because the students in the Landscape Architecture tradition of Ian McHarg, Phil Lewis and Warren Manning wanted to overlay and interact different maps. Sinton used GRID to integrate the sources."
