A recent study by Landscape Architecture Magazine was published in the March 2012 issue.
44 college landscape architecture programs responded to questions about software taught to students during their curriculum.
And the answers are:
Adobe Photoshop
AutoCAD (by Autodesk)
Google Sketchup
What software have any of you found useful/pertinent to landscape design? Any suggestions?
