Geographic Information Systems technology, like GPS and online mapping tools, took centre stage at GIS Day, hosted by Carleton University’s Department of Geography and Environmental Studies.

GIS Day organizer Steve Prashker, a department instructor, also revealed his talents as a “map wizard,” master of secrets for folding maps for compactness and ease of retrieval.

“If you take your typical Ontario road map, and you open it up and try to fold it back, you can usually never get it back the way it was originally folded,” he said. “These are some of the techniques that make it easier.”

Among his techniques is the Miura map fold, named for Japanese astrophysicist Koryo Miura and used to fold solar panel arrays on satellites. It’s also great for maps.
