‘Data for Decision’: GIS on Punchcards
“Data for Decision” is a 1967 National Film Board of Canada film that explains the work of the Canada Geographic Information System — one of the earliest GISes in history, if not the earliest — in analysing the huge volumes of data from the Canada Land Inventory. It’s been uploaded to YouTube in three parts: part one is above; here are links to parts two and three. A dry documentary (today it would have been a PowerPoint presentation at a high-level bureaucratic meeting), but now it’s a fascinating look at GIS in the punchcard era.
