About five years ago, when I was working at the Star, someone in the graphics department had the idea of mapping the GTA’s census tracts by the top language other than English, based on the 2006 census. It made a fine double-page map feature in print, but the only way we could think of to present it on the Web was by uploading the page proof, which was a .pdf weighing in at 25MB or so. There has to be a better way, I thought, which started me on this whole map business. (Whether there was a better way was debatable, since it would be another couple of years before we figured out how to handle large numbers of polygons more or less painlessly, or get access to them by some method other than hand-drawing them in Google Earth.)
So it’s nice to be able to present an interactive Google Maps-based map of the GTA’s census tracts by the top language other than English, based on the 2011 census (I may go back and do prior years – we have the data). We have Toronto, as well as 14 other Canadian cities.
