Greater Toronto Area transit map

Many years ago, when Google first released Google Maps and revolutionized online mapping from the stagnant MapQuest era, I put together a few quick demos showing the Vancouver and Toronto transit maps. I’ve made a few updates over the years since then, but not much more.  The Vancouver one is still quite popular – more popular than TransLink’s own map, to be honest – but other web gurus made better Toronto maps, such as the excellent one by Ian Stevens.

I’ve noticed that Google has revamped the mapping APIs and is preparing to eliminate version 2.0. The whole treatment of online mapping is changing rapidly, as the mobile market takes off. I was thinking of just scrapping the Toronto map since it’s not well-used – but then I thought a little further. What if I could make a proper map of the Greater Toronto Area?  Ian’s map doesn’t cover that – in fact, since there isn’t even a good print product covering the full area. Perhaps I could make something useful for the “regional traveller” using GO, and also help mobile users who have trouble with Ian’s site.

I set to work, borrowing liberally from others. It’s a patchwork by nature, since each agency has its own colour and line conventions, but hopefully still useful. When Ian made his map, taking a bitmap image and turning it into tiles was a bleeding-edge endeavour and required painstaking effort – but the tools have improved a lot. Even still, a bitmap this size (35,000 pixels square) takes some horsepower. I didn’t have the energy to do everything Ian did (like removing the background); his map will still probably work better for most TTC riders. I also couldn’t figure out what map projection Oakville Transit used, and couldn’t get it to line up nicely with the other data.

I’ll probably do a few more revisions on this in the next few months – an adjustable opacity slider would be nice, a legend for each operator, and higher zoom levels. But I thought I’d release a beta version and see if anyone likes it, and see how expensive the bandwidth is.

Version 3 of my map is now up (and version 2 is still around for anyone who wants it). New in this version:

  • Local transit operator maps
  • More mobile friendly: full-screen view by default, location-aware (uses GPS to detect your current location, if available)
  • May seem slower, unless you have a new browser, like Google Chrome or Firefox 4
  • Graphics updates: labels cleaner, interchange stations cleaner, labels always visible instead of showing on hover (for touchscreen users)
  • Search tries to find a transit station first, otherwise tries other non-transit locations
  • No legend… yet
  • Added “Get directions to here” link to each station
  • API version 3
  • Fixes: added Lincolnville station, fixed broken links

  1. Nice work David. Metrolinx is lucky to have someone with your range of skills – and you actually keep them fresh!

  2. I’ve now tested this on an iPhone 4 and iPad 2 – and it seems to work very nicely, slick interaction with only one or two quirks. Yay Google – good job making a mobile-friendly API!
