134 Part II — Instant Gratification
Integrating the original street map with an overlay of the transit map can make understanding
the information much easier. Figure 8-1 shows an example of a Google Map overlaid with
the TTC subway map. You can find this example online at http://crazedmonkey.com/
ttcgooglemap/. It provides route and station information for the whole of the Toronto
subway system.FIGURE8-1: A Google Map overlaid by the TTC subway map.The map is split into two parts. On the left is a map, which is (obviously) the Google Maps
component. You can see the markers showing the individual stations and their locations on the
map. You can also see the route of the transit line, in an appropriate color, behind the stations.
On the right is the list of stations, colored according to the color of the line on the official
TTC map.Because the map is interactive, you can zoom right in to the location of the station to find out
exactly where the station is located, and you can find out the precise details by clicking on one
of the stations, as shown in Figure 8-2.FIGURE8-2: Viewing station information.
