With the help of Stephen Paul Weber, I have created a web-based tool that plots Canadian automated banking machines (ABMs) using Google Maps, which is called ABM Locator. The first version of this tool (0.1) has just been released. I suggest viewing the live demo if you’re interested in seeing it work.
You can get the source code from the Download section of the ABM Locator project page or check it out from Subversion (also on the project page). Please send any comments, questions, bug reports, etc. to the mailing list.
