Google Maps API, AJAX and the running tool

After my sour grapes last week I decided to dig in to regain pole position for innovation with online pedometer tools so I spent the weekend upgrading WalkJogRun.net to create a running community.  The key feature is the ability to add routes to the tool for all to share.  Here are the highlights:

  • User community can add their own routes and save them to the system for later retrieval and also for others to view
  • Maps now use the Google Maps API so no need to copy the URL of a map you want any more to use the tool.  I've also included a revision history so you can look at some of the older versions
  • England supported!  I was browsing around the world last night and I realized that the Google Maps include England and the UK now. I've added cities I have a history with as quick links but will be adding more. 
  • I used AJAX to retrieve routes as an XML packet of longitude an latitude nodes. 
  • AJAX also features in the address lookup feature to allow you to quickly move from one area of the country to your starting street address.  Without reloading the whole page, I query the US census bureau's public domain TIGER data to get Longitude and Latitude for a given address
  • Each leg of your journey has an estimated duration (based on current speed) and mileage.
  • Each route can be annotated to describe the route, for instance to explain how hilly or how much traffic exists for a given route.

I'm working on a registration process so you can have a "My Routes" section and customize your experience.  Currently any routes are saved under the username Guest.

As always, let me know what you think and I'll try to accomodate requests.

  1. Adam, you deserve some recognition! I am going to link you from Walking.About.com which is the most popular web home of walkers. If you can stand us slowpokes, we'll be by.

  2. How about a parallel category for bike routes? This works just as well for sharing bike routes.
