Yahoo provides an alternative to the Google Maps approach covered in Parts 1 and 2. You must register with Yahoo before you can use their mapping engine though.
Step 1 - Obtain a Yahoo ID
A Yahoo ID is not the same as your the application ID that you are seeking. If you already have an ID you can skip this step. To register your Yahoo ID, you must choose an account name and supply a password.
Step 2 - Create an Application ID
Once you have a Yahoo ID, you can create multiple Application IDs (or appids) to keep track of the various applications you might want to offer. Yahoo has a tracking service for application ids that is convenient and free! The appid included in the demo code below is the one I created. There is no advantage to avoiding creating an appid of your own because it costs nothing. Also, only I will be able to track what you are doing. If that is what you want, feel free to use my appid:)
You should create an appid for your application now and use it in the code samples that follow.
