On April 5th, 2006 Google announced My Maps as a new feature that makes it quick and easy to create your own custom Google Maps just by pointing and clicking. It took me this long to figure out why I might be interested in this feature, but I see lots of applications now I have made my own.
According to the news release you can add placemarks, draw lines and shapes, and embed text, photos and videos — all using a simple drag and drop interface. I confirm it is easy. Your map automatically gets a public URL that you can share with your friends and family, or you can also publish your map for inclusion in Google Maps search results.
The Ubertor Real Estate Blog featured this product when it was first announced and wrote a great article about the application and recently published this example of a custom map that could be displayed on a web site.
Here is one I made as an example of how a Realtor or Mortgage Broker could publish a tour of open houses in their area. As you can see it is crude, but it gives the idea.
