How to Mashup Google Maps

Google Maps allows you to create maps providing directions from one location to another. You can save these maps for future use. When you save a map, it can be exported to the KMS format and saved on your computer's hard drive. Once the file has been formatted to KMS, you can import one map into another, combining the two and viewing the information in both maps.
