I participated in a great GIS Day event yesterday, but it left me pretty exhausted by the time I got home, so no blog entry.
Today, we can talk about KML. KML is a set of data is a specific XML format that represents geographic locations. So, what can you do with it? You can take information from a database, get it geocoded and output it to a KML file. You can then send the file to Google Earth or any other mapping service that understands KML, and all those locations will display on the map. You can map all your group members, customers, offices, work sites or even the location of all your vacation photos. You don't need to buy mapping software or set up your own server. Your data is dynamic, so your map is dynamic. Add a new work order and it shows up on your map.
