The GIS/PortlandMaps.com team at the City of Portland is proud to announce our new dynamic mapping service with 25 data layers including:

Using ESRI GIS tools on the backend, and KML's NetworkLink technology, we have been able to transfer much of our existing online map services that are available on PortlandMaps.com into Google Earth. All the layers in our new GE service are served live from our existing SDE database. GroundOverlay layers are rendered on-the-fly using ArcServer.

We are excited about the new Google Earth technology, and it's ability to be extended using KML. Thank you Keyhole/Google for supplying this great new GIS client and making it free.
