A new addition to the Southern Appalachian Information Node (SAIN) Web site allows users to search for and download interactive three-dimensional maps (KML and KMZ files) for use with virtual globe applications such as Google Earth, NASA World Wind, and ESRI ArcGIS Explorer. Over 300 map layers have been added to the NBII resource catalogue to support this area. Although many of the layers are readily available on the Internet, the metadata added during the cataloguing will make it easier for users to identify useful layers.
