Google Earth Enterprise  DC will have its own Google Earth “Globe”  Available on the DC WAN with the Google Earth Enterprise Client  Available on the internet in Google Maps applications  Google Earth Enterprise Components  Google Earth Fusion to store, style, and organize data into a seamless viewable globe or 2D browsable map  Google Earth Server to host and stream data to end user software  Google Earth Enterprise Client or Browser-based 2D Maps view for viewing, printing, searching and data authoring

Google Earth Fusion  Supports imagery, terrain, polygons, points, lines, KML, regionated KML overlays, and 3D models  Supports distributed data processing across multiple CPUs and machines  Easy-to-use GUI or scriptable interface to automate data ingestion and database completion  Project metaphor – create projects for different collections of data and use these projects to build multiple 3D globes or 2D browser-based maps  Auto-ingest – scriptable engine to automatically sync with changing datastores  Built-in projection handling  Virtual mosaicking capability  Rich styling support in GUI to create themes in vector data  Support for common raster and vector data formats  KML streaming  Support for KML Support for KML  Google SketchUp Models Google SketchUp  Superoverlay Image processing  Vector and Point  ESRI Shapefile (.SHP)  MapInfo Tab (.TAB)  Comma Separated Values (.CSV)  Image and Terrain  GeoTIFF, Erdas IMG, JPEG2000, MrSID (32-bit version only)  TIFF, JPEG, GIF, PNG, BIL, BIP  DTED, USGS SDTS DEM, ASCII DEM

Issues we are working through  Meant for world wide mapping  Built in zoom level not to local government scale  How can I stop it from starting the map over California?  How can it start up zoomed to DC?  Unable to change the display order  Needs more symbols

DC budget so far  Purchase from GSA vender  $25,000 for Google Maps Enterprise  2,500,000 hits per year  $100,000 for hardware / software bundle for Google Earth Enterprise
