  2. Why use Google Geospatial Technology • Market Share • Our customers know how and want to use it • Our decision makers want it • DC Mayor and Chief Technology Officer have entered into a partnership with Google. • Google Maps API lowers development and data costs • Google Earth 3D capability -- Primary Concerns – • Advertising • Does not replace data maintenance or analysis from our ESRI suite so we are supporting an additional environment.

  3. DC GIS Data Downloads Now Available in KML http://dcgis.dc.gov

  4. Google Maps

  5. Google Maps DC Samples DOT Evacuation Routes DDOT Snow Response DCPS School Finder FEMS Hydrants

  6. 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

  7. 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 • Google SketchUp Models • 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

  8. 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

  9. 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
