DC GIS Use of Google Geospatial Technology MWGOG GIS CommitteeJanuary 14, 2008


Why use google geospatial technology l.jpg
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.

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

      • TIFF, JPEG, GIF, PNG, BIL, BIP

      • DTED, USGS SDTS DEM, ASCII DEM


Issues we are working through l.jpg
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 l.jpg
DC budget so far
