Organizations can publish and
integrate their geospatial data
services…
Rather than making copies of data, using SOA organizations can
continue to maintain their own data bases while offering access
to these as web services that can be used by any number of
desktop GIS clients and Internet map viewers.

Suggested changes communicated
back to data “owners” and they decide
whether to accept or reject. Changes
made to source databases and
propagated back to GeoCommons.
Org 1
Members should be able to:
• See all layers including other proposed
changes
• Select objects from Master to change
• Import shapefile into Edit layer
• Import GPS coordinates into Edit layer
• Do heads up digitizing in Edit layer
• Edit copy of attributes
Information on action taken on
suggested edits communicated
back to the GeoCommons.
