20. Helping the World to Communicate Geographically © 2007, Open Geospatial Consortium, Inc.20 What to watch for in the demonstrations How the components inter-operate –Services are distributed; not a monolithic workstation application –Services are interchangeable; plug & play using standard interfaces –Adherence to GEOSS architecture requirements Why it matters to GEOSS users –Easy, quick access to data: dramatic reduction in effort and time –Agile, flexible workflow allowing evaluation of different approaches –Enables collaboration: services accessed by variety of users –Pragmatic decision support
