Helping the World to Communicate Geographically GEOSS Concept Development Project

Helping the World to Communicate Geographically Lessons Learned and Future Works Tremendous enthusiasm and commitment of agencies and research groups to collaborate Demo provides a fast-track to skills development and knowledge transfer. GEOSS application-specific demos are a great way to engage with user communities that would not necessarily look to OGC standards. Live demo is “probably” not the best means of communication – targeted descriptive piece should accompany presentation which may be pre-recorded demo Communication networks are not reliable at workshops Need clear message about using distributed components with open standards, vs., standalone application Demo needs to be “persistent”

GEOSS Workshop/OGC Demo at ISPRS Commission IV Symposium 26 September, Goa, India Jeremy Morley University College of London

Helping the World to Communicate Geographically GEOSS/OGC/ISRO Workshop Revised Agenda, June 10,2006

Helping the World to Communicate Geographically Goa demo - initial ideas Theme: public health in India, e.g., water quality Perhaps: Demo looking at public health reporting using a PDA, communicating live over a low-bandwidth link. Use of OGC specs-based demonstrator for using PDAs & low-bandwidth (telecom) links for in-field GIS. Perhaps a combination of WMS, GeoRSS and WFS-T for sensor data on a PDA? How to demonstrate a PDA to large audience?

Persistent Demonstration Capability of OGC Network

Helping the World to Communicate Geographically Persistent Demonstration Capability of OGC Network OGC Network web pages –Purpose: For information, For access to demo –Example from Rudy - Pre-recorded demo playback –Creating files screen captures –Where to host the large flash, avi files - need for guidelines, e.g. frame rate, posted to OGC Network Live demo from OGC network –Web browser clients –Application clients, download and install on user machine: executables and open source; –Scripts: instructions, descriptions, urls Persistent servers Use case development, e.g., Galeon - Ben –From go to create content->Use Casehttp:// or: –Example from Stefano

Helping the World to Communicate Geographically

Helping the World to Communicate Geographically Persistent Servers on OGC Network Important to establish expectations of server providers to accomplish reliable persistence Length of commitment –Upon registering a service with the Network, a service provider must specify the length of time for which the service will be offered (preferably ‘unlimited’). –Consider multiple years Level of service –services are expected to be available at least 99% of the time, except when otherwise required by the nature of the service. –This allows for approximately 7 hours of down time a month –Being achieved regularly by servers, Biggest problem is network provider Termination –OGC may “de-list” a server from OGC Network –non-functioning components of the Network will diminish the operational and marketing value of the Network in general for all participating organizations.
