Relief & Rehabilitation Efforts:Lessons learned
• Demands for accessible maps were very high
• Maps were used mainly by individual and groups during relief efforts processes
• Maps were also used by government agencies to show the relief and rehabilitation progresses

•Maps were everywhere, but mainly treated as a media to make report not yet as a media to support coordination & collaboration efforts

Group Work Intensity• Cooperation
Group interaction is done through information or resources sharing during the work phases.
• CoordinationGroup interaction is done through job delegation and then share the results.
• Collaboration Group interaction is done through team work and synchronization of the results.

Geocollaboration Portal
Spesifications:- Spatial data are assumed to be stored and served by
local agencies as Web Map Services (WMS) or WFS- Those layers can be cascaded and overlaid- The collaborative analysis among the group members is
facilitated through discussions on top of spatial features
![Page 18: A GeoCollaboration Portal for a Local Geospatial Data ... fileTrias Aditya (triasaditya@ugm.ac.id) ... • Geospatial Data Infrastructure for DM: Inaccessible & Inoperative.

GeoCollaboration Portal
• Create annotated marker, line, and polygon using user color
• Information synchronization
• Discussions are managed in sessions
• A Session can be saved for further/next interaction
• Integrate spatial layers (Web Map Services, Web Fearure Services, KML) distributed across the agency servers within the region.
• Discussion is limited to only face-to-face or distributed meeting with voice/chat messenger

GeoCollaboration Portal
Web Map Services :- Mapserver Open Source - Spatial data are stored as shapefiles not yet as PostGIS/MySQLShared Visualization:- Server (mapserver) – Client (portal incl. Google Maps): AJAX
[Asynchronous JavaScript & XML]- Collaboration Mode: ‘Periodic Refresh’ [update after 5”]- Activity & collaborator profiles are stored

Workshop
• Get disaster management stakeholders involved & aware of the portal
• 80 Participants from various institutions!
• Speakers: Bapenas, BID, and researchers

Discussions
• On-the-Fly Spatial Analysis like buffering on top of the portal can further the potential use of Collaborative GIS for disaster management
• The cognitive and organizational aspect of the group members in the group interactions have not been considered in the portal design.

Conclusions
• GeoCollaboration Portal is considered of useful and urgently required at local agencies
• GeoCollaboration portal can be used to improve coordination & group work in disaster management activities
• Collaborative Portal is a crucial milestone for local agencies to make Geospatial Data Infrastructure accessible & operative
