Content Management System (CMS) as DSS
Web-Based CMS’s are Built to:• Aggregate Multi-User Content• Manage User Access• Promote Collaboration• Organize Information
Data is Content• Blogs, Video, Social Media harder than #’s• Don’t Reinvent the Wheel (Re-engineer it)
Geo-Spatial CMS (GeoCMS) Adds• Spatial Analysis• Spatial Linking of data (GeoSpatial Hyperlink)• Geographic Info as Organizational Tool
DSS Overview:Virginia

Built to Integrate and Evolve
Drupal is a Highly Configurable Content Management System• Modularity, support, and robust
framework• Coupling – many tools for data
export/import• Modules Used: Views, Feeds,
Charts, GeoField• Easily Integrated with VAHydro
Modeling system
Conclusions
Decision Support is 90% Organization / 10% Inspiration• Sweat the details• Analysis is easy if the
organization is solid Why CMS: Collaboration is Key
• Data Sharing IS QA• More Eyes = More Ideas• CMS’s Are Best of Breed Tools for
Sharing/Collaboration Why Web-Based GeoCMS’s are
Needed:• Data is Content• GeoCMS’s bridge skill gap
