Case Study: Enabling Regional Interagency Spatial Data Sharing Using FME
Download as PPTX, PDF1 like230 views
This case study discusses the creation of a regional spatial data sharing system for emergency management within Colorado's North Central All-Hazards region, involving multiple counties. The system utilizes FME and GIS technologies to address diverse data needs, promote inter-county coordination, and provide continuous region-wide datasets. Future steps include expanding data layers, enhancing viewer functionality, and further improving collaboration among counties.

- 2. Agenda Introductions Background and drivers for the project Collecting information Application design System architecture Challenges Benefits Next steps Future applications
- 3. Critigen Safe Software The Colorado North Central All-Hazards Region Member Counties Introductions Boulder Adams ElbertDouglas Clear Creek Broomfield Arapahoe Jefferson Gilpin Denver
- 4. Project Background Emergency management planning focus Need for continuous region-wide dataset Coordination with member counties hard to achieve Homeland Security grant for 2008-2011
- 5. Collecting Information 10 counties, all with different needs, desires, agendas, and data sharing policies
- 6. Collecting Information 10 very different data schemas, from the very simple to the very complex Shapefiles Coverages PGDB
- 7. Collecting Information Everything decided by committee, consensus difficult to reach Prototype application with 8 spatial data layers Roads Parcels Census Blocks Municipalities Lakes Streams Fire stations Schools Plus one non-spatial layer to support one-to-many relationships Parcel Owners
- 8. Collecting Information NCR data schema developed to house translated data sets Feature classes, attributes, and domains need to be mapped and translated

- 22. System Architecture Two servers, one primary, one redundant Hosted at disparate county locations Douglas County – Primary Denver County - Redundant Automated replication between servers XLink ClusterReplica Pro replication software Automated failover between the servers DNS Made Easy
- 23. Challenges Decision by committee Lack of previous coordination between counties Disparities in GIS sophistication Need to better define and monitor uploading schedules for the ten member counties Expanding scope of project to agencies outside of emergency management focus has required: Review of data sharing agreements Modifications to accommodate disparate user groups What to add next… who has what?
- 24. Benefits Unique planning tool with continuous region-wide dataset FME allows quick updates to accommodate provider schema changes FME supports easy expansion of system to include different data inputs (non-spatial) and data schemas “Forced” dialog between counties promotes better coordination Edge matching Data schema consolidation Serves as a model for inter-region and state wide coordination
- 25. Next Steps Phase II wrapping up Added 10 additional data layers Additional user roles – data views Improved existing data layers Phase III starting up Facilitate counties working together to edge match street centerlines Add more viewer functionality Geocoding service Advanced “one-click” spatial queries
- 26. Future Applications Other Colorado all-hazards regions DRCOG and other MPOs State of Colorado
