  1. CapStat GIS Overview September 22, 2005

  2. Agenda • CapStat Project Introduction • Technology Overview • GIS Issues • GIS Committee relationships • Demonstration • Discussion

  3. What is CapStat? • A project to develop an interoperable infrastructure for data exchange • A concept for the interoperable architecture & suite of web services • Technology to implement the architecture & web services (ESB, GIS, Fast Data Search) • Joint effort among DC & NCR jurisdictions • Funded by a DHS grant of $976K • Completed by March 2006

  4. Project Scope • Establish secure network that enables applications to work together and exchange information on regional basis – regional Enterprise Service Bus (ESB) • Connect the District and selected NCR partners using this regional network • Publish seamless GIS situation map of NCR with coordinated content from CapStat partners • Post relevant E-911 incident calls to shared NCR GIS situation map on real-time basis • Publish situation notification: news and weather alerts with content collected from databases, web sites (e.g. NOAA) and syndicated news wires

  5. DHS/Emergency Issues & Requirements • Security • Authentication • Real time data management • Managed routing • Guaranteed delivery • Penetrate firewalls • Emergency data exchange vs public web service

  6. Interface Web Services Messaging XML Schema Delivery Network Governance, Semantics Service Oriented Architecture ESRI ArcIMSWeb Feature Service SonicEnterpriseService Bus GML, NIEM, NCR &Jurisdiction Schemas

  7. Business Value of SOA • Broaden business integration – partners • Deepen business integration – outsourcing • Reduce data communication cost • Faster process change • Reduce cost of change • Accommodate uneven rates of change • Speed!

  8. What are Web Services? • Application component interfaces that: • Communicate via open protocols (HTTP, SMTP, etc) • Process XML messages framed using SOAP • Describe its message using XML schema • Provide an endpoint description using WSDL • Can be discovered using UDDI • Standalone service

  9. XML • eXtensible Markup Language • Provides a universal data format that lets data be easily adapted or transformed • Example: • <?xml version="1.0" encoding="UTF-8"?> • <addr1 version=“1.0"> • <request type="validate"> • <ADDRESS> • <BLDGNUM>1350</BLDGNUM> • <STREETNAME>Pennsylvania Ave</STREETNAME> • <QUAD>NW</QUAD> • </ADDRESS> • </request> • </addr1>

  10. GML • XML based language for exchange of geographic data • Uses XML schemas to define the geometry elements needed to encode geographic elements • Supports spatial & non-spatial properties • Works on browser • Custom map styling • Editable maps • Sophisticated linking capabilities

  11. What is an Enterprise Service Bus (ESB)? • Standards-based integration platform that enables applications to reliably work together and exchange information • Support for legacy applications • Sonic ESB services • Message quality of service • Intelligent routing • Data transformation

  12.

  15. Example Regional Services • Enterprise Search Engine • Web sites, Media feeds (RSS), District databases • Alert generation: triggers, actionable information • EPA Hazmat data • Weather observations • District 311/911 data • District address validation • Spatial services: radius search, nearest neighbor

  16. SOA Benefits to Regional Interoperability • Publish services • Publish data “as is”, transforming • Content meaning • Versions • Owner controls access, distribution • Security, authentication, encryption • Guaranteed message delivery • Traverse firewalls

  17. How Fast Can Government Respond? • How fast can government… • Move resources where needed? • Make a decision when asked? • Engage teamwork when needed? • Change course when needed?

  18. Emergency GIS Operations • “Normal” pre-event data exchange (MEDS) • Periodic exchanges • Ad-hoc requests • Emergency event operations: • Updates to pre-event data • Real time event data • Real time additional data acquisition

  19. General GIS Use Cases • Publish GIS data for external use • Download/access data form other jurisdiction • Push update data to another jurisdiction • Request data from another jurisdiction • Exchange event report/situation data • Exchange data for real time collaboration • Monitor location of event data to recognize alert condition

  20. GIS Issues • ESRI software relationships • Map/image service, feature/vector service • OGC-GML (2, 3.0/1), catalog standards • NIEM standards • MEDS determination • Real time emergency event data • Compose map from multiple GMLs • Consume external jurisdiction data

  21. Related Projects & Systems • National Capital Region Interoperability Program-overall interoperability throughout the region • WebEOC system-widely used incident management system with GIS interface • Maryland EMMA/MEGIN capabilities-ESB handle actual data movement

  22. GIS Committee Roles • Determine MEDS content • Determine GIS exchange processes, rules, policies • Agree upon standards • Establish web service development methods • Share development responsibilities • Participate in ESB & web service training

  23. Jurisdiction Roles • Determine web services to be provided to NCR • Develop jurisdiction web services • Publish jurisdiction GIS data • Consume external data in jurisdiction applications • Determine ESB administration parameters

  24. Demonstration Scenario • Introduce & show Mobile View application • Describe Mobile View-ESB relationship & highlights • Examples of diagrams & code of ESB operation

  25. About MobileView • Objective: Provide mobile workers in the District access to strategic DCStat data and services • Integrates databases from multiple agencies : • Property owners, tax and vacant housing • Housing complaints • Citations for housing violations • Resident requests for city services • Crime incidents • Search and GIS spatial analysis functions • Optimized for Microsoft PocketPC PDA over wireless connection

  26. MobileView Demonstration

  27. Bus Process Orchestration • Application services • Message channels (queues & endpoints) • Intelligent routing rules • Message transformations

  28. Intelligent Routing • Eliminates need to return to broker between process steps • Route messages through applications based on message body content • Transform Message • Reshape message content between MobileView XML document message and signatures expected by web services • Filtering, security • Demo example includes both .NET and Java web services

  29. Transformation • Mobile View employs Mini-MAR address validation service and database • DC has a new MAR V1 validation service and database now available • Without changing the Mobile View application the EBS can transform the validation request from the Mini-MAR to MAR • Example address not present in Mini-MAR database now available in MAR
