3 Enhancing resilience against multiple hazards using innovative spatial data architectures: a modern view of the relationship between GIS and database technology Arthur J. Lembo, Jr.; Ph.D. Cornell University

4 Goals for GIS-based Rapid Response to Extreme Events How do we harness powerful geospatial tools in response to multi-hazard events? How do we leverage and integrate leading technological innovations within our response to multi-hazard events? How do we seamlessly distribute our geospatial solutions for multi-hazard events within multiple, heterogeneous entities? How do we deploy these solutions to users in the immediate aftermath of mult-hazard events?

5 Windows applications Spatial databases Real-time data monitoring site GIS Open GIS data sources GIS and Internet Access Large Image Servers

6 Leverage other windows based applications Excel, Access, others.. Oracle, DB2, SQLServer Integration with other geospatial tools Microsoft MapPoint Oracle Spatial High level tools for data manipulation cut and paste between applications, etc.. Integration with computer operating system and applications

7 Treating Geography as a Database Object The database ecosystem completely dwarfs the GIS ecosystem (and Nintendo is bigger than everyone!) Treating geographic objects as true database records taps into the larger, and technologically superior industry Why not SQL! Revisited..

8 Spatial SQL in a rapid response system PARAMETERS [Enter Building Damage State] integer; SELECT * FROM [Building Inspections] WHERE BldgDmgState = [Enter Building Damage State] PARAMETERS [Enter Building Damage State] integer; SELECT [Building Inspections].* FROM [Building Inspections], FEMA WHERE CONTAINS(FEMA.ID,[Building Inspections].ID) AND BldgDmgState = [Enter Building Damage State]

9 Geometry Manipulation with SQL

10 Most IMS applications require separate middleware software, divorced from the main GIS application. Integrating the desktop with the Internet Internal Internet Map Server Architecture Manifold GIS integrates the map server and GIS in a single application for under $250. Data, queries, and thematic rendering created in the GIS is immediately available to Internet users.

12 Integration with Google, Yahoo!, Microsoft OGC Web Mapping (WMS/WFS) Integrating the desktop with the Internet Leveraging external data sources (Web Mapping and Open Source Standards)

13 Microsoft Excel Query allows dynamic access to HTML pages Data may be stored in Excel, and features dynamically create in Manifold GIS. Data can then be republished on the Internet to create a dynamic map. All without any programming Integrating the desktop with the Internet Leveraging external data sources (databases) USGS Webpage Displays realtime data Excel Spreadsheet Reads USGS webpage Manifold GIS Reads Excel spreadsheet

20 Next Frontier Reducing Response Time to Hours Tighter GUI SQL Based Query System Rapid Development Enterprise Sharing of GIS Data

21 Conclusion Modern GIS architectures using leadingedge computer and database technology opens the door to resourceful solutions that exploit 3 rd party data sources and applications Treating geography as a database object leverages a mature database ecosystem for developing robust applications. Mature database management tools integrated with GIS and networking tools allow for redundant, distributed systems in heterogeneous environments
