  3. Goals & Objectives of Geospatial Data Warehouse Manage Data as a Corporate Asset • Authoritative source • Seamless • Constantly maintained • Current • Accurate • Nationally consistent • Highly available • Business Continuity How do we manage consistent information in 2700+ Offices?

  4. Major Business Requirements for the • Geospatial Data Warehouse • Maintain an infrastructure that provides the authoritative source for integrated USDA geospatial data • Provide on-line access and delivery of geospatial information to current and emerging programs like the Farm Bill and e-government • Provide high availability of geospatial data • Provide a secure data access mechanism that supports information privacy and security requirements • Provide a mechanism for USDA, National, State and Local data to be made available to the general public, to conservation partners and to third party vendors who support conservation planning • Enhance sharing of program and GIS data among Service Center Agencies

  5. GDW Technical Architecture • Geospatial Data Centers • Geospatial Data Production • Geospatial Data Warehousing • Data Delivery (CD-ROM, DVD, FTP) • Data Marts • Data Delivery for Web Applications • High Availability for Public Access • Secure access • Telecomm Architecture • Encrypted VPN Tunnels • High Bandwidth for Distance Replication

  6. Leveraging Existing Enterprise Components • ESRI • Microsoft (Windows 2000, SQL Server 2000) • Veritas • EAI – Web Farms • WAN Telecommunications Infrastructure • USDA OCIO Security

  7. Enterprise Data Storage Architecture (EDARCH) Storage Infrastructure

  8. EDARCH Goals • Business Continuance • Continuous Data Availability • Failover Facilities • Information Protection • Disaster Recovery • Workload Sharing • Collaboration and Cooperation • Tight Integration with the Web Farms

  9. EDARCH Technical Architecture • Closely Integrated with GDW Architecture • Integrated Requirements • Coordinated Architecture • Combined Procurement Specifications • Recovery Capability • Data Replication • Failover of High Priority Applications • Security

  10. EDARCH Architecture Formulation • Build heavily on GDW Design • Consider Optimum Network Connectivity • Involve Application Managers in Requirements • Requirements Analysis • Technical Architecture • Procurement Specification

  14. Web Farms & Data Marts Public Land Survey Soils Hydrologic Units Orthoimagery Common Land Unit Climate Land Use/Cover Digital Raster Graphs Government Units Resource Data Gateway Resource Data Gateway provides Service Centers and the public a “One-Stop” access or gateway to natural resource data including soils, plants, climate, imagery, and maps using the Internet. h Web Farms host web applications and Data Marts serve up data themes and geo-data layers for use within applications or for download via the Gateway. Geospatial Data Warehouses serve as the authoritative source for geospatial resource data used in Service Centers and by the public served up through the Gateway. Data Management and Delivery Geospatial Data Warehouses Web Services Data for Applications Data for the Public • Toolkits CLU • SCIMS e-forms • Loan Eligibility e-FOTG • Soil Data Viewer Performance Measurement • Program Compliance Conservation Easements
