Delivery Models and Implications

• Concepts
• provider and consumer
• request and response.

• At the core are Web services and XML

Spatial Business Services

• The spatial business functions live here

• These functions include services like
• Geocoding
• Proximity (e.g., closest hospital)
• Routing / network analysis / Tracing
• Image Services / Maps
• Intersect / Union (e.g., SBE)

12
Scalable and Extensible

• As use increases we scale out

• As business requirements change, we extend
  current functionality
• Geocode my address and tell me what services are
  available (power/gas/cable/etc.)
• Also, return an image to me with these things and
  my location.

13
Business Continuity
Fault-tolerance and load-balancing are built
into critical architecture components
Coupled with a highly-available storage
infrastructure, business continuity is maintained

Virginia Base Mapping Program (VBMP)
Program Goal Establish and maintain seamless
statewide base data in GIS that can accurately
and efficiently support local, regional, and
statewide geospatial applications.

• Products
• Imagery (Digital Orthophotography)
• Roads (Addressed and Non-addressed)
• Hydrography (Rivers and Streams)
• Railroads
• Digital Terrain Model (DTM)

Virginia Base Mapping Program (VBMP)

• VBMP Roads Program
• Seamless consistent statewide geometry based on
  imagery and incorporating local segmentation
• Includes all public and private vehicular
  traveled roads
• Comprehensive and consistent addressing
  attributes
• Is current to a schedule that meets public safety
  and local needs
