Strategic VisionStrategic Vision• Vision
• NRC "Fair Weather" report (2003):• NWS should make its observational data, models, and other products available in Internet-
accessible digital form...the information should be stored in a standard format that can be accessed by the public and used by all those involved in the weather and climate enterprise.
• NWS Strategic Plan for 2005-2010:• Investigate, develop, and expand the use of new technologies in data management and
information systems, such as new internet-based standards and Geographic Information Systems (GIS), to accelerate development and implementation of appropriate NWS and NOAA products and services and to integrate these services in ways that are meaningful to our customers
• Goals:• Take advantage of the power and advantages of using GIS• Consistent NWS Enterprise GIS dissemination• Based on widely used standards (OGC, etc.)• Technology-driven evolution coordinated with partners/users
• Challenges:• Allocating limited NWS resources most effectively• Maintaining consistent dissemination model and ensuring coordinated, orderly evolution

Current Status of GISCurrent Status of GIS• Requirements Process (OSIP) project in system• Many projects: http://weather.gov/gis
• Range of formats, access modes • Experimental services developed at HQ, NCEP, and the field• Many involve collaboration with organizations outside NWS
• Exploring ways to exploit GIS• Verification (Polygon warning, QPE, etc.), next-generation product creation
software, etc.
• Examples of NWS GIS information• RIDGE radar• Warning Polygons• Flood Outlook• NDFD - Fire Weather• Precipitation Estimates• Tropical Cyclones
