  1. RIDGE – The New National Weather Service Radar Webpages Keith Stellman National Weather Service Southern Region HQ

  2. RIDGE (Radar Integrated Display with Geospatial Elements) • RIDGE Background • RIDGE Examples • RIDGE Future NWS SOUTHERN REGION www.srh.weather.gov

  3. New NWS GIS Radar Webpages • Available as time loops for ALL Weather Service Radars • Radar images and warnings are GIS ready • Adds NWS warnings to the display • Calculate distance from a storm and determine Latitude/Longitude • Provides real time radar reflectivity, precipitation and now, velocity data! www.srh.weather.gov/ridge NWS SOUTHERN REGION www.srh.weather.gov

  4. Radar Background • Current displays are: • Showing their age • Difficult to update (especially the roads) • Have not been updated in over four years • Technical issues • TOC over capacity has degraded timeliness • Some products not produced during high load periods • Architecture has several single points of failure NWS SOUTHERN REGION www.srh.weather.gov

  5. Radar Background • Current web radar displays are: • Critical to NWS mission • Used by EM's, local govts, Mets and other professionals • Used by individuals to make important decisions • Very popular • During landfall hurricane, radar pages account for 40-50% of web traffic • Ex: 172,620,000 individual users in Sept 2004 • Account for 20-40% of traffic on “normal” days NWS SOUTHERN REGION www.srh.weather.gov

  6. RIDGE • Ridge • Based on software from North Texas Council of Goverments • User interface changes based on ad-hoc user comments • Focus on GIS • First test started February 2004 • Early version was replaced in Spring 2005 with layered GIS approach. NWS SOUTHERN REGION www.srh.weather.gov

  7. Customer feedback • Comment period opened from May 23 to September 5, 2005 • Nearly 24,000 comments received • Many technical comments used to tweak the user interface, greatly improving the displays • Users overwhelming supported and enjoy the displays • 75 percent said they use the service once or more per day NWS SOUTHERN REGION www.srh.weather.gov

  8. Customer Feedback NWS SOUTHERN REGION www.srh.weather.gov

  9. Customer Feedback NWS SOUTHERN REGION www.srh.weather.gov

  10. RIDGE (What’s Involved) • Receipt and organization of files from NOAA Port • Decoding radar products • Exporting to transparent GIF (with World File) • Web page design (toggles, loops and zooms, 508 compliant) • Background/overlays • Create polygon overlay (Transparent GIF) NWS SOUTHERN REGION www.srh.weather.gov

  11. How do you use the website? Step 2: Move your mouse to determine how far away you are from where you clicked Step 1: Distance and location of left mouse click from the radar NWS SOUTHERN REGION www.srh.weather.gov

  12. How do you use the website? Toggle on and off the various types of overlays. This methodology will allow us to add more references. Change the product without changing webpages: CR,SRM,V,OHP, and STP. NWS SOUTHERN REGION www.srh.weather.gov

  13. Why GIS? • Images can be quickly and easily ingested into a GIS system (desktop GIS, IMS, etc.) for multiple needs • Layers (overlays) can be added and/or changed easily • Layers can be updated/maintained by the local NWS offices Rita data from HGX used to create real-time impacts that were given to folks in charge of first responders Katrina radar data displaced to give Texas DEM a feel for the scope of what they may be facing NWS SOUTHERN REGION www.srh.weather.gov

  14. What does the future hold? • Products Live Now • CR, N0R, N0Z, SRM,V,OHP, and STP • Products that can be decoded but are awaiting resources • Base Reflectivity 1.50, 2.50, 3.50Base Velocity 1.50ETSRM 1.50, 2.50, 3.50VILLRM Low, Mid, HighTHP ET and VIL Coming Soon! National and Regional Composites NWS SOUTHERN REGION www.srh.weather.gov

  15. RIDGE Future • Will become operational January 2006 • Old radar hits will be redirected to RIDGE • Modifications made in phases to avoid daily changes • Conversion to php, additional products, etc. • Team will remain intact and project becomes a line item NWS SOUTHERN REGION www.srh.weather.gov
