Enhancing Emergency Management with KML for RFC Product Dissemination

This workshop explores the use of Keyhole Markup Language (KML) as an accessible tool for emergency management and the public. It aims to simplify geospatial information dissemination without the need for complex GIS software. By integrating NWS-specific data with common base layers, participants can perform quick visual analyses and interpretations. Potential applications include 24-hour precipitation data, flood outlooks, and real-time information sharing across various scales. The workshop also emphasizes user-friendly resources and dynamic data management.

Presentation Transcript

  1. Using Keyhole Markup Language (KML) to disseminate RFC products Tech Transfer Workshop 2007

  2. Purpose- “poor man’s quick briefing tool” • Enabling Emergency Management and the public to utilize geospatial information without the overhead of GIS software and staff. • Combines NWS specific geospatial information with common base layer data for quick, convenient visual analysis and interpretation in a common environment.

  3. Ridge radar already available…

  4. KMZ based on WFO level… How about a national or RFC scale? AHAPS forecast point status available…

  5. RFC scale application… full hydrologic view

  6. RFC scale application… custom control

  7. RFC scale application… real-time info with link

  8. RFC scale application… 3D-like terrain display

  9. RFC scale application… 24 hour precip (QPE & obs)

  10. Potential products for KML • Ridge radar… already available • Forecast point status (obs and fcst) demo • 24 hr precipitation (QPE and obs) demo • Other QPE (1hr, 6hr, storm total) • QPF (6hr, day 1-3, 4-5, 5day total, etc) • Flood Outlook Potential? • Any geospatial dataset generated by NWS?

  11. Helpful base layers to provide • Hydrologic boundaries • Forecast group, basins, etc.dfd • County Warning Areas (CWAs) • Dam information? • Detailed Streams and Tributaries • Any geospatial dataset beneficial for interpreting or analyzing NWS data?

  12. Data file structure/ mgmt • Kml file compressed as .kmz • Provided as “one-time” download • Static data set (client side) • Contains all base layer data sets • Contains dynamic data links to access NWS specific data sets • Dynamic data set (server side) • Uploaded automatically to server as data sets change

  13. Beta test files for use… • http://www.srh.noaa.gov/wgrfc/kml/

  14. A few KML resources… • User Forum • http://bbs.keyhole.com • Documentation and Tutorials • http://code.google.com/apis/kml/documentation/ • KML viewers • Google Earth • ArcExplorer • NASA Worldwind
