Using Keyhole Markup Language Using Keyhole Markup Language (KML) to disseminate RFC products(KML) to disseminate RFC products
Purpose- Purpose- “poor man’s quick briefing tool”“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.
Ridge radar already available…
KMZ based on WFO level…How about a national or RFC scale?
AHAPS forecast point status available…
RFC scale application… full hydrologic view
RFC scale application… custom control
RFC scale application… real-time info with link
RFC scale application… 3D-like terrain display
RFC scale application… 24 hour precip (QPE & obs)
Potential products for KMLPotential 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?
Helpful base layers to provideHelpful 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?
Data file structure/ mgmtData 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
