Applying Geospatial Conventions to NWS Products Using IRIS


Why do we want nws products in geospatial conventions
Why do we want NWS products in Geospatial conventions

  • Flexibility

  • Format that is readily usable

  • Easy integration with other GIS datasets and systems


Requirements
Requirements

  • Process all products

  • Process the products quickly

  • Push them into a common format

  • End format has to be available

  • Needs to support GIS standards


What has been done already
What has been done already

  • UGC

  • Added polygon to warning

  • Adding of VTEC string

  • Warnings output as shapefile

    • Limited amount of products

  • Work on CAP format

  • None of these are geospatial conventions except shapefile.


Typical nws products
Typical NWS products

  • UGC

    MTZ012-050-054-055-010445-

  • VTEC

    /O.EXT.KHUN.FA.W.0022.000000T0000Z-090927T0030Z/

  • Polygon

Decoding data problems
Decoding data problems

  • Not all products have

    • Segments

    • Polygons

    • VTEC or HVTEC

  • And they change

    • So a programmer has to keep on top of product changes, and installed locations need to update.


Fix for problem
Fix for problem

  • Assumptions about products:

    • Treated as segmented

    • Don't maintain information about specific products

      • Checked for VTEC, and HVTEC

      • Checked for polygon


Storage of data using hibernate spatial

Using spring
Using Spring

  • Flexibility using Spring Framework

    • Support for caching of lookup data

    • Threaded Task Executor

    • Easy configuration/re-configuration

    • Integrates well with Hibernate and Spatial Hibernate



Support for gis conventions

Output in other formats
Output in other formats

  • Data can be exported to other various formats

    • GML

    • Shapefile

    • WKT

    • GEO Json

    • WMS

    • WFS

    • KML


Nws products supported
NWS Products supported

  • All Warnings

  • All Watches

  • LSRs

  • UGC based products


Examples
Examples

  • Some examples of the database being used

    • Web

    • GIS application


Multi use
Multi-Use

  • Now that we have the data in a Common format

    • Can use it in multiple projects with little effort.

      • On the web

      • Research

      • Verification

      • ?

    • Already being used in

      • Ridge II

      • Central Region GIS system.


Future work
Future Work

  • Push data on to JMS

  • Decode more data atomically

  • Stand-up more GIS services
