Automated Data Plotter

This application dynamically generates many types of graphs. These graphs are derived from processing of various data sources done by the IEM. Please feel free to use these generated graphics in whatever way you wish. Reset App. The IEM Explorer application offers a simplified frontend to some of these autoplots.

Plot Description:

This application generates a map showing the coverage of a given VTEC alert. The tricky part here is how time is handled for events whereby zones/counties can be added / removed from the alert. If you specific an exact time, you should get the proper extent of the alert at that time. If you do not specify the time, you should get the total inclusion of any zones/counties that were added to the alert.

This plot can be run in three special modes, those are:

  • Single Event: Plots for a given WFO and event id.
  • Same Phen/Sig over multiple WFOs: The given single event is expanded in space to cover any coincident events for the given single event.
  • Same Phen/Sig over multiple WFOs: In this case, the event id is used to expand the plot. This makes most sense for SVR + TOR watches along with Tropical Alerts as the same event id is used over multiple WFOs.

Based on a sampling of recent timings for this application, plot generation time has averaged 4 seconds. Hold on for the plot is generating now!
