Iowa State GIS Day

On 20 Nov 2002, the IEM was privileged to be invitied as the keynote speaker for the Iowa State GIS Day. This page provides a link to the presentation and URLS for applications referenced in the talk.

>Example 1. Precipitation Analysis (discontinued)
Web mapping application that combines NEXRAD precipitation estimates with observations in near real-time.

Example 2 Iowa Tornado Database
Based on an Iowa Tornado reports archive, this web application allows you the ability to dynamically plot and query tornado reports.

Example 3 NWS Archive Warnings with National Composite NEXRAD
NWS severe bulletins are ingested into the IEM spatial database in real-time and combined with a recent national RADAR mosiac.

Example 4 3-4 June 2002 Flooding (discontinued)
This application was quickly produced last summer in response to flooding in Eastern Iowa on the dates of 3-4 June 2002.

Example 5 Dynamic Variable Plotting
With the IEM Currents page, you can dynamically select stations you would like to plot and the variable of your choice. The link may take you to a blank page, if so, you will want to select a data network and add stations to your favorites list.

Example 6 Archived NEXRAD vs ASOS/AWOS precipitation comparisons
This application allows dynamic comparisons between historical hourly rainfall estimates from the NEXRAD and observations from the AWOS/ASOS. Eventually, this application will work in real-time and archived mode and with other networks.

Example 7 IEM Site Location Maps
This slick application combines topography, photography and other layers with an IEM site location to produce a zoomable plot of a site's location. The maps are fascinating to look at. Once you follow the link, you will want to select a station and then "Location Maps".
