GIS Data
What is GIS?
GIS (Geographic Information Systems) is a system that captures, stores, analyzes, manages and presents data that
is geographically referenced. ArcView and Google Earth are two of the most common programs that display geographically referenced data.

The form of data that will be provided on this page will comprise mainly of KMZ files (Google Earth) and shapefiles (ArcView and other software).



The following files (containing tornado tracks) are for use with GIS software. The KMZ (compressed KML) files are intended for applications such as Google Earth or ArcGIS Explorer. Right click on the link(s) of your choice and "Save Link As" or "Save Target As" to your computer. View using the appropriate application(s). When opening KMZ files in Google Earth, please note it will initially load in the temporary places folder.

For a description of each event (if there is one available), including damage on the HTML link provided. 

* When clicking on photos within Google Earth, please be patient as it may take a little time for them to load
