Abstract:
This polyline shapefile represents the estimated paths of tornadoes in Wisconsin based on satellite imagery processed at the Environmental Remote Sensing Center, (ERSC) and WisconsinView at the University of Wisconsin-Madison.

The Environmental Remote Sensing Center began using satellite imagery to identify the location and extent of tornado damage in 2001 following the Siren Tornado of June 18, 2001. Before and after imagery can be compared statistically to produce "change" maps of damage. On August 18, 2005 nearly two dozen tornadoes ripped through southwest and south central Wisconsin. ERSC acquired imagery and identified the "swaths" or "paths" of three of the more destructive tornadoes. This shapefile represents the estimated paths of destruction of the Siren tornado and the three Aug 18, 2005 tornadoes. Other may follow as the analysis continues or as other events occur. This data layer is intended to help emergency management personnel, researchers and the general public to identify the location of tornado paths in their GIS applications.

Purpose:
The purpose of this file is to help county, state, and federal emergency management agencies in their response to events.
Supplemental_Information:
Three of the tornadoes represented in this shapefile are from the same day, August 18, 2005 and one is from a tornado that hit Siren, WI in 2001. Others may be added to this layer in future versions.

Attribute:
Attribute_Label: Est_Length
Attribute_Definition:
Length of damage track in meters interpreted from satellite photo analysis.
Attribute_Value_Accuracy_Information:
Attribute_Value_Accuracy: Approximate only. Very conservative estimate.
Attribute_Value_Accuracy_Explanation:
Damage visible from satellite imagery is limited to the resolution of the imagery. Generally 30m pixel resolution is available. Therefore, the estimated length is very approximate and only accounts for the most obvious damage as seen from the satellite.
Attribute:
Attribute_Label: Length_km
Attribute_Definition:
Kilometers calculated from Est_Length attribute by dividing by 1000.
Attribute:
Attribute_Label: Length_mi
Attribute_Definition: Miles calculated from Length_km by multiplying by 0.6214
