RESEARCHERS TRACK LAKE CLARITY FROM SPACE
MADISON – Assisted by hundreds of volunteers around the
state, University of Wisconsin-Madison researchers and their cooperators have
developed a method
of assessing the water quality of Wisconsin's lakes from space.
Using images captured 438 miles above the earth, they have completed the first
satellite-based inventory of the clarity of the largest 8,000 lakes in the state.
The inventory is available to the public in map form on the Web, where it is
possible to zoom in for a close look at your favorite lake or group of lakes...
|Landsat Image Gallery - Lake Images from Space
Satellite imagery provides researchers with valuable tools for assessing
a wide range of natural resource issues. This image gallery provides examples
of images used by scientists at the University of Wisconsin-Madison to assess
lake water clarity.
An additional gallery focuses on the southern portion of Lake Winnebago at Fond du Lac.

Lake Water Clarity: Measured by Satellite
Wisconsin has nearly 15,000 lakes. This 36" x
48" map shows the
estimated clarity, or transparency of the 8,000 largest of those lakes
as measured by satellite remote sensing. It is the first ever complete
of water clarity for the State of Wisconsin with such detail. Click here
