Lake TSI Mapping:

Introducing a new method of determining the health of your lake with real time imaging.  A.W. Research Laboratories, Inc. has developed a multispectral camera that measures the Trophic Status Index for the entire lake.

The camera's capabilities are similar to combing approximately 870 manually collected samples per acre and mapping the results to one image in a timely manner.

TSI Lake Mapping provides mapped TSI values (for approximately every 50 sq. ft.) that would historically be determined by measuring the secchi depth, total phosphorous concentrations, chlorophyll a concentration, and placing the resulting values into the Carlson Trophic Status Index algorithms.  For more information on the Carlson Trophic Status Index please click here.

Financially, the TSI Lake Mapping is an affordable method for receiving the TSI values for the entire lake.  Traditionally, TSI data is only collected at a few sites.  TSI Lake Mapping uses aerial photography to map the lake, therefore this information is extremely useful since it encompasses the complete lake.

The results are displayed as an image data matrix of the complete lake.   Your TSI report is delivered via our website, and includes three image types, visible, thermal, and TSI. 

The visible image is a normal image of the lake.

The thermal image is displays hot and cold areas; white areas indicate hot and black areas indicate cold.

The TSI image displays the trophic status of  of the lake.  The index range is displayed below.
