Description

In an effort to get a better understanding of long-term trends on the lake, the University of Minnesota, in cooperation with Region 3 of the U.S. Fish and Wildlife Service has created a series of digitized spatial databases to document the distribution of wild rice on Rice Lake from 1983 through 2004. Aerial photos from seven individual years in that time period – 1983, 1993, 1995, 1996, 1998, 2001 and 2004 – were digitized, orthorectified and used as a thematic reference to create a threeclass representation (wild rice, other vegetation, and open water) of lake vegetation in a geographic information system (GIS) for each of the years analyzed. To create a spatial analysis of the wild rice and ‘other vegetation’ distribution over the entire time period, data from all the years were combined to produce a composite map.
