These lakes and wetlands are vulnerable to climate change, especially in ourstudy area of South Dakota, in which a period of deluge following a sharp droughtconsiderably expanded the areal extent of prairie pothole lakes during the last decade ofthe twentieth century. Preliminary estimates of lake areas, determined using Landsat 5and 7 images, had appreciable errors especially for the smallest of these lakes. Wedeveloped a new sub-pixel approach integrated with a Classification and Regression Tree(CART) model using a Geographical Information System (GIS) to quantify mixed waterpixels along lake boundaries to improve the area estimations for pothole lakes. Errors inestimated area were typically 10 percent or less for lakes greater than 1 hectare in size. 2008-09-12 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1220021657 http://rave.ohiolink.edu/etdc/view?acc_num=osu1220021657 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
