This document summarizes a study examining historical land cover classification at Cedarburg Bog in Wisconsin. The study aims to classify land cover in 1941 and 2000 from aerial photographs in order to identify changes over time in response to climate, land use, and human activities. The methods involve georeferencing and digitizing the 1941 aerial photos, classifying land cover into categories like forest, agriculture, water, and wetland, and comparing the results to published land cover maps from 1992 and 2001 to analyze major areas of land use change surrounding the bog over the past 60 years.
