Using Ground-level Imagery to Map Landscape Change

Much of the research literature on landscape change has focused on aerial imagery or satellite imagery from remote sensing sources. This is understandable if one were to look at wide areas. However, ground-level photographs also have great value to demonstrate landscape change from a human eye-level perspective. Combing such ground-level photographs with fieldwork and spatial analysis provides the possibility to assess human-environmental factors that have led to sometimes drastic change in the landscape. Yellowstone has become one of the most popular national parks in the United States.
