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.
Historical ground-based imagery plays an important role in helping us to reconstruct our past environment. This, along with combinations of modern remote sensing data and ground-based images, can also help us to quantify changes going on around us to demonstrate effects of climate change or land use change. Popular techniques such as structure-from-motion or even tools such as GIMP can also us to combine historical and modern data to gain a clearer perspective of that change.
