Historical terrestrial oblique images are a unique and invaluable resource for quantifying early changes of the alpine environment after the Little Ice Age. Becoming available in the second half of the 19th century, these images are the only visual sources documenting our environment in its nearly unaltered state. Hence, historical terrestrial images pose an incredible potential for many research areas including botany, hydrology, glaciology and geomorphology. Despite their unprecedented potential, historical terrestrial images are seldom used. The processing is time consuming, requires basic knowledge in photogrammetry and available tools are often difficult to use. Hence, researchers often fear investing time considering the uncertain outcome. In this short course, participants will learn the basics of photogrammetry necessary to understand the underlying concepts. This will enable them to assess the potential and limitations of historical terrestrial images for their respective research prior to the processing. Together with the participants we will evaluate and explore freely available tools discussing their pros and cons, focusing on the processing of selected historical images. After the short course, participants will be able to decide on their own if historical terrestrial images can be a valuable asset for their research, knowing their potential and limitations. Further, they will be able to use the available tools to incorporate historical terrestrial images into their respective research.
