Special issue  

This special issue aims to demonstrate the advantages of high-resolution topography (e.g. SfM-MVS and lidar methods) to measure and understand earth surface processes at multiple temporal and spatial scales. Rapid, flexible and straightforward data acquisition and processing without extensive expert knowledge enable capturing and monitoring of geomorphic processes at unprecedented scales. Thereby, the potential of novel process insights due to the achievable temporal scales at simultaneous high spatial resolution is of interest. The special issue invites submissions that fit within the scope of 4-D (space and time) topographic reconstruction to inform geomorphological process understanding, though manuscripts that also identify new applications and developments in data acquisition and post-processing are welcome
