The authors provide a very interesting work with a high benefit for researchers performing automatic continuous surface change detection. The study is very innovative and contains a great merit for many geo-scientific investigations because it enables the measurement of geomorphic processes in near real time and with high spatial resolution. Furthermore, the realised automation allows for long-term monitoring at hyper-temporal resolution.
The authors put great effort in revising the paper. They corresponded to each remark of both reviewers in detail and thoughtfully. The necessary changes are made to the manuscript.
The paper provides an important resource for researchers working with multi-temporal topographic data.
