Visualization of temporal changes in environmental point cloud scans

Gorup, Gorazd (author), Bohak, Ciril (author)

Expert analysis of environmental point clouds is often overwhelmed by the volume of raw data. This study introduces an integrated visualization approach to simplify the detection of temporal surface changes. By developing a prototype that identifies and displays rockfall and deposition areas, we bridge the gap between complex geomorphological data and intuitive visual feedback. In addition to expert tools, we present a method for generating animated cliff displays to communicate environmental risks to the general public. We evaluate the effectiveness of these visualizations and discuss the trade-offs of using the M3C2 algorithm for volumetric analysis, concluding that visual synthesis is an essential tool for modern geomorphological research.
