As far as I am aware this was the first international conference devoted specifically to this area of research, and since it was also my first visit to China it was an exciting and unique experience for me. The participants ranged from leaders in the field discussing visions and challenges for the future to students grappling with the possibilities and exploring new directions. These papers are a selection of the many presentations at the conference and give some indication of the breadth of research on show at the meeting. Digital terrain analysis has moved beyond a research tool into routine application, such as determination of catchment areas and flow pathways in hydrological
