Workshop: Back to reality - Reconciling geomorphometry and geomorphology in the field

Published: Aug 31, 2009 by ISG Board

Workshop moderator: Oliver Korup

Location: Sihlwald area, SW of Lake Zurich

Meeting point: Zurich Central Railway Station (“Zürich HB”) @ “Group Meeting Point” (indicated by a large red cube!). Meeting time is 9 AM. Please try to be punctual so that we can catch the 9.18 service to Sihlwald station (train no. S4). There is no need for registered participants to purchase a ticket, which is included in the conference fees.

Daily programme:

  • Full-day field-based workshop: Sihlwald area 30 min. from Zurich on train (participants bring their own field lunch; there are several nice BBQ spots, so think of packing the odd sizzler; also make sure to bring plenty of fluids as late summer can still be very warm)
  • Brief overview of the area: Quaternary geomorphology, historic land use, recent conservation strategies
  • Review of key morphometric parameters and scale/resolution effects
  • Presentation of high-resolution LIDAR data for the area
  • Group-based exercises to determine locally morphometric parameters
  • Comparison of field- and LIDAR-derived parameters
  • Final group discussion on the advantages, potentials, and limits of LIDAR-based geomorphometry

NECESSARY EQUIPMENT: outdoor wear (incl. sturdy footwear and raingear)

INTENDED AIMS AND SCOPE: • To test the applicability and reliability of LIDAR and other DEM-derived attributes by comparison with field-derived data; • To raise awareness among LIDAR users of the potential pitfalls and limitations that come with enhanced resolution DEMs; • To re-appreciate the meaning of terrain parameters and their applicability in geomorphic research.

This field trip is also intended as an icebreaker reception, so socialising is more than welcome. We would like to use this opportunity to bring “geomorphometrists” together to discuss in an informal manner pending issues of high-resolution DEMs and DTMs in an actual landscape rather than at the desktop. The Sihlwald is a pleasant and mainly forested area near Zurich that caters for nearly all levels of fitness and recreational demands. It also hosts a number of challenges for digital terrain analyses, which we will explore during some leisurely walks and group discussions. The underlying idea is not to simply reiterate known problems of LiDAR data, but to consider ways of improving their use in geomorphometry and related disciplines.

Cover Design Contest for the Upcoming Book on Geomorphometry

Dear geomorphometry community,

We are pleased to invite submissions for a cover design contest for the second edition of the Geomorphometry book, to be published in 2026.

The submissions will be gathered in a poll, and the entire community will be able to vote for their favorite design.

If your design is selected, you will receive the appropriate credits, but would need to provide the necessary permissions to use the image.

You can submit your design by email before October 17th. Please ensure that the image is of at least 300 dpi resolution.

Coffee Talk - Recent Research Progress in Geomorphometry in China

Recent Research Progress in Geomorphometry in China

October 1st , 2025
8:00 MDT (UTC -6), 10:00 EDT (UTC -4), 11:00 BRT (UTC - 3), 15:00 BST (UTC +1), 16:00 CEST (UTC +2), 17:00 EEST (UTC +3), 22:00 CST (UTC +8)

Bio: Dr. Li-Yang Xiong is a professor at the School of Geographical Science, Nanjing Normal University (NNU), China. He is currently responsible for managing NNU’s research in Digital Terrain Model and Digital Terrain Analysis. His main research interests include AI based terrain modelling, loess terrain feature characterization, landform evolution modeling, paleotopography reconstruction and geomorphological process mining. His recent work involves deep learning-based DEM reconstruction, geomorphology-oriented digital terrain analysis, and value-added digital terrain applications for geoscience. He also serves as Associate Editor for the journal Earth Surface Processes and Landforms and as an Editorial Board Member for International Journal of Geographical Information Science.

Abstract: In this talk, I will present some recent research achievements related to terrain modelling theory, terrain analysis method and terrain application in China. This terrain modeling theory focused on how we understand terrain knowledge and integrate it into AI methods for terrain reconstruction. In term of the terrain analysis method, the mathematical vector operation we believe should be highlighted in the research of Geomorphometry, which is suitable for multi-source data structure by considering the directional property of terrain parameters. Actually, this directional property should be made a full consideration for process- oriented geographical modeling and simulation. Lastly, I will show some terrain applications towards different typical geographical areas in China as well as global scale application.
