Geomorphometry 2023 - DEMIX Workshop

Published: May 10, 2023 by ISG Council

DEMIX (DEM Intercomparison eXercise) is a CEOS / WGCV / TMSG initiative supported by ESA as part of the EDAP+ project and by USGS. The objective of DEMIX is to compare global DEMs, and in particular, those at 1” arcsecond such as SRTM, ASTER GDEM, ALOS World-3D, NASADEM, COP-DEM, and FABDEM to allow different users to select the one that best suits their needs in their areas of interest. This choice is based on the results of criteria tested in different areas and evaluated using a “Wine contest” method where both quantitative and qualitative results can be freely combined for the candidate DEMs. The DEMIX project, developed out of a JRC workshop on Global DEM Benchmarking in 2019, started in July 2020 and is rolled out in three subgroups: (1) terminology and analytical basis, (2) algorithms and software, and (3) platforms and processing.

This DEMIX workshop is intended to present the results of this project, invite you to participate, and offer you access to the platforms and services that have been developed.

This workshop is co-organized by ISG:

and the CEOS Terrain Mapping Sub-Group:

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.

Get designing!

The editors,
Hannes Reuter

Coffee Talk - Recent Research Progress in Geomorphometry in China

Recent Research Progress in Geomorphometry in China

Dr. Li-Yang Xiong
Nanjing Normal University, 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)

Recording available in our YouTube channel

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.
