GRASS GIS v8 release end of 2021

Published: Oct 30, 2021 by ISG Board

The GRASS GIS development team has used the lock-down times also to work hard on the v8 release of the popular GRASS GIS software (see complete list of new functionality).

There are many new additions to the raster library expected and likely Digital Terrain Modeling and analysis should likely run smoother. The GRASS GIS will stay available via QGIS but also will provide direct Python 3 support and of course R community should be able to access GRASS modules directly via the rgrass package.

We are looking forward to seeing the new GRASS GIS in action!

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
Carlos Grohmann
Vincent Lecours

Coffee Talk - Recent Research Progress in Geomorphometry in China

Recent Research Progress in Geomorphometry in China

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.
