Geomorphometry 2025. The 8th conference of the international society for geomorphometry

This volume collects the Proceedings of Geomorphometry 2025, the 8th conference of the International Society for Geomorphometry (ISG)1. The conference continues a well-established series of geomorphometry meetings, started in 2009 (Zurich, CH), and followed by meetings in Redlands (2011, US), Nanjing (2013, CN), Poznań (2015, PL), Boulder (2018, US), Perugia/online (2020/21, IT), and Iași (2023, RO). Other geomorphometry appointments that are held at regular intervals are the annual EGU in Vienna. Geomorphometry, broadly defined as the quantitative description and analysis of landforms and related processes, has progressively evolved from a collection of numerical descriptors into a mature scientific framework that integrates theory, data, and software tools. The increasing availability of digital terrain data, advances in data collection technologies, including ground stations and remote sensing technologies, in parallel with the development of sophisticated numerical methods and conceptual approaches linking surface landforms to land surface processes, all contributed to the evolution of the field.
