This inter-disciplinary session will bring together researchers working on geospatial data acquisition and processing and those analysing digital models (DEMs) of the Earth's land surface, seafloor, and planetary terrains. The session reaches from innovation in measurement technologies with state-of-the-art processing, novel quantitative analysis of DEMs, data fusion, and the resurgence in geomorphological mapping. Best practices will be exchanged, results discussed within a wide context, and new opportunities identified.
We intend insights into both natural processes and those creating a human fingerprint in the landscape. Features identified or parameterised could include volcanoes, craters, gullies, fault scarps, drumlins, or those reflecting anthropogenic disturbances such as land-use change. Natural processes constrained could range from mass-wasting to volcano formation, and from flooding to sedimentary deposition.
SUB-SESSIONS
1) High definition topography - data acquisition, modelling, interpretation
Advances in close-range surveying technology (photogrammetry/laser-scanning) allow geomorphologists and geoscientists to benefit from data at both higher spatial resolution and improved precision. This sub-session highlights these rapidly evolving and increasingly cost effective technologies. Sub-session supported by activities of ISPRS (Int. Soc. Photogrammetry and Remote Sensing) working group V5 (isprsv5.lboro.ac.uk)
2) Digital Landscapes: Quantitative Interrogation and Use to Examine Geomorphic Processes
Objective, robust and reproducible quantitative methods of analysis underpin our ability to bridge the gap between geomorphic form and its formational process. This sub-session will emphasize methodological developments that create exciting new observations and unlock the potential wealth of new insights into geomorphic processes recorded in DEMs.
3) Geomorphological maps - indispensible tools in geomorphology
Geomorphological maps have played an important role in various fields of geomorphology and the geosciences owing to their predictive power for e.g. soil and geohazard mapping purposes. This sub-session focusses on recent advances in generating, assessing, utilizing and disseminating geomorphological maps at different spatial scales and variable environments.
