Recent technical developments have enabled us to acquire high-definition topographic and geophysical data for geoscientific research, including land surface processes, subsurface structures, submarine/aerial environments, and geo-ecological interactions. Such high-definition or high-resolution data of the Earth's surface, hereby referred to as HiMESD (High-definition Multilayered Earth Surface Data), are particularly useful for studies on landscape developments over relatively short-term (decadal to millennial time scales), which are often assessed with the concept of connectivity in spatial and temporal contexts. HiMESD from ground and airborne platforms has become ubiquitous in everyday life, from car navigation systems to automated vacuum cleaners at home, playing a central role in quantifying and understanding "connectivity" in transportation networks, as well as in the sediment cascade from steep mountain tops to shallow and slow coastal rivers. HiMESD takes center stage, from the "micro-scale" of robot navigation to identifying the connectivity of active and more quiescent fault lines spanning several tens of kilometers.
In this session, we invite submissions on topics that challenge the issues of connectivity in the Anthropocene, the most recent geological era of the Earth affected by human activities. A range of topics would fit the session framework, including theoretical work, data acquisition, pre- and post-processing, extensive data preservation and archiving, statistical analysis, physical modeling, machine learning, and numerical simulation. The methodological approaches may include, but are not limited to, laser scanning (Lidar), photogrammetry (SfM), GNSS precise positioning, SAR interferometry, multi-beam sonar, ground-penetrating radar, geomagnetic/electromagnetic sensors, and multi/hyperspectral sensors, based on terrestrial (fixed or mobile), aerial (UAS/UAV or manned airborne), or satellite platforms.
