PFG 2024/6, the last issue in 2024, is out! It contains two papers as follow-up from the Virtual Geoscience Conference: on virtual field trip analysis, and a photogrammetric method for glacier monitoring. In addition, this issue features 5 original papers: on BBA for hyperspectral pushbroom scanner data, local evaluation of global models for road and building extraction, land surface temperature analysis, mixed reality for visualising underground facilities and an overview of digital twin research in city scope. In the report part some interesting reviews of conferences are given, but also links to online material from Wolfgang Förstner. Though the description in the report is in German, the material on geometric animations is in english: https://lnkd.in/eUQrqh65 Link to the issue: https://lnkd.in/e99tKubc

Building and road datasets are crucial built features and core elements of urban morphology. Their extraction has attracted significant research attention, leading to the generation of various open global datasets. However, beyond simple shape representation, these datasets can be leveraged to generate more annotations, such as extracting information on building quality, which can provide insights into the level of wealth. This necessitates a thorough understanding of the local accuracy of large-scale open datasets. Additionally, it is critical to explore different training and deployment strategies to generate such large-scale datasets while preserving local accuracy. This serves as a motivation for the Article here: Local Evaluation of Large-scale Remote Sensing Machine Learning-generated Building and Road Dataset https://lnkd.in/es3QHa_Y

Pleased to have our paper titled “Quantifying Virtual Field Trip Efficiency” published online today. In the paper we present a quantitative assessment of time, cost, logistical efficiency, carbon emissions, and achievement of learning outcomes for a virtual field trip to Utah, comparing the data directly to its physical field trip counterpart. https://lnkd.in/e4SmfexT John Howell, Adrian Hartley, Simon Buckley, Magda Chmielewska, Nicole Naumann, Prof. Nick Schofield, Rachel Brackenridge

One of the few positive things that came out of the Covid lock downs was the opportunity to run virtual fieldtrips and compare them to their physical equivalents. In a previous paper we compared the learning outcomes from the virtual and the real world trips. In our latest paper we ask the question are virtual fieldtrips are "more efficient" and if so how much more? - Spoiler Alert - they are! We also ask is efficiency the only thing that matters? - Spoiler alert - probably not. See the previous paper here https://lnkd.in/eqJBKdm9

The article I wish I had written!... So relevant. To finally put an end to the multitude of publications that consistently present misleading variations of the Gutenberg-Richter b-value. When will they realize that they are merely seeing computational biases?https://lnkd.in/etynJKH9

The article titled "Integrative Probabilistic Design of River Jetties by 3D Numerical Models of Transport Phenomena: The Case Study of Kabakoz River Jetties" that we wrote together with Can Elmar Balas was published in the Marine Science and Technology Bulletin.

Shear Force in RC Internal Beam-Column Connections for a Beam Loaded With a Transverse Force Occupying Different Possible Positions Abstract Frame structures are vulnerable to seismic impacts. The frame joint is the element that is often responsible for compromising frame structures. In recent years, shear force in the beam-column connection has been pointed out as the main culprit for damage in the nodes, and from there to the entire structure. The complex nature of the stressed and strained state of the joint is due to the poor knowledge of the forces passing in the beam-beam or column-column direction. For their more accurate determination, one departs from ...

Modelling the evolution of nearshore coastal processes always poses a challenge due to the complex interactions between waves, hydrodynamics and the coastal bed, especially in the presence of coastal protection works. Our publication (Modelling MDPI) presents an integrated numerical model, driven initially by a mild-slope wave model for the efficient simulation of nearshore coastal processes. The model is validated against experimental measurements, exhibiting solid performance in various settings, with special attention given to the wave structure interaction and the effect of wave reflection in longshore dynamics. If you're interested in the details, you can access our paper through the link: https://lnkd.in/de-ZaG_w. If you have any questions or would like to discuss the findings further, please feel free to reach out. Grateful for the collaboration with Assistant Professor Michalis Chondros and Dr. Andreas Papadimitriou.
