An Open Source Framework for Routing and Event Management in University Campuses

5*S: Space, Surveyors & Students is a collaborative STEM outreach project lead by Maynooth University, in partnership with the Irish National Mapping Agency, Tailte Éireann, Technological University Dublin, Esri Ireland and the Society of Chartered Surveyors Ireland. Funded by Research Ireland and the European Space Education Research Office (Esero) Ireland, these groups have a shared interest to encourage student enrolment on 'geo' courses at university from under-represented groups and also to preempt a looming skills-gap. 5*S provides interactive and engaging educational content and training to teachers and students (12 to 18 years old) who are interested in learning more about satellites, spatial data and SDGs. Leveraging a combination of ArcGIS StoryMaps, a bespoke Augmented Reality app (SatelliteSkill5 - free to download on PlayStore and AppStore) and the National Geospatial Data platform, Geohive - students and teachers are provided with curriculum-focussed content that help teach how to harness the power of spatial data to solve a set of challenges. Framed around the United Nations Global Geospatial Information Management 14 Fundamental Geospatial Data Themes, each core piece of 5*S content topic is tailored to fit into a packed school curriculum and has been trialled in almost 20% of second level schools in Ireland. The learnings from this tailored content have been recorded and evaluated through a series of quantitative and qualitative respondent questionnaires and teacher focus groups/one-on-one interviews. The findings suggest cross curricular potential, value-add for schools and confirm the importance of this for encouraging data literacy and supporting teacher agency.

TorchGeo is a Python library bringing support for geospatial data to the PyTorch deep learning ecosystem. First released over four years ago, TorchGeo has always had strong support for 2D satellite image data. The upcoming TorchGeo 1.0 release will add complete time series support, including 1D through 4D data, requiring a complete rewrite of all GeoDatasets and GeoSamplers. This talk describes the 1.5 years of open source work required to enable full time series support and the backwards-incompatible changes coming to TorchGeo. It also demonstrates the power and simplicity of TorchGeo through a series of case studies: 1D) air pollution, 3D) change detection and land cover mapping, and 4D) weather forecasting and climate modeling. TorchGeo is open source and released under an MIT license, with over 140 built-in datasets, 130 foundation model weights, and 120 contributors from around the world.

The International Society for Photogrammetry and Remote Sensing Student Consortium (ISPRS SC) serves as the official representation of students and young professionals within ISPRS, connecting a global network of more than 900 active members from 64 countries as of November 2025. This paper presents a comprehensive overview of ISPRS SC activities during the 2022-2025 Board of Directors tenure, highlighting significant expansion in educational outreach and capacity building initiatives. Key achievements include facilitating 15 summer schools across seven countries, providing hands-on training in emerging geospatial technologies, and organizing more than 40 webinars through partnerships with 10 ISPRS Working Groups, demonstrating substantial growth from 2 webinars in 2022 to 24 in 2025. The consortium successfully launched 11 Student Chapters worldwide, establishing localized networks that promote inclusive access to geospatial education across diverse regions. Through quarterly publication of the SpeCtrum newsletter, maintenance of active social media presence across four platforms reaching over 10,000 followers, and organization of networking events at major ISPRS symposia, the consortium has strengthened its communication, networking and professional development opportunities. The paper also discusses operational challenges including funding constraints, geographic representation gaps, and Board capacity limitations, while outlining future initiatives including a mentorship program, virtual symposium, and comprehensive Congress 2026 activities. These efforts underscore ISPRS SC's evolving role in developing the next generation of geospatial professionals equipped to address global sustainability challenges.

The densification of GNSS Continuously Operating Reference Station (CORS) networks in mountainous regions is constrained by the high cost of geodetic-grade equipment. Low-cost (LC) multi-frequency GNSS receivers offer a viable alternative, yet their performance in challenging high-altitude Alpine environments remains largely unexplored. This study evaluates the rover-side positioning performance and tropospheric delay estimation capability of a newly installed LC permanent station at Prali (2200~m elevation), in the Alpine region of Piedmont, Italy. The station, based on a u-blox ZED-F9P receiver with a broadband LC antenna and a Raspberry Pi computer, was assessed using Virtual Reference Station (VRS) corrections from the SPIN3 professional CORS network. Six independent two-hour RTK sessions across a full diurnal cycle were processed using RTKLIB in forward-only kinematic mode to emulate real-time conditions. Results demonstrate that the LC station achieves centimetre-level horizontal precision (8--11~mm) with fix rates up to 97\% and time to first fix below 3~minutes under favourable conditions. A diurnal performance variability was observed and characterised across the six sessions. Zenith Tropospheric Delay estimation via CSRS-PPP with 92\% fixed ambiguities yielded physically consistent values (mean ZTD~=~1811~mm, ZWD~=~41~mm), consistent with dry winter conditions at altitude. These results confirm that LC GNSS stations can deliver reliable centimetre-level positioning and meaningful tropospheric products in demanding Alpine environments, supporting their deployment for CORS network densification in regions where geodetic-grade infrastructure is economically or logistically prohibitive.

Over the last few years immersive technologies have experienced rapid advancement providing several solutions in geospatial education such as improving student preparedness, enhancing student learning of theoretical concepts and practical procedures, and even supporting remote learning. However, several educators cannot utilize such immersive technologies because many of the

existing applications are not suitable for geospatial learning. Use of immersive technologies in education often necessitates specialized software and application development with the total investment (in terms of cost and time) becoming a barrier. This project is spearheaded by Working Group V/1 of ISPRS, and it is also supported by the Education and Capacity Building Initiative (ECBI) 2024 grant to provide sample experiences to educators. This project developed two immersive experiences relevant to geospatial education that can be used to enhance lab delivery and learning. The first experience uses a simplified GNSS receiver for

topographic mapping in virtual reality (VR). The second experience uses a tablet and an external GNSS receiver to visualize 3D objects in augmented reality (AR). To design these two applications the research team distributed a global questionnaire to professionals and educators. The questionnaire assisted in understanding the participant’s experience with immersive technologies, their attitude and beliefs towards these tools, and the potential benefits that immersive technologies can bring in education and industry. The results from the VR/AR implementation indicate that interactive environments can effectively support student preparation and reveal common misconceptions in topographic data collection, highlighting their value as both training and diagnostic tools in geospatial education.

The GeoRek project, funded by the DAAD within the German-Ukrainian University Network, aims to strengthen geospatial education in Ukraine through digitalization and international cooperation. Implemented by Jade University of Applied Sciences (Germany) together with Kyiv National University of Construction and Architecture (KNUCA), Dnipro University of Technology, and the University of Bamberg, the initiative develops innovative e-learning tools and micro-credential systems for geodetic reconstruction and high accuracy documentation.

A central element of the project is the VRscan3D - virtual laser scanner simulator — an educational platform that enables realistic training in terrestrial and mobile laser scanning without the expensive equipment. The system supports interactive learning, gamified exercises, and data export for advanced processing.

GeoRek further establishes micro-certificates in key subjects such as terrestrial laser scanning, photogrammetry, and 3D/BIM data processing, aligning with European standards (ECTS, EQF) to promote flexible and lifelong learning. The project’s applied component includes real-life case studies on the digital documentation for reconstruction of war-damaged buildings in Ukraine.

Overall, GeoRek exemplifies how modern digital education can strengthen academic resilience, support reconstruction, and deepen long-term German-Ukrainian cooperation in geospatial sciences.
