I am Dibikshya Shrestha, a recent graduate in Geomatics Engineering from Tribhuvan University. My interest in open data and open-source software began in 2021 during my first year at university. Since then, I have been an active contributor to OpenStreetMap (OSM), having made over 653,756 edits to date. My passion for open data stems from its transformative potential. When accessible and reliable data is made openly available, it becomes a powerful tool for informed decision-making, inclusive development, and amplifying marginalised voices. This interest took a personal turn when I learnt about the critical role open data played in the response to the 2015 Gorkha Earthquake in Nepal—my hometown. This emotional connection motivated me to contribute more actively to humanitarian mapping efforts, believing that every edit truly matters. In addition to my contributions to OSM, I am a core member of OSGeo Nepal. Since its inception, I have been actively involved in community development, social media engagement, and volunteer coordination. Our shared vision is to expand this movement nationally and promote the welfare of the geospatial community in Nepal. I also served as secretary of the YouthMappers chapter GESAN, where I led several impactful initiatives, including a "map design competition using OSM datasets" (in collaboration with the Open Mapping Hub—Asia Pacific and NGES), a workshop on "how to use open geospatial datasets" (in collaboration with OSGeo Nepal), QGIS Training, and OSM Hackfest 2024 (in collaboration with TomTom Global). I am also a member of the OSM Foundation. I was honoured to be selected as a YouthMappers Leadership Fellow in 2024, and currently I am serving as the Volunteer YouthMappers Ambassador for Nepal. With this commitment, I strive to promote open data by creating, managing, and making it accessible to all, with the goal of utilising it for greater public welfare.

I am a remote sensing specialist who focuses on the environmental challenges we face today, with a particular interest in the maritime. I started in Physical Geography at Durham (UK), before moving on to a Masters in Environmental Science at Cambridge (UK). Since finishing a PhD in glaciology (Lund, Sweden) I worked in commercial geospatial intelligence, before moving back into academia with a focus on the validation and application of remotely sensed data (land surface temperature) at King’s College London (KCL). These projects involved collaboration with ILRI, NASA-JPL and ESA, working in diverse environments from East Africa to China and across Europe. After KCL I continued work on land surface temperature at the UK's National Centre for Earth Observation (NCEO). Most recently I spent time working in the maritime domain before taking up the post of lecturer at the University of Auckland.

Tim has over 20 years geospatial experience in public and private enterprise, with the last few years leaning heavily into FOSS4G solutions.

Tisham is a Senior Engineer at CSIRO Space and Astronomy division. Previously he held similar roles in various government agencies, private sector companies and startups. He has been pushing pixels since 2004 when he got started using medical imaging devices in Singapore. Since then he has had the priviledge of working with various space agencies such as NASA, DLR, JAXA, CNES etc. and lived through the explosion of publicly available satellite imagery.

Tom Kralidis is with the Meteorological Service of Canada and longtime contributor to FOSS4G. He leads and contributes to numerous projects in the Geopython ecosystem. He is the 2024 recipient of the Sol Katz Award for Free and Open Source Software for Geospatial (FOSS4G), awarded annually by OSGeo to individuals who have demonstrated leadership in the FOSS4G community.

Tom is the co-chair of the OGC API - Records Standards Working Group, chair of the WMO Expert Team on Metadata, and serves on the OSGeo Board of Directors. He is the 2024 recipient of the Sol Katz award.

I’ve been building GIS solutions at the Geodetic Institute of Slovenia for over 15 years, working across the stack on everything from web mapping applications to data processing pipelines. My background is in biomedical engineering, but I found my way into geospatial tech through the field of automation — and I’ve been streamlining processes and visualizing data ever since.

Ujaval is the founder of Spatial Thoughts - a learning platform for modern geospatial technologies. Ujaval got his Masters in Geospatial Information Engineering from the University of Wisconsin-Madison. After joining Google Inc. in California, he moved to India in 2006. He was one of the early employees at Google India and part of the team that launched Google Maps for India. He worked on multiple Geo teams at Google and led the GIS team in India.

After 15 years of corporate experience, he left Google in 2020 to work on his startup - Spatial Thoughts - to create a learning platform to bridge the skill gap in the geospatial industry. His online academy has trained participants from over 100 countries. His learning materials on QGIS, Python, Earth Engine, and GDAL are cited as the top learning resources globally and are used by more than 1 million people every year.

Ujaval is a world-renowned training facilitator and is passionate about advancing the use of open-source technologies in teaching and research. He is an active QGIS community contributor and a QGIS.org certified training provider.

Vasile Craciunescu is a researcher with more than 24 years experience, working for the Romanian National Meteorological Administration and Terrasigna, being in charge with the scientific and operational activities related to GIS database design and implementation, deployment of standardized web services, spatial enabled web interfaces, ETL, EO data processing, project management. He received his diploma in cartography and physical geography in 2001. He has a good experience in working and leading national, EU and ESA research projects. In 2006 Vasile started geo-spatial.org (http://geo-spatial.org), a collaborative effort by and for the Romanian community to facilitate the sharing of geospatial knowledge and the discovery and publishing of free geographic datasets and maps. Since 2011 he is the Romanian delegate in the Copernicus User Forum at the European Commission and the technical representative of Meteo Romania at Open Geospatial Consortium. In August 2014 he was elected to the Open Source Geospatial Foundation board of directors. For the last 14 years he has been teaching FOSS4G-based techniques at the Faculty of Geography - University of Bucharest in the first Romanian ICA-OSGeo Lab. Vasile was the chair of the 2019 FOSS4G international conference. From February 2021 he is the Romanian delegate in the Destination Earth Coordination Group and recently was appointed as national expert in the EEA EIONET Copernicus Technical Group.
