OpenStreetMap has become a key global source for outdoor mapping, and Mapy.com is one of the projects that builds on it, providing detailed hiking and cycling maps for millions of users.\n\nThis session will show, through concrete examples from Mapy.com, how OSM data is applied to outdoor navigation\u2014covering trails, cycle routes, elevation details, and outdoor-specific points of interest such as shelters, springs, and viewpoints. We will discuss what works well in OSM today and highlight best practices for outdoor tagging.\n\nAt the same time, we will address challenges: countries or regions where data coverage is incomplete, inconsistent tagging across borders, and missing details that limit outdoor usability. These examples will illustrate how contributors and communities can focus efforts to close gaps and improve OSM for outdoor purposes.\n\nParticipants will leave with practical insights into how OSM can be used effectively for outdoor activities, and how projects like Mapy.com demonstrate its potential when combined with community contributions.", "recording_license": "", "do_not_record": false, "persons": [{"code": "LFHKY8", "name": "Jakub Zmrzlik", "avatar": "https://pretalx.com/media/avatars/LFHKY8_BAgLnKE.webp", "biography": null, "public_name": "Jakub Zmrzlik", "guid": "83474efc-4aa4-5b0f-b6e5-b3638ffb16a6", "url": "https://pretalx.com/sotmeu2025/speaker/LFHKY8/"}], "links": [], "feedback_url": "https://pretalx.com/sotmeu2025/talk/XHM78K/feedback/", "origin_url": "https://pretalx.com/sotmeu2025/talk/XHM78K/", "attachments": []}, {"guid": "51465d81-f7fb-5952-89a4-11d5acae37bc", "code": "SDH7HG", "id": 81585, "logo": null, "date": "2025-11-14T17:00:00+00:00", "start": "17:00", "end": "2025-11-14T17:30:00+00:00", "duration": "00:30", "room": "Area", "slug": "sotmeu2025-81585-lightning-talks-1", "url": "https://pretalx.com/sotmeu2025/talk/SDH7HG/", "title": "Lightning Talks 1", "subtitle": "", "track": "Special sessions", "type": "Other", "language": "en", "abstract": "5 slots for quick 5-minute talks.

As President of KU YouthMappers and a Geomatics Engineering student, I\u2019ve led a youth-driven initiative that blends technical precision with emotional outreach\u2014empowering communities through open data and WhatsApp-friendly mapping guides.\nThis talk shares our journey: how student-led mapathons, tribute cartography, and interdisciplinary collaboration have helped visualize flood zones, glacial lake threats, and vulnerable settlements. At the heart of our work is a commitment to women-led geospatial advocacy, where female mappers lead workshops, design resources, and inspire others to map with purpose.\nBy linking Nepal\u2019s grassroots innovation with Europe\u2019s open mapping ecosystem, this presentation invites a conversation on how cartography can be both scalable and soulful. Whether in the highlands of Scotland or the hills of Sindhupalchok, the mission is shared: to map not just terrain, but resilience, memory, and hope.\nLet\u2019s reimagine mapping as a language of empowerment\u2014spoken in pixels, poetry, and the quiet determination of those who dare to chart a better future.", "recording_license": "", "do_not_record": false, "persons": [{"code": "3UNRQL", "name": "Prativa Thapa", "avatar": "https://pretalx.com/media/avatars/3UNRQL_ePCezAA.webp", "biography": "Prativa Thapa, a third-year Geomatics Engineering student at Kathmandu University, is the Executive Member of GES, Sole Mapping Lead for 2025 and President of KU YouthMappers.
