  • When / room: 2026-08-30 12:40 · Martinique · OSM Science · Academic Lightning Talk
  • Duration: 5:30
  • Summary: StreetMeasure estimates road dimensions from 360° street-level imagery (DA360 monocular depth, SAM 2 segmentation) plus satellite transects, targeting missing OSM width=* and lanes=* on highway features. The case study is the 16 km SP6 provincial road (Piacenza, Italy), with in-situ checks of estimated lane width. Results are meant to update OSM width and lanes tags and support a provincial digital road cadaster / digital-twin workflow.
  • Tags: streetmeasure, width, lanes, street-level-imagery, monocular-depth, piacenza, osm-science
  • Highlight topics: lanes — explicitly targets missing lanes=* (and width=*) and measuring the width of each lane on SP6; quality evaluation — compares estimated lane width with ground-truth measurements

  • Speakers: Camille Bernard, PedroPinheiro
  • When / room: 2026-08-30 10:05 · Martinique · OSM Science · Academic Talk
  • Duration: 31:36
  • Summary: The paper extracts full OSM edit histories (planet history via ohsome-planet) for Lisbon, Grenoble, and Paris and classifies version-to-version transitions (existence, category, attributes, geometry, structure). The method is instantiated on cycling-infrastructure tags—dedicated cycleways, shared-use paths, on-road cycleway=lane, and designated routes—to study documentation of a shift toward soft mobility. A further interpretative layer aims to separate real-world infrastructure change from refinements, error corrections, and ambiguous edits; a web application explores those change dynamics.
  • Tags: change-detection, ohsome, cycling-infrastructure, cycleways, semantic-annotation, osm-science
  • Highlight topics: monitoring of changes — core work is detecting, classifying, and semantically interpreting OSM edits over time; bikelanes — tracked classes include dedicated cycleways and on-road lanes tagged cycleway=lane; verkehrswende — stated aim includes whether cities are transitioning toward soft mobility as seen in cycling infrastructure in OSM; quality evaluation — distinguishes genuine ground change from tagging corrections and modeling decisions

  • Speakers: Pierre-Leo Bourbonnais, Yannick Brosseau
  • When / room: 2026-08-30 12:25 · Martinique · OSM Science · Academic Lightning Talk
  • Duration: 6:48
  • Summary: The study measures how using OSM entrance=* instead of building or parcel centroids changes accessibility-style distances to the road network and transit stops, on a global population- and built-volume-weighted sample. The public text argues centroid proxies can misrepresent pedestrian access, wheelchair routing, first-/last-mile transit, and curbside drop-off on large multi-building sites. A Rust/React/MapLibre review tool records those measurements and offers deeplinks to the iD editor; a preliminary sample of about 25 POIs finds longer walks from centroids than from the nearest tagged entrance in 24 of 25 cases.
  • Tags: poi, entrance, accessibility, pedestrian-access, routing, maplibre, id-editor, osm-science
  • Highlight topics: routing — quantifies effects on walking and transit access and cites wheelchair routing and routing engines as use cases; maplibre — review service is described as a Rust/React/MapLibre application; iD-editor — POI focus screen provides deeplinks to the OSM iD editor

  • Duration: 23:12
  • Summary: Samuel Deschamps-Berger describes the Base Nationale des Aménagements Cyclables (BNAC), a French national cycling-infrastructure dataset that emerged after the Loi d’Orientation des Mobilités. Geovelo, Carto’Cité, government and local authorities, and the OSM community chose OSM as the flexible core rather than a closed silo. The talk covers transforming OSM tags into a national schema, a feedback loop for authorities to contribute back to OSM, and a reported result of over 110,000 km of cycling paths harmonized and published.
  • Tags: bnac, cycling-infrastructure, france, geovelo, lom, national-standard, user-experiences

  • Duration: 20:28
  • Summary: Jakub Zmrzlik reports production lessons from Mapy.com, a hiking- and cycling-oriented map app used by millions and built largely on OSM. The public text stresses incomplete or inconsistent route networks, regional quality differences, and attributes such as surface, difficulty, access, and seasonal limits—problems that can yield routes that look valid on the map but fail outdoors. The talk also covers routing over fragmented trails, cartographic heuristics, overtourism/constraints, and feeding issues back to the OSM community.
  • Tags: mapy-com, outdoor-navigation, hiking, cycling, routing, data-quality, cartography
  • Highlight topics: routing — production outdoor navigation and routing across incomplete hiking and cycling networks; quality evaluation — describes completeness, consistency, and tagging quality problems that affect real-world navigation

  • Duration: 29:26
  • Summary: OSM Skeleton is a step-by-step method to find missing, inaccurate, incomplete, or obsolete “backbone” features (settlement nodes, main connecting roads, residential extent) using external data, spatial analysis, and metrics, including a hybrid residential/street-network feature. Issues are national-scale OGC (WMS/WFS) layers via PostgreSQL/geOrchestra, with click-through mapping instructions and open-in-JOSM or iD. The talk also covers POI completeness scores for towns, daily statistics by issue and admin division, origins in Africa and South America, and a preference for local (not remote) mapping. It notes Osmose, MapRoulette, and OSMCha as existing validators that have not resolved heterogeneity; ohsome dashboard and HOT osm-analytics are described as seeming discontinued.
  • Tags: data-completeness, heterogeneity, backbone, ogc, josm, id-editor, poi-completeness, georchestra

  • Summary: The French Outdoors group (hikers and mountain bikers since 2021, now also professionals and institutions) reports successes: ~30,000 km of node networks, hiking-route continuity above 90% on ~200,000 km (~95% continuous vs earlier sketchy maps), QA via Knooppuntnet and Waymarkedtrails, cartes.app outdoors style, and some operator collaborations. Challenges include getting ~3,000 route operators to maintain their own routes, OSM tagging vs loop-network designs that trip QA, one–two routes broken daily (relation integrity in JOSM and iD), land-owner deletions, and mountain incidents involving OSM-based maps. They want a BOF on tagging/modelling with other countries.

Phase one measures intrinsic quality: tag completeness for surface, lighting, width, and maxspeed; tagging consistency; and NetworkX topological connectivity per hierarchy. Phase two, only where tags allow, compares infrastructure to UNECE (2025) and EuroVelo certification criteria (width by hierarchy, surface tiers, speed vs physical separation). Bicycle relations are treated as the backbone linking way-level attributes to network-level meaning.

Shortest-path routing plus locally calibrated speeds from GPS and remote sensing estimated household travel times to facilities; many people live more than one hour away (some 4–5 hours). Distance-decay of community-health use (~28% fewer consultations per extra km) informed CHW siting, and VRPTW routing planned door-to-door CHW itineraries. Nationwide household-level mapping is estimated at 220–350 person-years (~USD 1 million).

European extracts show uneven explicit maxspeed coverage (e.g. NL 68%, DE 33%, FR 21% of car-drivable ways). A single-file spatial SQLite (RTree) beat other packaging on latency/update trade-off; Germany daily diffs were measured for update cost. GPS replay (42,654 fixes) reached 94% matching accuracy at 8.5 ms p95; Valhalla matched similarly but used more space and was not automatically better under mobile constraints. Observed issues can be exported as .osc for human OSM edits, not auto-upload.

  • Duration: 5:00
  • Summary: The study estimates how much publicly accessible indoor space in European cities is relevant to map, to judge indoor completeness and infrastructure impact. Candidate buildings are classed from tags and amenities; publicly accessible share is estimated from Neufert design guidelines. Test cities are Pécs, Dresden, Budapest, and Berlin. A preliminary Dresden figure: ~13.2 km² indoor area in buildings with some public space, 5.13 km² estimated publicly accessible, 0.085 km² currently mapped. Motivation includes maps and routers extending into indoor walkable areas, corridors, and stairs.

  • Duration: 5:04
  • Summary: The study tests whether OSM-derived variables can explain 85th-percentile urban operating speed (V85) in Curitiba, Brazil, using naturalistic driving data (NDS-BR), IBGE socioeconomics, and a 200×200 m grid. Predictors included road-network length/density, bus stops, intersections, traffic signals, and speed cameras; OLS had low explanatory power (R² ≈ 0.10), while a Spatial Lag Model fit better but still left large errors (RMSE ≈ 14.8). Network density and traffic signals associated negatively with V85; bus stops and speed cameras were not significant. The authors conclude OSM is more suitable for exploratory large-scale safety analysis than precise prediction, citing missing attributes such as lane width, geometry, traffic volume, and detailed functional classification.

  • Duration: 4:34
  • Summary: Introduces PTSA, which groups public-transport objects into stop-level units from geometry and tags in order to visualize mapping habits (PTv1 vs PTv2) and flag inconsistent or possibly erroneous data for mappers. The technical focus is measuring many 1–500 m distances efficiently with guaranteed accuracy: subdivide landmass by administrative boundaries, compute smallest enclosing circles on the sphere, and use Euclidean distances on azimuthal equidistant projections. A new (hemi-)spherical Welzl algorithm (linear time; PyPI) supplies those circles; source and planet subdivisions are published.

  • Duration: 5:44
  • Summary: Beyond using OSM for street/path networks and travel times, the paper derives destination attractiveness (expected daily trip ends) for traffic analysis zones from OSM POIs, building/floor area, and published trip-attraction rates (e.g. VerBau in Germany). The Python/R workflow is published as OSM2Attractiveness and was applied in Hamburg, Karlsruhe, and Stuttgart with the agent-based model mobiTopp. Completeness varies by activity type; shopping is often more robust than private business/services; OSM can be more complete than official sources for some types. Limits include missing floor counts and mixed uses; authors recommend complementary building models and brand size defaults.

Edits are owner-triggered, first-party, opt-in, with safeguards (no deletes/geometry/primary-tag overwrite, no auto-create by default, optimistic concurrency). Forum threads changed the publisher: prefer contact:* over addr:*, reclassify social URLs, add ref:FR:SIRET, use disused: for closures, validate websites. A 2-hour sync detects external OSM changes but does not auto-revert. Principle: “fix the process, not the POI.”

  • Summary: A reproducible Python/OSMnx workflow detects informal settlements from OSM building footprints using urban-morphology metrics and Delaunay topology. Training is Korail (Dhaka); transfer tests are Katanga (Kampala) and Ricardo Brugada (Asunción). A stepwise threshold search generalised better than a Random Forest that overfit; topology metrics added little to classification. Results argue informal settlements do not share one universal morphological signature, limiting model transfer. The work is framed around SDG 11 and data-scarce Global South contexts.

  • Summary: OSM for Cities is a web platform for searching a city, browsing 200+ dataset categories, and downloading GeoJSON filtered by administrative boundaries, aimed at non-GIS users. The talk frames this against earlier Mexico City bus-network GPS work that died in proprietary reports, and argues city-level OSM extraction is still hard for planners. Categories named include schools, healthcare, cycling infrastructure, and transit; the stack includes a self-hosted Overpass instance. The open-source project invites planners, researchers, mappers, and officials to use it and share use cases.

OSM is the geodatabase for Rennes, Rybnik, Turin, and Stockholm, extracting leisure=park and landuse=recreation_ground with a name filter. Thirty-one indicators use automatic OSM extraction, a qualitative form, or mixed sources; a GoGoCarto UI maps results and syncs with OSM. The prototype is to be tested by partner cities by September 2026.

  • Summary: The study estimates how much publicly accessible indoor space in European cities is relevant to map, to judge indoor completeness and infrastructure impact. Candidate buildings are classed from tags and amenities; publicly accessible share is estimated from Neufert design guidelines. Test cities are Pécs, Dresden, Budapest, and Berlin. A preliminary Dresden figure: ~13.2 km² indoor area in buildings with some public space, 5.13 km² estimated publicly accessible, 0.085 km² currently mapped. Motivation includes maps and routers extending into indoor walkable areas, corridors, and stairs.

Earlier mid-2010s critiques of digital humanitarianism are treated as partly “metabolized” in the TM. Humanitarian mapping is framed as oscillating between empowerment and technocratic rationality amid data inequalities.

The Python/R workflow is published as OSM2Attractiveness and was applied in Hamburg, Karlsruhe, and Stuttgart with the agent-based model mobiTopp. Completeness varies by activity type; shopping is often more robust than private business/services; OSM can be more complete than official sources for some types. Limits include missing floor counts and mixed uses; authors recommend complementary building models and brand size defaults.

  • Summary: The study tests whether OSM-derived variables can explain 85th-percentile urban operating speed (V85) in Curitiba, Brazil, using naturalistic driving data (NDS-BR), IBGE socioeconomics, and a 200×200 m grid. Predictors included road-network length/density, bus stops, intersections, traffic signals, and speed cameras; OLS had low explanatory power (R² ≈ 0.10), while a Spatial Lag Model fit better but still left large errors (RMSE ≈ 14.8). Network density and traffic signals associated negatively with V85; bus stops and speed cameras were not significant. The authors conclude OSM is more suitable for exploratory large-scale safety analysis than precise prediction, citing missing attributes such as lane width, geometry, traffic volume, and detailed functional classification.

  • Summary: Samuel Deschamps-Berger describes the Base Nationale des Aménagements Cyclables (BNAC), a French national cycling-infrastructure dataset that emerged after the Loi d’Orientation des Mobilités. Geovelo, Carto’Cité, government and local authorities, and the OSM community chose OSM as the flexible core rather than a closed silo. The talk covers transforming OSM tags into a national schema, a feedback loop for authorities to contribute back to OSM, and a reported result of over 110,000 km of cycling paths harmonized and published.

  • Duration: 29:36
  • Summary: The talk evaluates corporate editing (Meta, Grab, and Kaart changeset hashtags) in five Southeast Asian countries, 2015–2025, using a composite “collective intelligence” score from completeness, tag richness, building geometry complexity, diversity, innovation, and evenness on highway=* and building=* (OHSOME). For Thailand and Malaysia, corporate editing often raises innovation and completeness, some waves reduce decentralization, and effects are described as fading within about two years. The Philippines, with little corporate involvement, scores highest on the composite.

  • When / room: 2026-08-30 10:05 · Martinique · OSM Science · Academic Talk
  • Duration: 31:36
  • Summary: The paper extracts full OSM edit histories (planet history via ohsome-planet) for Lisbon, Grenoble, and Paris and classifies version-to-version transitions (existence, category, attributes, geometry, structure). The method is instantiated on cycling-infrastructure tags—dedicated cycleways, shared-use paths, on-road cycleway=lane, and designated routes—to study documentation of a shift toward soft mobility. A further interpretative layer aims to separate real-world infrastructure change from refinements, error corrections, and ambiguous edits; a web application explores those change dynamics.
  • Tags: change-detection, ohsome, cycling-infrastructure, cycleways, semantic-annotation, osm-science
  • Highlight topics: monitoring of changes — core work is detecting, classifying, and semantically interpreting OSM edits over time; bikelanes — tracked classes include dedicated cycleways and on-road lanes tagged cycleway=lane; verkehrswende — stated aim includes whether cities are transitioning toward soft mobility as seen in cycling infrastructure in OSM; quality evaluation — distinguishes genuine ground change from tagging corrections and modeling decisions

  • Duration: 25:48
  • Summary: The speaker proposes an intrinsic OSM completeness metric from the temporal evolution of mean added feature size for roads and buildings, using only aggregate Ohsome statistics and no external reference. The assumption is exploration then densification: average added length or area falls until a saturation threshold. On 446 regions the exploratory results label 17% complete for buildings and 8% for roads; the method is called robust but restrictive, with planned extrinsic checks against Overture and Survey of Israel buildings.

  • Summary: The speaker extracts OSM mining-related tags via Overpass and Taginfo, filters heritage, abandoned, tourist, and atypical geometries, and aggregates to 39,291 candidate mining-site points. That layer is compared with the global mining inventories of Maus et al. (2022) and Tang and Werner (2023). Spatial overlap is low (about 7–9% of OSM sites inside those polygons); OSM is described as relatively dense in Europe and underrepresented elsewhere, with discussion of completeness and tagging or geometry errors.

  • When / room: 2026-08-30 12:25 · Martinique · OSM Science · Academic Lightning Talk
  • Duration: 6:48
  • Summary: The study measures how using OSM entrance=* instead of building or parcel centroids changes accessibility-style distances to the road network and transit stops, on a global population- and built-volume-weighted sample. The public text argues centroid proxies can misrepresent pedestrian access, wheelchair routing, first-/last-mile transit, and curbside drop-off on large multi-building sites. A Rust/React/MapLibre review tool records those measurements and offers deeplinks to the iD editor; a preliminary sample of about 25 POIs finds longer walks from centroids than from the nearest tagged entrance in 24 of 25 cases.

It reports a sharp post-invasion spike in building edits around Kyiv, a moderate correlation with bombardment events, and mapping near the frontline including occupied areas. Deletions and ruin-related tags are discussed as possible proxies for physical destruction.
