The OpenStreetMap provides probably the most comprehensive digital path network for pedestrians, which had been largely unused in its actual depth of detail so far. Based on findings from the TERRAIN project, this talk will go into detail how this network can be used for roadside-aware pedestrian navigation efficiently, and what challenges and mappings problems occurred. Furthermore, specific need...

As of today we have OpenStreetMap but it doesn't fit all data and some data is not recommended for submission. We've got user reviews request in OsmAnd and Maps. Me and we would like to collaborate with OpenStreetMap community to create independent open platform for reviews. I would like to talk about how data could be stored and moderated and would like to explain how that data will be further in...

In early 2019, Open Data Manchester teamed up with Stockport council, Disability Stockport and Age UK Stockport to crowdsource data around mobility and accessibility in the town centre. This talk will cover the mapping methodology, findings, difficulties and solutions, as well as suggesting ways in which we can better map for these communities, making the data collected for OSM more inclusive and...

OpenMapTiles is an open-source set of tools for processing OpenStreetMap data into vector maps, which can be produced in various coordinate systems. OpenMapTiles is an open-source set of tools for processing OpenStreetMap data into zoomable and web-compatible vector tiles, which are ready to use in OpenLayers, Mapbox GL, Leaflet, QGIS as well as mobile applications. This talk gives an overview of...

Norway has deployed OSM on a national level for journey planning and is taking initiatives to expand the user, and usage of OSM in Norway and abroad. Entur’s mission is to enable and increase the use of public transport in Norway. Entur operates the national registry for all public transport in Norway, collecting data from 60 public transportation operators. The registry contains data about 21,000...

Services that provide money advice, access to food provision, digital access and community support are key to supporting those facing poverty. “Our Falkirk” is a simple mapping platform for service discovery that allows enriched OSM data to be easily described, mapped and shared through the concept of data ‘themes’. Falkirk Council is one of 32 Local Authorities in Scotland. Located in the centre...

We've learnt about many projects and clever systems that run OpenStreetMap possible, but it's the individuals that are most valuable in what we do. Settle down in your seats as Gregory introduces you to a selection of OSMers and informally chats to them about their involvement. When, how, and why did they join OSM? What do they do in the project? Has that changed? What's their favourite map tag? A...

OpenStreetMap enables people to use third-party apps that seem to be more suitable for privacy-conscientious users, but are we as users really private when using OSM-based apps? In mobile applications users generally don’t have control over what gets transmitted over the network. This means that people even in the age of the GDPR are not aware what they expose about themselves when using Android o...

This study adopts a statistical approach based on Exploratory Spatial Data Analysis to identify underlying contribution patterns of OpenStreetMap (OSM). Univariate and multivariate analyses on a number of variables computed from OSM history on a regular hexagonal grid in Milan (Italy) allow to detect a number of both local clusters and local outliers, which shed light on the complexity of OSM temp...

This presentation describes the nature and life-cycle of carto-vandalism through a data-driven analysis of harmful edits originated from Pokémon Go players. It also assesses how the OSM community reacts to vandalism. The utilization of OpenStreetMap (OSM) data by mainstream tech companies has been on the rise in recent years. Two prominent examples are Snapchat and Pokémon Go that became OSM data...

The talk describes the use of OSM as part of an asset management process using a crowd of National Trust staff, volunteers and the public to maintain an network inventory of an estimated 20,000 km of paths (both Public Rights of Way and permissive paths). The process pro-actively notifies local staff of changes to enable on-ground validation.  The process required the definition, and consistent ap...

An analysis of Notes, based on local experience of managing notes. Over 1 735 319 notes have been added to OSM, currently 416 224 notes are still open. Even looking at a small area such as Edinburgh, the city I live in, we have around 10 new notes added every day. It's interesting to note the motivation of people adding notes, many are added by regular experienced mappers for changes that need to...

The Tasking Manager is OpenStreetMap’s most used software tool to organize mapathons, community mapping initiatives and professional mapping teams. Over the last year it has been developed further significantly. This talk will give an update on the newest developments and the emerging community around the application. The Tasking Manager is OpenStreetMap’s most used software tool to organize mapat...

Den "Turingtest" zu erwähnen kann ebenso vielsagend wie irreführend sein - allzu verbreitet ist die Einschätzung, da "wisse man schon worum's geht". Der Aufsatz hinter dem populären Turingtest ist hingegen gemeinhin viel weniger vertraut. Schade eigentlich, denn die dezent-provokante Schreibe macht nicht nur Spaß beim Lesen, sondern wirft auch spannende Fragen auf. Dieser explorative Input schnapp...

There are 250 million refugees and IDPs in informal settlements that are routinely excluded from population and settlement datasets as well as Sustainable Development Goals (SDGs) assessments. Here, we share results from ongoing research to map and assess SDG indicators at global informal settlements using OSM data and satellite imagery. We present a new OSM-driven schema for monitoring SDG progre...

Who benefits from the mapathons: between (over)communication and (over)attribution, critical feedback on the inflation of a form of action oversold in the field of humanitarian action and development aid. Really for the benefit of OSM? It would be possible to multiply the subtitles for this "Mapathon, mapathon, mapathon!" talk which questions the almost mandatory use taken by this form of collecti...

Lightning Talks ## Human in the Loop: Verifying Machine-Generated Data for Better Maps Said Turksever Machine-generated map data has the potential to considerably accelerate mapping at scale. Combining it with human review helps ensure high data quality. We’ll show how a simple game-based tool helps verify the map data generated by Mapillary’s AI, and how that data helps enhance OpenStreetMap. ##...

Providing more validation checks with MapRules and MapCSS Tag Checks in iD and JOSM to direct mappers to issues as they map. As well as using Overpass queries to retrieve features with data quality issues. There is a need for validation in crowdsourced mapping to ensure that the quality of created data meets the community’s agreed upon standards and best practices. The OpenStreetMap community has...

Von Firewalls und VPNs hat wohl jeder schon gehört - jedoch sind die technischen Details häufig hinter GUIs versteckt, so dass man von den eigentlichen Abläufen dahinter nur wenig sieht. In diesem Vortrag wollen wir auf zwei neue Technologien in Linux näher eingehen: dem iptables-Nachfolger nftables und dem modernen WireGuard VPN-Tunnel. Wir greifen verschiedene Implementierungsdetails auf und zei...

The OpenStreetMap (OSM) community is a global community crossing cultures, languages, and geographical boundaries. Researchers have been working to develop automated approaches to understanding the composition of this community through their contributions to the OSM database. In this talk we propose a new and novel application of theories and models of species abundance from ecological science to...

Our data model is impractical. You know that. Even OGC Simple Features are better. Changesets and versions promised easier reverting — is it simple yet? We have added a lot of features to API 0.6 over the past ten years, but should we have? Let's see what went wrong and what we can improve. People often come to me saying, changesets with huge bounding boxes are impossible to validate. Come on. You...

The OSM data model has facilitated rapid growth of community-created geodata which third parties can build on. But as more accuracy is needed in routing, cartography, and other uses, is this data model good enough? We are trying to represent spaces as flows, which result in fundamental compromises and inaccuracies. This talk will discuss real-world cases where this compromise is increasingly probl...
