OSM Unicorn Index
Moritz Schott

One of the pillars for success for OSM is the open nature of the project. Not only can any user add data of their choice to any location on the globe but also the geometry and semantics underlay no authoritative constraints. This results in a rich and diverse dataset.
In this analyses we inquire into one aspect of the datasets diversity looking at users editing behaviour. A new methodology to investigate the tendency of users to make edits that are rare or uncommon is proposed and a thorough data analyses is conducted. Analysing the detailed mapping practices of users in OSM can be a difficult task due to the data volume and the complexity. Using the OSHDB provided by HeiGIT we estimate the rarity of a certain map action by analysing how often said action is performed.
The analyses is twofold looking at tag changes on the one hand and edits to map features types on the other hand. Rare tag edits are actions that add or delete tags that rarely occur in OSM such as unique place names or uncommon opening hours. Rare map feature type edits are actions that e.g. change the geometry of relatively rare map objects such as hospitals or cowsheds - rareness is here defined based on the general abundance of the primary tag such as highway or building. Users are then evaluated based on their tendency to contribute these rare edits to the database. We call these edits unicorn edits as they are rare but make the map a more colourful place.
Our analysis shows that contrary to our assumption there is a large number of tags and map feature types that have only few contributions. As a result, a large share of OSM users in the analysed regions exhibits a rather high tendency to map rare elements.
An index is introduced, the so called unicorn index, that allows users to compare their tendency to make rare edits to other users in the same region. The presented analyses is limited to Heidelberg and Łódź but an interactive website is made available where users can compute their personal unicorn index for Germany and Poland as well.

The road map or the whole map. OSM in geographical research.
Paweł Struś

OpenStreet map is increasingly becoming an intermediary between us and the real world. We use a version of simplified reality of points, lines and relationships processed by volunteers. We ask a rhetorical question. Given the increasing density of information, could OSM be used for scientific research? Of course, this is happening, but could it be possible to ensure that at least small, compact areas - national parks, some specific spaces closed by borders - receive information as accurate as possible thanks to OSM? We tried it and we want to share some observations on this subject.

OSM’s wiki and documentation: make it fit – or accept a substitute?
Andrew Hain

OpenStreetMap has developed with a wiki approach to documenting its tags. Over the years the documentation has grown organically alongside a wealth of other information and projects. Twenty years of often well-meaning edits have led to pages that are sometimes difficult to keep up to date or to serve to mappers looking for assistance. This talk explores where we can go from here and how to get there.

How to leverage the democratic potential of map-based participation in municipalities? Harmonization efforts and policy reform
Mathias Großklaus

German municipalities are beginning to discover the potential of map-based citizen participation - sometimes, but not always using OpenStreetMap. Those projects however remain in a very narrow focus, catering only to niche audiences. But to reach their full democratic potential, a broader focus would be needed – and thus common technical standards and interoperability. In this talk, we will speak about our efforts to push for harmonization in the German smart city landscape and for a stronger role of the federal government in providing standards and infrastructure. With the audience, we will discuss a) the extent to which advocacy work should be carried out at the EU level and b) possible ways of involving the OSM community in those efforts.

Architecture of CREODIAS WMS Basemap for Very High Resolution Satellite Imagery from Copernicus Contributing Missions
Marcin, Michał Bojko

The latest addition to the data collections available on the Copernicus Data Space ecosystem is the Copernicus Contributing Missions data. These missions encompass existing or planned commercial missions from EU Member States or Copernicus Participating States, commercial operators of Very High Resolution (VHR) optical and radar missions, and other emerging European mission operators that provide some of their data for Copernicus. This collection is particularly interesting for the OpenStreetMap volunteer community due to the availability of high-resolution optical images that can serve as a basemap for vectorization. The WMS services to be presented combine data discovery, access, (pre)-processing, publishing (rendering), and dissemination capabilities available within a single RESTful (Representational state transfer) query. This gives a user great flexibility in terms of on-the-fly data extraction across a specific AOI (Area Of Interest), mosaicking, reprojection. The performance of the Copernicus Data Space Ecosystem and CREODIAS platform combined with efficient open software (Postgres 15 with PostGIS extension, MapServer with GDAL backend) allows achieving WMS service response times below 1 second on average. This, in turn, provides potential for massive parallelization of computations given the horizontal scaling of the Kubernetes cluster, and high availability of the data to be used without the need for downloading the original data in the most common spatial data editors such as QGIS and JOSM.

Production release announcement for fAIr, HOT’s AI assisted mapping community service
Anna Zanchetta, Omran NAJJAR, Kshitij Raj Sharma

fAIr is an open AI-assisted mapping service developed by the Humanitarian OpenStreetMap Team (HOT) that aims to improve the efficiency and accuracy of mapping efforts for humanitarian purposes. The service uses AI models, specifically computer vision techniques, to detect objects such as buildings, roads, waterways, and trees from satellite and UAV imagery.

The name fAIr is derived from the following terms:

F for freedom and free and open-source software. AI for Artificial Intelligence. R for for resilience and our responsibility for our communities and the role we play within humanitarian mapping.

The talk will announce the production release of fAIr tool that is available for wider OSM communities, illustrate the academic background and showcase the research developed in recent months to assess how the accuracy of the training process performs, evaluating the accuracy metric currently used and comparing against different metrics scenarios.

Quality assessment of OSM address points for selected administrative units in Poland
Marcin

As part of the research carried out into selected aspects of database quality OSM database, an analysis of a collection of address points collected in the database of OpenStreetMap (OSM) database for selected administrative units of Poland. This presentation presents the obtained results of the analysis. Validation was performed using appropriately developed tool and based on comparison of address data with the reference database State Register of Borders (PRG). The analysed descriptive and spatial features of the address data in the OSM, such as the name of the of locality, street, building number and coordinates, were compared in a specific way with analogous metadata from the PRG database. The analysis using an appropriately designed tool aimed to improve the quality of address data in OSM through systematic validation and comparison with reference data, as well as to developing good practices in the context of working with address data. A number of interesting results and conclusions in this respect. Furthermore, on the basis of the conducted tests and analyses, it was confirmed, among other things, that the state of addresses in OpenStreetMap depends on the the involvement of the community, which takes care of the integrity of the points. Relevant examples, including the possession of very good quality data superior to the timeliness of the state equivalent. Needs and directions for further research were pointed out.

Learnings from developing Microsoft’s Map builder UX
Milos Brzakovic

Openly sharing learnings from developing Microsoft’s Map builder UX/UI.

The key challenge Map builder UI is trying to solve is how to onboard users with no prior mapping experience to the world of osm editing, provide further education, and develop them into regular contributors.

In order to solve this challenge, product is built around the ideas of: keeping UI simple and minimal, educating and onboarding user through paradigm ‘learn by doing’, implementing step-by-step streamlined drawing and editing tools, keeping the sentiment of mapping fun and finally, emphasizing that map making is performed with and for a community.

Whilst doing so, certain tradeoffs and product decisions have been made which will be openly shared and the audience will be invited to brainstorming and discussion.

Maintaining public assets through OpenStreetMap-based infrastructure
pomodoren

Organizing the mobility infrastructure assets for small to medium institutions takes resources, that often they dont have. This makes it difficult to take decisions on priority for fixing broken infrastructure, scheduling maintenance, estimating costs, and predicting hazards.

ResMI is a tool for allowing several functionalities for institutions:
- Asset Inventory (includes cycling paths, bus stops, traffic signals, ...)
- Lifecycle management (activities like installation, maintenance, auditing, ...)
- Cost estimation (budgeting for asset type)
- Depreciation/Ammortization estimation based on institutional data (hazards including climate) or participatory (reported issues)

OpenStreetMap is used as a baseline database, and the attributes as a starting information for any municipality to get started. Then the inventory is expanded with new additional tags. The maintenance cycles are schedulable, and possible costs are either estimated, or overwritten. Topics like participatory reporting and climate change risk is included.
