Emma Goldman, Morris Vinchevski, Morris Rosenfeld, David Edelstadt, Josef Bovshover, Jacob und Katharina Merison sind so bekannte wie unterschiedliche Figuren, die im sozialistischen...

Am 7. März 2021 hat das Schweizer Stimmvolk den Vorschlag für eine privatwirtschaftlich betriebene E-ID wuchtig abgelehnt. Kurz darauf verlangte das Parlament vom Bund eine vom Staat herausgegebene und Privatsphäre schonende E-ID zu entwickeln. Seither sind mehr als drei Jahre vergangen. Nun möchten wir herausfinden, was der aktuelle Stand bei diesem Projekt ist. Am Abend sind Annett Laube, Profes...

Openstreet map has for a long time been treated as a road map, enabling you to find a route between two points, as well as an information map, gathering various points of interests. Together with students of the UKEN University from Krakow, we decided to look at the use of OSM as a environmental map also showing the transformation of space by humans. The speech is the result of exercises conducted...

OpenStreetMap Foundation Board Ask Us Anything (i.e. AMA). We will take questions from the audience, or other questions that people can submit before the event, and we will talk about and answer them. We can talk about the past actions of the board, and what future plans we have. This is a chance to ask the OSM Foundation Board questions, to engage with the board. Let’s have a conversation about t...

This talk presents a systems perspective analysis of events in October-November 2023 which started with large-scale vandalism of OpenStreetMap data in Israel and ended with the introduction of rate limiting. Noting how the project reacted in face of this unique situation and the undermining of its basic assumptions facilitating the project helps uncover resilience- and vulnerability-inducing mecha...

Following a theoretical and methodological analysis of the scientific literature on PGIS, this study aims to explore the unexplored potential of the connections between PGIS (using OSM) and digital humanitarianism, as well as the empirical references from a case study in Morocco. INTRODUCTION / BACKGROUND Considering that NGOs and International Organizations have been applying PRA methodologies to...

So you want to improve the map of your village or city. How do you do that — install Mapillary and go cycling? Print a map and use a pen to draw over it? Install an editor app and go tapping buttons? Just try to remember everything and bring it home to map in JOSM? Let's see what tools we have and how to make the best map with no money and lots of enthusiasm. Ground surveying for OpenStreetMap has...

This paper presents the learning outcomes of a Mini-Mapathon course developed, implemented, and evaluated for the first time in a population of 28 Asian Junior high school ELL students in three Human Geography courses at an international high school. The paper includes an introduction to crisis mapping and concludes with an analysis of students’ knowledge and skill gains, and attitudes towards map...

Lightning talks are short presentations (maximum 5 minutes) about a topic related to OpenStreetMap. ## Hot course in OSM data use (new course!) _by Sam Colchester_ ## Hot OpenSummit '23-24 _by Geoffrey Kateregga_ ## OSM Malawi: Insights into the contributions of the OSM community _by Priscilla Kapolo_ ## The growth of OSM community in Zambia (Local knowledge mapping) _by Priscovia Ng'ambi_ ## QFie...

A discussion of the results of a survey distributed to corporate editors working in OSM. In recent years, OpenStreetMap (OSM) has evolved from being a Volunteered Geographic Information Project to one of the most successful Geospatial Crowdsourcing Platforms in the world. Volunteers, governments, and corporations all make contributions to its global map. Corporate editors (CEs) are the latest entr...

About work on reducing one of minor problems of OpenStreetMap: rare, unclear and confusing tag values. Such as for example shop=mięsny How cleanup of such tags may help? Why it is dangerous to make this kind of edits? How it can be useful and how it can be problematic or annoying? How it can be done so benefits are much greater than damages? What kind of help would be welcome? Creative Commons Att...

This talk will look at corporate editing in OSM at three scales - global, national and local. Our results show that corporate editing increased from 2016 to 2021, but has decreased since then. Nevertheless, in recent years there has been a diversification of corporations, with an increase in edits from Digital Egypt or Grab and other smaller corporations. Corporate mapping tends to focus more on h...

The research evaluates the accuracy and completeness of wind and solar energy infrastructure data in OpenStreetMap (OSM) for Belgium and Ireland, identifying common mapping errors and proposing techniques to enrich available data. By combining OSM data with CORINE Land Cover inventory, we study land use patterns around renewable energy infrastructures, facilitating environmental planning. We are w...

In recent years, advancements in 3D city models have been instrumental in urban planning and public engagement. In Japan, over 200 cities have adopted open digital twin data in CityGML format as promoted by Project PLATEAU of the Ministry of Land, Infrastructure, Transport and Tourism. This initiative, detailed in Binyu et al.'s research and the 3D City Index report, involves collaboration with th...

Whether they are man-made or natural, disasters pose serious risks to communities all over the world. A comprehensive evaluation of gasoline station infrastructure is necessary to ensure public safety and reduce fire dangers. This research, which focuses on Harare, Zimbabwe, uses Geographic Information Systems (GIS) to examine building patterns and access building footprints, road networks, and pu...

OpenStreetMap (OSM) provides detailed street networks essential for analyzing active transportation (AT) infrastructure. However, the granularity and inconsistencies in OSM data pose challenges in modeling AT users' movements at the street level. This study proposes a novel methodology to generate axial networks for AT users using OSM data, simplifying the network while preserving topology. Applie...

This presentation describes with how to use command line tools to create MapLibre GL style. I recommend to use...

Our work aims to assess OSM road data quality with a focus on car driving. Current work-in-progress proposed indicators to assess attribute accuracy, with a focus on speed limits and methods for estimating the logical consistency of road data. Due to the crowdsourced nature of OpenStreetMap (OSM) and the lack of quality control during the contribution, the data quality issue has become a research...

Starting as a small research project at the University of Bonn and later the University of Heidelberg at around 2008, Openrouteservice has been steadily growing since. This ensures that now almost 120,000 users get free and equal access to basic mobility solutions every day. With the release of version 8, this conference talk will give you an exclusive behind-the-scenes look at almost a decade of...
