Löten gehört zum Grundhandwerk des gemeinen Hackers. Wie oft muss man mal eben zwei Kabel verbinden, ein Bauteil aus einer Platine austauschen oder eine Schaltung zusammenlöten. In diesem Petit Foo wird erklärt was löten ist, was man dazu benötigt und wie man richtig Elektronik lötet. Am Ende habt ihr das nötige Wissen um am verteilten Lötworkshop teilzunehmen. about this event: https://www.chaosp...

Man kommt oft nicht umher und muss sein Projekt oder seine Idee anderen Leuten vorstellen. Ich werde heute im Petit Foo erklären, worauf man beim Präsentieren achten sollte und wie man typische Fehler vermeidet. about this event: https://www.chaospott.de

"Computer, schalte das Licht aus!" ist dank smarter Lautsprecher keine besondere Funktion mehr, sondern Alltag in vielen Haushalten. Eine umfangreiche Smarthome-Ausstattung haben jedoch nur wenige. In diesem Petit Foo wird erläutert welche Techniken es für das Smart Home gibt und worauf man achten sollte. Besonders wird darauf eingegegangen wie die Clubautomatisierung in der Foobar umgesetzt haben...

A/B Street is an open source traffic simulator built on OSM and public census data, easy for the general public to use. This talk will cover some case studies of A/B Street being used to advocate for cycling infrastructure in Seattle, and describe how to use it anywhere. A/B Street (abstreet.org) is an open source traffic simulator built on OSM and public census data. It simulates car, bicycle, fo...

Global dataset and a map style for hiking and biking developed from OpenStreetMap - that's MapTiler Outdoor. During development, we have to solve multiple challenges originating from a lack of international standardization in trail marking. MapTiler Outdoor is a global dataset and a map style for hiking and biking available as a zoomable and web-compatible vector tiles, which are ready for use in...

Describes current situation of people using and appreciating OpenStreetMap data without being aware at all about its source. Describes how it violates OpenStreetMap license and proposes to start enforcing it. OpenStreetMap is not really known among people. But it does not mean that they are not using it. I was talking with a pair of tourists using maps.me to navigate. They commented that OpenStree...

During the past decades, the European Commission has invested billions in research through various programmes, such as H2020. In this study, we review exhaustively all the H2020 open deliverables to analyse how these public european projects are relying on OpenStreetMap. Since 1984, the European Commission has been supporting research through various successive programmes. Recently, from 2014 to 2...

Since now 10 years, the Overpass API allows to query the OpenStreetMap data. This is reason enough to show how OpenStreetMap and the Overpass API have changed over that timespan. I will present and overview over user statistics, technical challenges and all kinds of requests to me as the developer. Since now 10 years, the Overpass API allows to query the OpenStreetMap data. This is reason enough t...

The rise of organized editing practices in the OpenStreetMap community has outpaced research methods for identifying mappers participating in these efforts and evaluating their work. This research uses machine-learning to improve upon prior approaches to estimating corporate editing on OSM, contributing both a novel methodology as well as summary statistics that shed light on corporate editing beh...

I explore the spectrum of web map rendering techniques between raster and vector, and outline new approaches towards making universal map applications with OSM. OSM's mission is to create a free, global dataset of geodata for diverse applications. A mainstream OSM use case is **web cartography**: the graphical display of geographic features on the standardized browser platform. Cartographers want...

We develop and test user embeddings approaches to vandalism detection in OSM. We successfully demonstrate improvements to previous vandalism detection methods, and additionally how the user embeddings can further be applied to detect different communities of mappers. We validated the embedding model with a prepared vandalism corpus that we are also releasing to the OSM community. With more than 11...

This track gathers various lightning talks of 5 minutes each. ## Being ohsome with R *Oliver Fritz* | *[ofr1tz](https://www.openstreetmap.org/user/ofr1tz)* How to query the ohsome API from R to aggregate and extract elements from the OSM history. ## Introducing tilemaker 2.0 *Richard Fairhurst* | *[Richard](https://www.openstreetmap.org/user/Richard)* Vector tiles are great! Having to maintain a r...

It Consists in a proposal for a QGIS Plugin for Spatio-temporal analysis of OSM data quality in an area of Brazil. The development of methodologies to evaluate geospatial data quality is one of the most important aspects to be considered while obtaining these data. For the developing countries, such as Brazil, the lack of investment for the maintenance of the topographic mapping, especially on a b...

Organized mapping and institution / corporate based mapping keeps rising in the OpenStreetMap community. This talk is inspired by my observations whilst performing Quality Assurance as part of my personal OSM contributions in Ghana; highlighting some problems, solutions and recommendations. Many contributors be it, a hit-and-run, enthusiast or institution are using our ONLY OpenStreetMap data, and...

This talk presents results of an experiment conducted on the temporal accuracy of OpenStreetMap, and provides insights into the temporal dynamics with which changes in real-life appear in OSM. The ability to provide timely information compared to traditional collection methods of geographic information is generally considered as one of the main advantages of volunteered geographic information (VGI...

We look at interactions between Corporate and Non-Corporate Editors as reflected through co-editing patterns in the OSM data. We use Social Network Analysis on 12 networks generated from four different locations and 3 different timepoints and our results show the vibrant co-production of OSM data generation. There are interactions between all editors but Corporate Editors tend to interact at a hig...

OpenStreetMap (OSM) constitutes a new open geographic database and offers several possibilities of adding local knowledge. While the importance of local knowledge is largely acknowledged in the OSM community, relatively few scientific studies have evaluated them. This study presents a framework to measure local data contribution in OSM in three case studies. The results highlight a framework for m...

Machine Learning is incredibly popular at this time among researchers working with OSM data and on OSM-related problems. But what impact has this work on ML had on the OSM database or OSM community? We investigate the impact on OSM, if any, the ML work within the academic research community has had over the last few years. # What has machine learning ever done for us? Peter Mooney and Edgar Galvan...

NLMaps Web is a web interface for querying OSM with natural language questions such as “Show me where I can find drinking water within 500m of the Louvre in Paris”. They are first parsed into a custom query language, which is then used to retrieve the answer by queries to Nominatim and Overpass. Nominatim and Overpass are powerful ways of querying OSM, but the Overpass Query Language is somewhat i...

Between December 2020 to March 2021, the OSM Kenya team ran a project whose focus was on growing the OSM community locally: both in terms of membership and diversity. The project was supported through the Facebook and HOTOSM community impact microgrants. In this session, we will share about the community, project: from ideation(community health), motivation to implementation. This will include the...

Mappers see the OpenStreetMap Standard layer every time they view OpenStreetMap.org, but who else is using the layer? With usage logs, who is accessing what is broken down for this important OpenStreetMap service. The OpenStreetMap Standard layer is one of the high profile OpenStreetMap services, but not many people know who uses it, and where. This talk covers the goals of the service, it’s histo...

Pedestrians have been neglected. We’ve seen monumental progress in digital maps, but much of this has been road centric. In this presentation we download data from OpenStreetMap that relates to pedestrians to see how much it differs from the reality on the ground. We contrast different types of cities, seek to understand why pedestrian data is lacking, and look at solutions such as Mapillary that...
