Der Vortrag stellt ein paar Lessons-learnt aus der Infrastruktur-Automatisierung mit Ansible vor, zeigt ggfs. nur am Rande bekannte Nice-to-Knows und gibt ein-zwei Tipps&Tricks zum persönlichen coding-Style. Was Ansible ist und wozu es dient, muß man inzwischen hoffentlich niemandem mehr erklären. Für einen Einstieg stehen hinreichend HowTos, Blogs und Dokumentation zur Verfügung - darüber hinaus...

Mit den Bibliotheken mynit und mytrix lassen sich einfach erweiterbare ChatOps-Bots mit MicroPython (z. B. auf ESP32) bauen. Microcontroller sind ein spannendes Thema, gerade für Einsteiger*innen – denn oft helfen Dinge, die man sehen und anfassen kann, beim Verstehen abstrakter Themen, wie der Programmierung. Doch um ein kleines, schnell einsatzfähiges Gerät zu bauen, gibt es schon einige Hürden...

Der Betrieb sozialer Plattformen benötigt erhebliche technische Ressourcen und verursacht entsprechend hohe Kosten. Zentrale Plattformen sind für Venture Capital Investoren interessant, da die Daten und der Content der Teilnehmer gut monetarisiert werden kann. Die Wertschöpfung der Teilnehmer dezentraler Netze kann der Betreiber einer Fediverse-Instanz dagegen nicht monetarisieren. Die Struktur de...

We're all now experiencing that remote working and virtual conferencing are important tools to stay connected. Not just in current circumstances but also in the wider future. That's why it's important to offer an easy-to-use, efficient, and quick replacement. Nextcloud is a platform for complete online collaboration and communication and can help to quickly adept and stay connected. Nextcloud is b...

The MapOSMatic web frontend allows to create printable maps from OSM data interactively. This is not the only way to use its rendering backend, it is also possible to directly use its ocitysmap Python library to render maps from your own Python code and a local stylesheet and database setup, or to use the REST-like API of the web frontend to send automated render requests to a MapOSMatic web insta...

Every day hundreds of people sign up for OpenStreetMap. We have several active OpenStreetMap communities, communities that are struggling to sustain themselves and at the same time, there are countries with no existing OpenStreetMap communities despite having contributors from those countries. This idea of a community playbook is to act as a guide for persons interested in starting up an OSM commu...

The geospatial world is moving to cloud-first and cloud-native approaches. Movements like STAC and COG have transformed how people use raster data in the last couple of years. OpenStreetMap has much to gain from thinking about different cloud infrastructure architectures. This talk will discuss what it takes to run the OpenStreetMap ecosystem in the cloud and present the history and work on a proj...

Coverage of `maxspeed` data in OpenStreetMap is very sketchy (about 12%). This situation is unlikely to change because the limits are often not signed explicitly. So, data consumers such as router software need to compensate huge holes in the data with more or less rough estimates based on other data. This talk shall explore a method how to infer default speed limits for different vehicle and road...

Digital maps are ubiquitous tools in our everyday life. In the early 90s, the idea of browsing the world digitally and visiting any place was groundbreaking. The first solution to this problem is known as "TerraVision", which was breathtaking. Today, the idea of exploring your surroundings using digital maps has become normal. But how do these maps work? In this talk, I want to provide an overview...

Designing hyperlocal maps starts with understanding the users in their day-to-day journey through some user research method and why the current digital maps experience does not provide a complete experience for them to navigate and explore the neighborhood. This talk will provide the audience the insights into the mobility lifestyle of the local people in tier 2 cities and how the GrabMaps design...

OSM has an unrestricted tagging model. Mappers can invent and use any tags. While this is part of OSM's success story, it has lead to a database where the globe is described in ever greater detail. In this talk we want to explore how users of OSM data handle a tagging model with so few constraints. Richard, the owner of cycle.travel, and Sarah, maintainer of Nominatim, team up to share their exper...

Pre-recorded lightning talks submitted in advance by people around the world. ## Our Top 10 Data Quality Aspects _Samson Ngumenawe_ [HOT](https://www.hotosm.org/) works with a number of organizations and communities that generate data through different contribution mechanisms, including desktop digitization, data collection surveys and local knowledge experiences. Each of these mechanisms lead to...

Christopher Beddow takes us on a journey of how to map a small town using a variety of tools. The goal was to test and prove how much OpenStreetMap can be enriched using RapiD buildings and roads, and Mapillary map features, traffic signs, and imagery. He evaluates a small town in the western United States that is far from any mapping community and has very little data, and demonstrates how a vivi...

The OSM data model with its nodes, ways, and relations has done an amazing job for us over the years. It has seen very little changes since relations were introduced 15 years ago. But there are some real problems with the data model. With the experience of those 15 years behind us, its time to tackle some improvements. This talk will outline the problems with the data model, show ideas for improve...

Through open mapping, we hope to inspire local youths and leaders to use technology to improve and create sustainable local governance system. We engaged 44 youths from 3 municipalities to participate in open mapping in first phase. In second phase, we gathered 10 IT officials from province 2 and highlighted OSM to connect geospatial elements for better local-level administration. Here, we will di...

Understanding the limitations of data is hard. Some tags are missing, and some tend to be present only when others are. Is the missing tag saying something, is it just unknown? When tags take yes/no values, is a missing tag an implicit "no", maybe the tag "does not apply", or something else…? This talk doesn’t have answers. It’s the journey we took through an investigation of road data in London....

We would like to share our feedback on facilitating OSM participatory mapping workshops for climate change adaptation projects with OSM local communities Since 2015, CartONG has been expanding its work into the domain of participatory mapping, first by partnering with the international Missing Maps project, and then by working to develop a wider set of tools and methodologies. Over the last 12 mon...

OpenStreetMap consists of tagged nodes, ways and relations. Many use cases of geographic data, however, need a tabular dataset of points, lines and polygons. Processing OSM into derivative datasets is a crucial task that can benefit from new tools and formats. This talk will cover several topics around this theme, including: * Existing approaches such as the Export Tool * Why FlatGeobuf is a suita...

Lightning talks ## AddressForAll Institute _by Thierry Jean_ ## ImproveOSM new data dumps _by Beata Tautan-Jancso_ The ImproveOSM platform is a suite of tools to share various mapping tasks containing potentially missing one-way tags, turn restrictions, and roads from the OpenStreetMap. The ImproveOSM data is also available as frequent data dumps in CSV format. ## Geohash plugin _by Beata Tautan-J...

Boundary conflation is a sensitive and difficult problem to solve. When administrative boundary data is available from authoritative sources for OSM, it is imperative that we have the ability to analyze boundaries for import and deduce if conflation with OSM ways can be done hopefully in a semi-automatic fashion. "Admin Boundary Conflation" is a special-purpose tool made for the purpose and this t...

Usability testing can be done without hordes of users to observe, in fact just three people is likely to give very useful hints. And it is almost certainly more useful than expected, and your software is likely not as good as you expect. This is based on my experience with using user testing while developing StreetComplete. about this event: https://2022.stateofthemap.org/sessions/EHZQXV/

By 2025, HOT aims that communities in 94 countries vulnerable to disaster or experiencing multidimensional poverty are equipped and able to map the locations where they live and work. We believe that accessible mobile mapping tools are key to this effort. Since I started working for HOT in January 2022, I have done informal interviews, observations, focus groups and experiments with more than 100...
