OpenStreetMap has many details about streets, but applications rendering or simulating lane-level detail face many challenges: determining lane properties along one street, calculating geometry of streets and junctions, handling motorway entrances, dual carriageways, dog-leg intersections, placement tags, and parallel sidewalks and cycleways. osm2streets is a new effort to produce a cleaned-up str...

In this work, we present analyses using a series of comparative data insights that help to better understand the potential and implications of integration between knowledge graphs and OSM. OpenStreetMap(OSM) is one of the richest and most diverse sources of geographic information. However, it lacks a fundamental property vital for spatio-semantic analyses: hierarchical structure and semantic linka...

The United Nations Global Service Center (UNGSC) is developing Virtual Reality applications utilizing OpenStreetMap data. Through a Virtual Reality (VR) pilot project, UNGSC aims to provide UN peacekeepers on the field with 3D digital replicas of the cities in which they are operating, building a sandbox that enhances operational planning with simulations. In order to develop such applications, Op...

Sidewalks are a relevant part of the living space in urban environments, but there are still few mapped sidewalks. In recent years, the mapping of sidewalks has grown in importance among the OSM and academic communities. To cover up this gap, we propose a Github-hosted, fully open-source QGIS Plugin entitled "OSM SidewalKreator" to automatically draw for OSM the geometries of sidewalks crossings a...

A recent release of new scientific datasets generated from OpenStreetMap exemplifies the need for analysis-ready repositories of OSM data that require minimal pre-processing. We created the Analysis-Ready Daylight OpenStreetMap Distribution to provide researchers with the opportunity for simple cloud-based SQL queries of nearly 1B OSM features. We demonstrate the capabilities with intrinsic and ex...

The SDCC-STD-UX project funded by the Bundesministerium für Bildung und Forschung aims to improve standard compliance in SDCC, in particular support for current and future C standards. SDCC targets common 8-bit µC architectures, such as the MCS-51, STM8, S08,...

Albert Einstein's quote "If you want to know the future, look at the past." couldn't be more accurate today. Many young software engineers and graduates today were born in the early 2000s and only know the struggles of early software engineering from their older colleagues, the vintage computing community or abandoned books. Further, many developers from the early 90s are retiring now and there is...

In den letzten Jahren wurde die openSUSE-Infrastruktur deutlich verbessert. Aber ist sie jetzt perfekt? Natürlich nicht - sonst hätten die Heroes (= openSUSE Admin-Team) Langeweile, und ich könnte diesen Vortrag nicht halten. Wo Leute arbeiten, passieren natürlich auch lustige[tm] Dinge. Bringt bitte Euer eigenes Popcorn mit ;-) about this event: https://programm.froscon.org/2022/events/2780.html

Language barrier and the default to English puts non-English speakers at a systemic disadvantage throughout open mapping communities and humanitarian open mapping activities resulting in significant missed participation and impact. We held experimentation on language translations of key resources identified by collaborators coming from local OSM communities and we hope to share the findings in thi...

It’s easy to see how OpenStreetMap could be leveraged to improve the completeness and freshness of government geospatial datasets. So why aren’t all governments using OpenStreetMap? In the US, the ODbL license has prevented government agencies from using the data. Public Domain Map aims to resolve this (and other challenges) by providing a workflow that allows contributions to be used in both Open...

This session will provide an introduction to the OpenStreetMap operations team, what OpenStreetMap.org services we are responsible for building and maintaining. Grant recently became the OpenStreetMap Foundation's first full-time employee. Grant will present how he is helping improve reliability and security of the project's technology and infrastructure. Grant will detail how the Operations team...

During the 2019-2020 pilot supported by Microsoft, 18 million building footprints were automatically extracted from satellite imagery for all of Tanzania and Uganda. HOT found that on average, mappers working without AI assistance could map between 1000-1500 buildings per working day. For areas with high-quality AI output, providing mappers with AI-generated building footprint suggestions increase...

QGIS is one of the most used Opensource GIS software with some native functionalities to work with OSM data. Either with raster layer as a basemap, or with vector, QGIS can deal with OSM data. Depending on the amount of data to work with, the need to "refresh" the data (from the main OSM database), the extent of the coverage, different plugins or technologies are possible. This presentation will t...

Mapping is time-consuming and requires a high workforce when it comes to keeping maps up-to-date. Mapillary brings a different approach to geospatial data collection with street-level imagery. This approach allows communities to collect geospatial data faster and cheaper. But can Mapillary-generated data be useful for enriching OpenStreetMap? In this study, Mapillary-extracted map data will be exa...
