Mapping

António Madeira announced on the Telegram channel of the OSM Portugal group the opening of the vote for the proposal for the standardisation of national built heritage drawn up by himself and user Jorge Pinho a few years ago, but which, due to lack of time, was never discussed or put to a vote.
The discussion will be open for three weeks from 00:00 on 15 December, followed by the vote. In addition to the mailing list, the proposal’s discussion page, the Telegram channel and the OSM Community forum are available for discussion.
Requests for comments have been reopened on these proposals:
- tourism=camp_lodging for tagging small, rentable buildings or shelters with limited amenities, designed for short-term lodging in natural settings.
- emergency=disaster_response for worldwide consistent tagging of disaster response service stations providing emergency response for civilians during or after a disaster.
Voting is open on:
- amenity=bicycle_wash to map bicycle wash stations, until Monday 18 December.
The vote on crossing:continuous=yes/no has closed. The proposal was approved with 32 votes in favour, one vote against, and one abstention.

Mapping campaigns

As of 1 January 2024, DB Netz AG and DB Station & Service AG will merge into DB InfraGO AG, requiring a comprehensive update of OpenStreetMap tags in Germany, Switzerland, Belgium, and the Czech Republic. Nakaner announced a manual edit of the affected operator tags.
MapRoulette has updated its basic OSM checks. There are many new challenges worldwide related to footway conflicting nodes, such as this one.
Two MapRoulette challenges have been created based on a discussion on the OSM Community forum about link rot in OSM data. These challenges aim to correct URLs in OSM tags that are no longer accessible.

Community

A regional YouthMappers ambassador wrote about achieving a historic milestone by successfully completing their very first national YouthMappers Summit in Bangladesh, setting a benchmark for their global network.
Approximately simultaneously, Jochen Topf and mcliquid each obtained permission to use the dataset of electric vehicle charging stations in Germany and Austria. The community is now discussing the possibility of an import.
On the OpenStreetMap Community forum, a new key, foot_scale=*, has been proposed to enhance path tagging for walking similarly to sac_scale for hiking. This scale ranges from casual_walking, requiring no special effort, to not_walkable, indicating paths unsuitable for walking. The intention is to simplify the representation of path attributes, consolidating various existing keys like surface and obstacle into a more straightforward scale.
Marcus Jaschen wrote ► about the significant growth of Geofabrik’s Europe extract of the OSM database, now around 28 GB, highlighting a steady increase. He has also updated his Gravel Overlay for bikerouter.de, detailing a comprehensive Ansible Playbook process for tile server updates.
Sakshi Verma, from India, is the UN Mapper of the Month for December.

OpenStreetMap Foundation

FOSSGIS e.V. ► , the German local chapter of OpenStreetMap, has committed to financially support the OpenStreetMap Foundation annually. This decision, made due to the size and financial resources of the German OSM community and their strong commitment to the project, is unprecedented for an OSM local chapter. For 2023 and 2024 the FOSSGIS board has decided to provide 10,000 EUR.
The Chairman of the OpenStreetMap Foundation, Guillaume Rischard, reflected in the 2023 chairperson’s report on significant developments and challenges in the OSM community. Key topics included the growth of OSM data, improved community discourse, strategic planning, and technical innovations. The need to strengthen the OSMF structure to enhance its efficiency and effectiveness is particularly emphasised. Join in the discussion here.

Local chapter news

Presentations will be streamed online, but presenters are expected to attend in person. The deadline for submissions is 11 February 2024.

OSM research

[1] Dr. Christina Ludwig successfully defended her doctoral thesis on mapping urban green spaces using OpenStreetMap data and Sentinel-2 satellite imagery. In her work, she analysed how green spaces are mapped in OSM and developed a mapping method that takes into account regional differences, incorporating both the fuzziness in OSM data and the limitations of satellite sensor resolution. This work significantly contributes to improving route suggestions for pedestrians and cyclists by recommending more pleasant paths through green areas.
A research project on predicting the transportation infrastructure in Indian cities has been published in Scientific Reports. The project uses OpenStreetMap and an innovative RidgeGAN method to analyse complex urban patterns and road network densities using machine learning and satellite imagery. This is an important study for urban planners and researchers working on sustainable urban development and improved transportation networks.
An innovative research project, published in PLOS ONE, uses satellite monitoring to identify the accumulation of terrestrial plastic waste. By employing neural networks to analyse data from the Sentinel-2 satellite, the system detects plastic waste in twelve Southeast Asian countries. This method identified more than twice as many waste sites in Indonesia, compared to OpenStreetMap and public databases, representing a significant step in monitoring and combating plastic pollution. National Geographic Indonesia reported ► on this.
A German-Austrian research team has analysed the mass of buildings and infrastructure in the USA in a study published in Nature Communications, revealing remarkable patterns in human-dominated landscapes. The study aims to provide a database for more sustainable use of resources.

In his OpenStreetMap diary entry, Sam Woodcock explained how he uses the PostGIS database to create FlatGeobuf files without having to rely on the extensive GDAL library. He described the process, which involves the use of SQL and SQLAlchemy in FastAPI, and highlights the benefits of this method for generating FlatGeobufs, particularly in terms of efficiency and ease. This approach offers an alternative solution for data preparation and management in geospatial applications.
