Mapping
- The proposal to specify ordering-only phone numbers, SMS-only phone numbers, and related tags is open for voting until Monday 29 July.
Mapping campaigns
- [1] During project days at Margarete-Steiff-Gymnasium, students collected
and entered ► data for OpenStreetMap and Wikidata using tools such as StreetComplete, Walking Papers, and OsmWikidataLink. They mapped local points of interest and georeferenced data, linking information between OSM and Wikidata. Activities included mapping buildings with house numbers, learning about geographic data structures, and presenting their work at the school festival with interactive projects such as Wikidata Guess and Wiki Trivia. - As part of the OSM-US Trails Stewardship Initiative, trail data in southern Utah has been improved to reduce environmental damage and increase safety by correcting digital trail maps, such as identifying and closing unofficial routes that affected the habitat of the Mojave Desert tortoise.
- Martijn van Exel has counted OpenStreetMap changesets that mention MapRoulette, or its short link domain (mpr.lt), and shared the results.
- In Padua Municipality, Italy, technicians appointed by the municipality partnered with citizens to utilise ► OpenStreetMap for mapping plans under the Elimination of Architectural Barriers initiative in infrastructure planning.
