[1] The FOSSGIS booth at the Young Congress for Geography
Mapping
- Voting is open until Monday, 13 October on these proposals:
beauty=*to indicate a hair salon’s specialisation in women, men, or mixed clientele.information=*, a top-level tag defined as infrastructure intended to convey information.
Mapping campaigns
- Microsoft’s Open Maps team is updating Brunei’s boundary data in OpenStreetMap, using open sources including geoBoundaries, adhering to OSM guidelines, with all edits done manually, properly sourced, and marked with the #MSFTOpenMaps tag.
Community
- In the latest series of OpenCage’s OpenStreetMap interviews, Ed spoke with Thibaut Maïto, an OpenStreetMap contributor from Lyon, France.
- Nick Doiron has visited and mapped Herm Island and Sark Island, both part of the Crown Dependencies in the British Isles.
- Paul Norman has noted that the current OSMF vector tile service contains code from Street Spirit, a general-purpose vector tile map style, which was started before the OSMF vector tile project (we reported earlier).
- Andy Townsend experimented with the Nominatim geocoder to test whether it could return a hierarchy based on one plausible geographic scheme, the traditional English counties, as compared with the administrative ones.
Imports
- The French city of Échirolles shared
a page on the OSM wiki explaining their methodology for maintaining their local tree database, which includes exchanges with OpenStreetMap via semi-automatic control work, with the aim of keeping the data lifecycle synchronised between OSM and the local database. With the LeBonTag software, the latest contributions to OSM are validated and integrated into the local PostgreSQL database, while a Python script allows new objects or updates created from the local repository to be transferred back to OSM.
Local chapter news
- [1] Katja Haferkorn reported
►
on FOSSGIS’ participation in the Young Congress for Geography, held in Leipzig 17 to 20 September, which featured several sessions dedicated to OpenStreetMap. - The 24th FOSSGIS Community Meeting was held ► at the Linuxhotel from 19 to 21 September, with a full report
► available on the wiki. The 25th FOSSGIS-OSM Community Meeting is scheduled for 30 April to 3 May next year.
Education
- Dmitry Polovinkin has written an article ►, in which he explained how OSM differs from other maps and showed the basics of editing objects.
- rtnF shared several QGIS lessons he learned while studying an online course, on the HOT Learning Center platform.
►OSM in action
- Jake Coppinger has published a blog post utilising traffic signal site relations to map government traffic signal timing data in Sydney, Australia. The published maps are interactive observable charts.
Licenses
- German state Rhineland-Palatinate has given permission ► to use their orthophotos or terrain data. You can already use them in JOSM. ID will follow soon.
Releases
- GeoDesk has released version 2.0 of its OpenStreetMap toolkit. The new GOL Tool is lightweight (<1 MB, no JVM required) and 2 to 10x faster (importing the planet file takes ~15 minutes on a modern workstation). The release also adds an interactive query mode and instant map visualisation.
Other “geo” things
- Google’s new policy of mandatory verification for Android developers publishing their apps outside the Play Store has called into question the future of F-Droid. F-Droid is a free and open-source Android app store that offers, among other things, numerous OpenStreetMap editors and mapping apps that use OpenStreetMap.
