- Bobropiton made three videos(1, 2, 3)
about mapping bus routes and finding mislabelled routes. - The Asia Pacific Hub from HOT has compiled a list of most common data quality errors in OpenStreetMap per country and found some trends.
- Christoph Hormann outlined a method of choosing what to render for compound names based on the
default_languagetag. - Valerie Norton (User Valhikes) reports about her mapping activities based on field trips from February to September 2022 in Calico. See also her other "Moments in Dirt and Ink", e.g. about Fort Narraguinnep or the Dangerous Park.

Maps
- [1] Andy Townsend wrote that his Garmin maps are coming along nicely. You can download pre-made files for Great Britain or roll your own.
- dcz had a dream of the perfect map for their cycling trip. Using TileMill and OSM data the dream became reality but the cycling trip didn’t.
Open Data
- Adrion explains how to download, convert and import the National Heritage List for England into Vespucci and Orux Maps to use it for mapping.
- The Câmara Municipal da Horta, a municipality on Faial Island in the Azores, Portugal, released traffic direction changes
> 
using OpenStreetMap, including credit to contributors. - Kai Johnson blogs how he and watmildon analyzed changes in GNIS data to find potential additions and corrections for OpenStreetMap in U.S.A.
> Software
- Anthon Khorev’s ‘osm-note-viewer’, can now be used with other openstreetmap-website-based projects. He explains more in his blog.
- Pieter Vander Vennet has compiled some statistics about Open Reviews. Besides the official demo application, Mangrove, MapComplete‘s implementation is most popular.
- Planet Lite, the copyright-free map of the entire world, from MapTiler has been upgraded with enhanced features. Some issue fixes in the lite version of MapTiler Planet complete the update.
Programming
- Hans Thompson shares a script in R language to query elements from OSM and show them on a browser map using the leaflet javascript tool. He uses farmer market POI’s (
amenity=marketplace) in his example. - Hungerburg explained >
how he usedjqJSON manipulation commandline (linux utility) to parse and get an overview of a very large geojson government open data file (in this case roads in Tirol). - Do you ever get confused by Overpass Query Language syntax? Now, you can highlight syntax elements in some editors: Visual Studio Code + vscodium compatible editor, and KDE’s Kate.
- Inspired by a video (we reported earlier), rtnf decided to make his own self-hosted vector tiles.
> Releases
- osm2pgsql 1.8.0 has been released. Thanks to PostgreSQL 15 osm2pgsql is even faster.
- OrganicMaps released a new version with improvements in KML import, proper elevation handling for hiking and cycling.
