Mapping

  • As part of a series on how to generalise OSM data, Jochen Topf shared his insights about the generalisation of river networks.
  • In Cochabamba, Bolivia, the Trufi Association is encouraging users of their app to contribute informal transport routes using a simplified mapping feature.
  • Bobropiton has made three videos(1, 2, 3) about mapping bus routes and finding mislabelled routes.
  • HOT’s Open Mapping Hub – Asia Pacific has compiled a list of the most common data quality errors in OpenStreetMap by country and found some trends.
  • Christoph Hormann outlined a method of choosing what to render for compound names based on the default_language tag.
  • Valerie Norton (valhikes) reported about her mapping activities based on field trips from February to September 2022 in Calico. See also her other ‘Moments in Dirt and Ink’, for example about Fort Narraguinnep or the Dangerous Park.
  • Voting for the proposal to consistently extend the usage of utility=* to service and industrial landuses, buildings and cabinets has closed. The proposal was approved with 19 votes for, 4 votes against and 1 abstention.

Community

  • OpenCage published an interview with the OpenStreetMap Somalia Team on their blog.
  • Grant Slater shared his insights about the development and benefits of OSM, making reference to volunteers mapping South Africa’s power grid, among other aspects.

Imports

  • watmildon showed how the US National Address Database can assist in cleaning up TIGER tagging.

OpenStreetMap Foundation

  • Board members of the OpenStreetMap Foundation shared their personal visions for 2023 and promised in the comments that a collective vision will follow soon.

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 explained how to download, convert and import the National Heritage List for England into Vespucci or Orux Maps to use for mapping.
  • The Câmara Municipal da Horta, a municipality on Faial Island in the Azores, Portugal, is notifying of traffic direction changes using OpenStreetMap, including a credit to contributors.
  • Kai Johnson blogged on how he and watmildon analysed changes in GNIS data to find potential additions and corrections for OpenStreetMap in the US.

Software

  • Anthon Khorev’s ‘osm-note-viewer’ can now be used with other OpenStreetMap website-based projects. He explained more in his blog.
  • Pieter Vander Vennet has compiled some statistics about Open Reviews. Besides the official demonstration application, Mangrove, MapComplete’s implementation is the 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 shared an R script to query elements from OSM and show them on a browser map using the Leaflet JavaScript tool. He used farmer market POI’s (amenity=marketplace) in his example.
  • Hungerburg explained
    how he used jq (a Linux command-line JSON manipulation utility) to parse and get an overview of a very large GeoJSON data file (in this case, a government open dataset of roads in Tirol).
  • Do you ever get confused by Overpass QL’s syntax? Now, you can highlight syntax elements in some editors: Visual Studio Code and other vscodium compatible editors, 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 than before.
  • OrganicMaps has released a new version with improvements to KML importing, and elevation handling for hiking and cycling.

Did you know …

  • … Lorenz Matzat’s 2017 article ‘How OpenStreetMap can be used for journalism? The article is still relevant today and deserves more coverage.
  • … ivanbranco has a list of his favourite OSM tools? He has recently updated the list.

Other “geo” things

  • OpenCage has published the question and the results for January’s Geotrivia on their website. Would you have managed a chain of 10 countries like Ciarán Ferrie and rubpec? On Friday 24 February Ed will set the next task.
  • -karlos- has created two puzzles from an OpenStreetMap map using the tool Jigidi. You can find some other puzzles on Jigidi if you search for OpenStreetMap.
  • On 25 January it became apparent that the source code for various Yandex services had been leaked. The source code for Yandex.Map was included, in which users have found code to work with OpenStreetMap data (but with a note about the incompatibility of OSM data with other sources).
