The age of POIs on OpenStreetMap the USA [1] | © Martijn van Exel | map data © OpenStreetMap contributors
Mapping
- [1] Martijn van Exel tooted some choropleth maps of the age of POIs on OpenStreetMap in the US. These used the same database, populated with osm2pgsql, as RestoBot (we reported earlier).
- Martijn van Exel found that his 360° imagery became sharper, and more readable for OSM tagging purposes, if he mounted the camera sideways.
- iboates noted everything you need to know about mapping electric vehicle charging stations. He put special focus on capacity tags and explained when it is unnecessary to specify the number of cars.
- ltog noticed that, in certain circumstances, the iD editor suggests extracting a POI node from a building outline, which, if no further action is taken by the user, results in a duplicate node in exactly the same location. In his view this suggestion may be inappropriate in many use cases.
- The MapWithAI Twitter account suggested deleting buildings which are already mapped to allow building outlines extracted from satellite imagery to appear in their place within the editor. As a reminder, good practice is instead to replace existing geometry, so as not to lose building history, as Tom Hughes explains in response to this tweet.
- Peter Elderson blogged about mapping embankments and all their details.
- SK53 posted two new instalments of his diary post series about unusual things seen whilst mapping solar power in Wales. The first discussed stone circles built in modern times and how to tag them. He believes this is one example of a more general issue when objects fall outside the original scope of the main tag usage.
- In his second post, SK53 described how he used open data derived from old maps from around 1900 to locate disused windmills on the island of Anglesey. He pointed out that the technique is applicable to a wide range of historical and archaeological features.
When Richlv revealed on Mastodon that his mother is an expert on Latvia’s old windmills, SK53 pointed out the Windmill World site based on OpenStreetMap data.
- Matt Whilden has used GNIS data and MapRoulette to improve the mapping of mobile home parks in Arizona.
- Yivan000 has compiled a summary of the numerous standards and tagging practices being used to map subdivisions in the Philippines. He explained his tagging standard, which aims to be more fitting for subdivisions.
- The proposal
► for standardising the mapping of Parque Escolar in Portugal has entered the voting phase. For more information, consult the project’s wiki page or the group’s official channel on Telegram. - Voting on
emergency=water_rescue, for mapping water rescue bases, has finished. The proposal was successful with 20 votes for, 3 votes against and 0 abstentions. - The proposal to replace
*:signedwithis_signed:*was rejected with 6 votes for, 10 votes against and 0 abstentions.

Mapping campaigns
- Since July 2022 Sahil Dhiman (sahilister) has done an exemplary job of mapping in OSM all schools in Chandigarh (we reported earlier). As he shared in his blog post, he is now turning his attention to the schools and colleges in the neighbouring town of Panchkula.
Community
- OSM old-timer Gregory Marler, aka LivingWithDragons, was interviewed as OSM Belgium’s Mapper of the Month.
- Ohene123 has written a brief outline of a project about women being under-represented in the OSM community. She is asking for people to fill out a survey on this matter.
Imports
- Pieter Vander Vennet has analysed the outcomes of the Visit Flanders mapping campaign after one year (we reported earlier). He summarised that using map notes for a guided import works well for small imports (<100 nodes). For bigger datasets (especially if >500 points), he recommends MapRoulette as an alternative.
Local chapter news
- The OSM Belgium chapter has sent out their latest quarterly newsletter. It includes a call to help with mapping their top tasks.
- USGS, the US national mapping service, published a guest blog about the OSM US Trails Stewardship initiative (we reported on the current status recently).
out their latest quarterly newsletter. It includes a call to help with mapping their Events
- Geoffrey Kateregga provided a detailed breakdown of how State of the Map Tanzania 2023 went about choosing technology to enable the conference to be run in hybrid mode. He also includes learning points from their actual experience. This advice should be invaluable for others planning similar events.
- Volker Krause, well-known in the KDE world, described his activities adding to KDE Itinerary at the recent OSM Hack Weekend in Karlsruhe.
- OSM US tooted some important deadlines for the 2023 State of the Map US. The first, for scholarship applications, had already passed on 10 March before we went to press.
switch2OSM
- Owen Boswarva noted the irony of the UK Government using a map based on OpenStreetMap to locate events around the coronation of Charles III. Over the nect 10 years, according to Peter Wells, the same government will spend almost £1,000 million making official geospatial data available to national and local government bodies.
Software
- kwiatek_123 has written osm_easy_api, which is a Python package for parsing OSM diffs and communicating with the OSM API.
Programming
Releases
- Julien Minet (juminet) has compiled some details of the latest version of OpenArdenneMap, a cartographic style for topographic maps.
Did you know …
- … Simon Poole has an improved version of the JOSM presets?
Other “geo” things
- The Overture Maps Foundation is seeking an executive director to be employed by The Linux Foundation.
- This week’s #Geoweirdness thread from OpenCage was about another French speaking nation, Canada.
