- Andy Mabbett looked at some high-use wikidata tags and (while also noticing some accidental mistagging) raised the question whether each branch of a company should be tagged with the
wikidata=code of the parent or if -with the exception of the headquarters-
franchise:wikidataare better options to tag the belonging.
- Dave F wanted to know whether
junction=yeson polygons is used somewhere. According to the answers from Mateusz and Tobias, it is used.
- Valor Naram created a proposal for tagging baby changing tables and asks for comments.
- The tagging proposal Police Facilities, which was supposed to introduce additional detail tags for police facilities, has missed the approval threshold slightly.
- Leif Rasmussen has drafted a proposal for improving road lane connectivity information as he thinks that the current model with
turn:lanes=does fails to store all information for complex junctions. Simon Poole points to a similar proposal for a
transit=-key from 2015 that has been abandoned.
- Joseph Eisenberg wants to map plateaus, mesas, buttes and tablelands and asks on the Tagging mailing list for a suitable tag value for it. Various options are suggested; others believe that some large imprecisely defined areas that are difficult to verify on the spot do not really fit OSM’s data model at all, but should be stored elsewhere and made accessible to map stylists.
- Ilya Zverev announces the opening of nominations for the OpenStreetMap Awards 2019.
- OpenStreetMap is turning 15 this year and at the time of writing only one event has been scheduled so far. Thank you, Michael, for the reminder.
- The OSM Portugal Community has debated, through the mailing list Talk-pt, about the mapping of a new hospital on Madeira Island. If this hospital is under construction, how should it be mapped? If it is ready and closed, how should it be mapped? If it is ready, working without a license (and therefore illegal) how should it be mapped? Who should check the possible (i)legality of the operation? What should the mapper do? Map when to open without a license? Ignore until everything is licensed? These are some of the questions that have been asked by the Portuguese community. (automatic translation)
- Michael Reichert suggests (translation) an OSM-Wikicamp to discuss all the OSM-wiki related issues – and there are a lot of them. As he writes in his post, chances are that OSM’s local chapter in German, FOSSGIS e.V., funds the accommodation.
- The cleanup of our wiki gained some popularity recently. Apparently even pages which were deleted 7 years ago as been outdated still find readers today. Ilya Zverev criticised the deletion of a wikipage about the testing of the API 0.6. Unfortunately (but highly predictably) the following discussion about the wiki deletion policy derailed to a semantic dispute about the recent progress of the OSM API, the use of the word “vandalism” and the existence or non-existence of gatekeepers in OSM.
- API 0.6 turned 10 years last week: it went live on 21st of April 2009. Ilya Zverev recalls the history (automatic translation) of switching from API 0.5 and explains why he thinks we will never see a version 0.7 of the API.
- Grigory Rechistov prepared an import of forests, farmland and other types of land cover from Sweden’s Environmental Protection Agency and documented his plan in the wiki. Criticism voiced on the Imports mailing list seems to have been largely ignored.
- Christoph Hormann has discovered that the board meeting on April 24 contains a non-public agenda item about GlobalLogic.
- Rory McCann asks whether GlobalLogic indirectly pleads guilty because they offered to withdraw the memberships of their employees.
- Potential organisers can now apply for the State of the Map 2020. Applications close on June 15 2019.
- Christine Karch and Denis Helfer plan another OSM meeting in Strasbourg in May. The meeting, which will be scheduled every six months from now on will be held in German-French-English-Alsatian.
- Philip Pierdomenico introduced his recently created OpenStreetMap Coffee Map on Twitter.
- As Mapillary reports in its blog, the Departments of Transportation of the US states Utah, Florida, Arizona, Connecticut and Vermont have uploaded images covering 430,000 km of roads to Mapillary where they were automatically processed to detect traffic signs and other features.
- The Neue Züricher Zeitung reports (translation) about the origin and development of Wheelmap by the association Sozialhelden and introduces its founder Raúl Krauthausen.
- Owen Boswarva tweeted that the Canadian province of New Brunswick has completed its Lidar survey under the GeoNB Open Data Licence.
- Uli Deiters announced the release of 350,000 bollard positions (from 2014) by the city of Berlin as Open Data. He shows some nice visualisations and provides the data in shapefile format on GitHub.
- yaugenka filed a feature request for iD in 2017 to “unglue” an entire landuse area from a line with a shortcut. Quincy Morgan implemented this function recently and provided a short animation how it works.
- The PgAdmin4 Geometry viewer nice feature is added to PgAdmin4 since v3.3 with an OpenStreetMap background. While testing PostGIS scripts, programmers simply switch between Data And Geometry viewers and avoid moving data to other tools to visualize.
- jguthrie100 created a pull request for the iD editor which warns if an address is used multiple times.
- MapRoulette is now at version 3.3. The latest release adds a brand new review system. You can mark each task you solve as ‘review wanted’. Mappers can volunteer to review other mappers’ solved tasks within MapRoulette. Other new features include a new Portuguese localization and opt-in email notifications.
Did you know …
- … the new quality tool “Osmoscope” by Jochen Topf? It shows superimposed nodes as well as undefined or lonely nodes and ways.
-  … Parking Lanes Viewer by user ascd, with which you can view and change the mapping of parking possibilities at the roadside in OSM?
- … how to tag if a shop or amenity has a seating area? There are two tags for this:
outdoor_seating. For the outdoor gastronomy area there is the tag
leisure=outdoor_seating. In some places even the type of chairs has been mapped as
outdoor_seating:comfortor the type of
OSM in the media
- On El Pais’ article about the 2016 Spanish General Election showing voting maps. 11 of the 12 maps displayed on the article do not have the required attribution. The 2019 election was on 28th April.
Other “geo” things
- The Guardian reports about the fight of a man from Ilford, a London borough in North East London, for the postal code E19 which would indicates the belonging to London. He is concerned that than the current IG1 – IG6 is not always recognised as a London postcode and could be misread as part of Essex. His “fight” has lasted for 15 years now.
- Mapbox announced the release of its Vision SDK during the Shanghai Automotive Show. The SDK allows developers to add functions like augmented reality navigation and lane guidance, live traffic alerts and many others into own driving applications. The SDK also combines processed live data from sensors and cameras with classic map data, called AI Maps.
- Kenneth Field and Max Roberts show that schematic maps are a subject about which highly emotional debates can be carried out in public.
- A Blog Post from the Bill & Melinda Gates Foundation reports how collection of data at the local level with gps helps monitor Malaria desease with spatial analysis of the data.
- The National Geographic reports that the ice melt in the Himalaya will threaten more people to suffer from flash floods than thought. Researchers have included OpenStreetMap data in their investigations.
- Nico Belmonte, formerly head of visualization at Uber, has joined Mapbox as General Manager in charge of maps.
- You are invited to submit workshop- and presentation proposals for the URISA 2019 Caribbean GIS Conference, which takes place 18-21 November 18-21 in Port of Spain, Trinidad.
