• [1] Member miche101 presented the Note Map , a tool that attempts to classify notes published on the OSM website, depending on their content. According to his message (automatic translation ) on the forum, it uses a dictionary of 774 words to sort notes into 25 categories.
• Qwant Maps were able to calculate the route (automatic translation ).
• The MapOSMatic fork (a tool for creating a city map and outputting to PDF), supported by Hartmut Holzgrafe (Hartmut Holzgraefe), now uses the open Weblate co-translation system instead of Transifex for localization.

Mapping

• Joseph Eisenberg again started the approval process for the camp_site=camp_pitch . In fact, this tag has already been used more than 6.8 thousand times in the area of tourism=camp_site to designate a place to set up a tent or a tourism=camp_site home.
• Joseph Eisenberg also suggested replacing the existing track tagging scheme used by golfcars ( highway=path or highway=service + golf_cart=designated ) to use one golf=cartpath .
• Approved tag shop=fashion_accessories , proposed by SelfishSeahorse to refer to stores specializing in the sale of fashion accessories.
• Currently, the place=locality tag has been used almost 1.3 million times. The scope of its application is quite wide: they designate both abandoned cities and railway junctions in the USA, and territorial division in Ireland ( locality=townland and locality=subtownland ). Therefore, Joseph Eisenberg suggests using the key locality=* to indicate the type of terrain.
• Since March 15, almost all addresses in Germany, which were implemented in the form of relations (associatedStreet), were redone: they were put on the buildings in the form of tags. The share of redundant relationships has decreased from 58% to 7%. User dktue posted on the forum simple statistics about this (automatic translation ).

Software

• OpenStreetMap History Database (OSHDB) has received an update. Please check for fixes and new features on GitHub.

Programming

• Users of systems that use Osmosis to receive changes should check to see if their system continues to work properly, since on April 11 a diff was published that Osmosis could not cope with. Additional information on this subject can be found in the mailing list .
• Currently, the OSM API does not know how to work with downloads that were sent to the API and did not receive a response, for example, due to network problems. Most customers try to upload their data again, and therefore it often happens that a new object is duplicated. Mmd started a discussion on this situation on github.
• In the error tracking system of the online editor iD, there is a discussion of support for tags that are part of the group “Life cycle of objects”. The main quincylvania developer has already implemented this in the lifecycle-tagging Git branch.
• Muratomo said that a new version of OpenSwitchMap, which now works not only with the Chrome browser , but also Firefox, has been released . This is a browser extension that allows you to quickly open the same place on different maps and services, including OSM validators, which can be useful for any OSMer. A great contribution to the development of the new version was made by the developer F4map jazzzz. Soon the name of the project may change due to the fact that it overlaps with the trademark OSM.

Programs

• The Children's Card site, helpful and parents, has been improved .

Do you know …

• ... how to tag the name of the bridge, which is usually different from the name of the road passing through it? The corresponding tag is bridge:name , and the road remains with the usual name tag. You can also add foreign names using a language suffix scheme such as bridge:name:ja . This also applies to tunnels: tunnel:name .
• ... about laengengrad-breitengrad.de (automatic translation ) for fast geo-coordinate conversion?

Other “geo” events

• Nick Weir, in an article published on datascience.com, talks about automatic image analysis and mapping, for example, when monitoring deforestation or disaster management. The article discusses the typical problems faced by automated solutions: the displacement and distortion of images, lighting, occlusion of objects and resolution. According to these parameters, he considers the five best algorithms for the non-guided determination of the building development spot, which were proposed as part of SpaceNet Challenge.
• The Swiss newspaper “Tagesanzeiger” published a quiz on Swedish cities with graphics made by “Figuregrounder” , namely Hans Haq, who used data from OSM as a basis.
• The Facebook team involved in the development of artificial intelligence, made a map of the density of the population of Africa.
• The Android Authority publication reports that Uber paid $ 58 million for using Google maps from 2016 to 2018. The source of information is the prospectus before the IPO.
• A new version of the scenery editor for the X-Plane flight simulator has been released, supporting OpenStreetMap as a substrate. (automatic translation )

Community

• Tigerfell invites all Osmer members to vote on the approval of the rules for deleting pages and files from Wiki-OSM.
• Alan McConty shared his thoughts on unusual elections to the OpenStreetMap Council in the USA on his blog. Four candidates (John Adkins, Jan Deese, Brian Hausel and Alyssa Wright) were selected by direct vote, and one (Min Nguyen), who claimed the vacant seat after Maggie Cowley, was rated. Also in his post, Alan McConty talks about the details of electoral procedures. It should be noted that Maggie Cowley resigned just six weeks after being re-elected as executive director of OSM US.
• The Conversation , a news site for the academic and research communities, published an article titled "The Best Cycling Maps Made by Volunteers." The publication is based on a study of Canadian cities, which states that OSM contains the most relevant and detailed information in comparison with other data sources, including open data portals of the cities studied.
• Martin van Exel proposed a simple way to determine the extent to which a city is mapped in OSM. In his diary, he explained in detail why he decided to use the name= tag and POI as an indicator, as well as how to visualize the results of such an analysis.

Imports

• The Swedish community plans to import land use data from the Swedish Environment Agency (Naturvårdsverket). Discussion of this issue in the talk-se mailing list. (automatic translation )
• The Ministry of Agriculture, Forestry and Fisheries of Japan (MAFF) recently published (automatic translation ) farmland data for all of Japan. A Nyampire contributor wrote more about this huge dataset from 30,951,173 polygons. He concluded that the import "... may be difficult."
