News from the world of OpenStreetMap No. 456 (04/09/2019 - 04/04/2019)

Notes Map, classifies OSM notes based on content ¹ | Leaflet | Map data OpenStreetMap contributors, ODbL - Imagery openstreetmap.de

Cards

• [1] miche101 introduced the Note Map , a tool that attempts to classify notes published on the OSM website according to their content. According to his post (automatic translation ) on the forum, he uses a dictionary of 774 words to sort notes into 25 categories.
• Qwant Maps got the ability to calculate the route (automatic translation ).
• Fork MapOSMatic (a tool for creating a city map and output to PDF) supported by Hartmut Holzgraefe, now uses the open source collaborative translation system Weblate instead of Transifex for localization.

Mapping

• Joseph Eisenberg has again begun the tag approval process camp_site=camp_pitch. In fact, this tag has already been used more than 6.8 thousand times in the zone tourism=camp_siteto indicate the place for setting up a tent or motor home.
• Joseph Eisenberg also suggested using a single tag instead of the existing tagging scheme for the tracks along which golf carts ( highway=pathor highway=service+ golf_cart=designated) move golf=cartpath.
• The tag shop=fashion_accessoriesproposed by SelfishSeahorse to designate stores specializing in the sale of fashion accessories is approved.
• Currently, the tag has been place=localityused almost 1.3 million times. Its scope is wide: they refer to as ghost towns and railway junctions in the United States and territorial division in Ireland ( locality=townlandand locality=subtownland). Therefore, Joseph Eisenberg suggests using a key locality=*to indicate the type of terrain.
• Since March 15, almost all addresses in Germany, which were made in the form of relations (associatedStreet), have been redone: they were applied to buildings in the form of tags. The proportion of excess relationships decreased from 58% to 7%. The user dktue posted simple statistics about this on the forum (automatic translation ).

Software

• The database history OpenStreetMap (OSHDB) received an update. Please check for fixes and new features on GitHub.

Programming

• Users of systems that use Osmosis to get changes should check to see if their system continues to work properly, since a diff was published on April 11th that Osmosis could not handle. You can see more information on this in the mailing list .
• At the moment, the OSM API is not able to work with downloads that were sent to the API and did not receive a response, for example, due to network problems. Most clients try to download their data again, and therefore it often happens that a new object is duplicated. Mmd started a discussion of this situation on GitHub.
• In the error tracking system of the iD online editor, there is a discussion of support for tags that are part of the "Object Life Cycle" tag group. The main developer quincylvania has already implemented this in the Git branch of lifecycle-tagging .
• Muratomo said that a new version of OpenSwitchMap has been released, which now works not only with the Chrome browser , but also with Firefox . This is a browser extension that allows you to quickly open the same place on different cards and services, including OSM validators, which can be useful to 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 has something in common with the OSM trademark.

Programs

• The site of the Children's card , useful to 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, but the road remains with the usual tag name. You can also add foreign names using a language suffix scheme such as bridge:name:ja. The same is applicable to tunnels: tunnel:name.
• ... about the site laengengrad-breitengrad.de (automatic translation ) for quick geo-coordinates conversion?

Other “geo” events

• Nick Weir, in an article published on towardsdatascience.com, talks about automatic image analysis and mapping, for example, when monitoring deforestation or disaster management. The article discusses the typical problems that automated solutions face: displacement and distortion of images, lighting, occlusion of objects and resolution. According to these parameters, he considers the five best algorithms for non-sack determination of the building development spot, which were proposed as part of the SpaceNet challenge.
• The Swiss newspaper “Tagesanzeiger” published a quiz on the cities of Sweden with graphics made by “Figuregrounder” , namely Hans Hack, who used data from OSM as the basis.
• The artificial intelligence Facebook team has made a map of Africa’s population density.
• Android Authority reports that Uber has paid $ 58 million to use Google maps between 2016 and 2018. Source of information - prospectus before IPO.
