Mapping

  • Warin, who noticed a new mapper trying to map a golf course, complained to the tagging mailing list about the current wiki page describing how to map a golf course. That triggered a lengthy discussion on the mailing list, where we discovered that it makes sense to consider even the grass height in recognising the tee area.
  • Leo Gaspard would like the landuse=highway tag to be used more often as he wants road areas to be tagged along with their surfaces. However, as noted during the conversation, the widely used area:highway=* includes an optional surface tag already.
  • Danilo reported on the Swiss mailing list (de) his experience with creating his own aerial images with a paraglider. He mentioned the project opendronemap.org, a toolchain for processing aerial imagery. His example result (large file) looks promising.
  • How many traffic light nodes should be added for complex intersections? This question was raised (de) in the German forum. The conclusion was to tag traffic lights for pedestrians with highway=crossing and crossing=traffic_signals to avoid multiple time penalties when routing cars over an intersection with multiple traffic lights. The possibility to add the direction of traffic lights was also mentioned.
  • The Open Knowledge Lab Karlsruhe has created a map that shows farm shops, market places and vending machines for food and milk in Austria, Germany, Switzerland and some neighbouring regions. They explain the map and future plans in the German forum (de). If you want to join the development or make your own map for your region, you can find the project on GitHub.
  • Warin61 has created a proposal for ephemeral water, i.e. water that is only present for short duration.
  • The voting for the tagging proposal aeroway=highway_strip is under way.

Community

  • The OSM API is currenly running slower than usual because the master OSM server is moving from Imperial College, London to the Equinix data centre in Amsterdam. In the transition period, a slower server in York, England is serving as the database master server (we reported earlier). The OWG is looking for volunteers from the Amsterdam OSM community to help during the move on 25 and 26 July.
  • OSM US has not found the right person for the new position of an executive director and is still waiting for more applications.
  • OSM Belgium has chosen Lionel Giard (OSM Anakil) as mapper of the month and published an interview with him about his way of contributing.
  • chris66 found an object during his field survey which was treated as a land mine by the police. His finding resulted in the arrival of an Ordnance Disposal Unit and was reported in a local newspaper. He received tips in the always-helpful German forum (de) (automatic translation) on the different ways to tag a crater.
  • The voting for the OSM Awards ends on July 26th. Please vote if you have not done so already.
  • The media platform TriplePundit published a story about the benefits of collaborative problem-solving. It mentioned the well-known code creation and mapping efforts for disaster relief but also forward-looking development aid such as openRMS, an open source enterprise electronic medical record system platform for resource-constrained environments.
  • [1] Rixx published a blog post about the orientation of streets in European cities. He wrote a Python script, which
    he made available on GitHub, which shows the direction that a city’s streets run in most often. He continues the work of Geoff Boeing who wrote a blog post "Comparing City Street Orientations" using his OSMnx Python library. In a description of OSMnx Christoph linked to a number of blog posts about OSMnx use cases ranging from figure-ground diagrams over isochrone maps to network-based spatial clustering.

    Mapbox catches up with its own version and presented a slippy map with streets orientations. In a blog post they explained their implementation that is available at GitHub.

  • The company Uber uses OSM internally for fare calculations and to optimise driver and rider matching as they have explained in the forum. The team in Palo Alto will start fixing bugs found in OSM by Uber drivers in the Delhi region in India as a test. According to their forum post, they will share the profiles of the editors on Uber’s OSM page, will follow the Organised Editing Best Practices and Indian guidelines, and do not plan to make large-scale, machine-generated edits.

OpenStreetMap Foundation

  • The OpenStreetMap Foundation has published a report highlighting OSM and OSMF related updates. Regular readers of the weeklyOSM may have heard some of the updates already but there is also a lot of new information such as working group insights in the report.

Events

Maps

  • The outdoor map provided by Andy Allan’s commercial Thunderforest Platform is now rendering difficulty classifications based on sac_scale.
  • Skinfaxi introduces a new service of meaningfully cut out topographic maps for Sweden and the southern neighbouring countries on a scale of 1:50.000, which can be downloaded as PDF. Unfortunately there is hardly any documentation (example as PDF).

switch2OSM

  • User jbelien has published an article in the OSM user diaries on why one should use OSM instead of Google. The article was originally written for the Open Summer of Code 2018 in Belgium. If you prefer the article in French, voilà.

Programming

  • Have you ever been impatiently waiting for your large changeset to finish uploading? Then you might be interested in the blog post from mmd. He wrote about a new, faster changeset upload implementation that has been developed and is available for testing now. Instructions on how to help with testing are included in the blog post.
  • A new version of GeoPandas, an extension for Python’s data science package Pandas, was just released. GeoPandas extends Pandas’ data types and allows spatial operations on geometric types that would otherwise require a spatial database such as PostGIS. The new version 0.4.0 improves the performance and behaviour of the overlay functionality. Further, there is a long list of other new features and bug fixes.

Releases

  • The version 1.3.0 of Maputnik, a free visual style editor for maps, has been released.
  • Wambacher’s software list was updated as of July 17. The almost endless list shows the current versions of OSM related software.

Did you know …

  • … that Thomas Konrad created a website showing the coverage of buildings in Austria compared to public data. While he considers Austria as a whole nearly complete (with coverage greater than 85 percent), there are still areas with coverage below 50 percent where some work needs to be done.
  • … of Pascal’s website Unmapped Places? The intention of this tool is to detect under-represented regions a.k.a. “unmapped” places in OpenStreetMap. Basically it checks whether a road can be found within 700 m around a place= tag or otherwise it will be flagged as unmapped.

Other “geo” things

  • The German blog beyong-print published a post (de) about the start-up cartida that is offering art prints of maps based on OSM data in different styles and sizes. Currently they only ship to Germany, Austria, France, Netherlands, Belgium and Luxembourg but they plan to add more countries.
  • govtech.com, an online portal covering information technology’s role in state and local governments, reported that Google’s new API restrictions will have minimal impact on goverment bodies. From July 16 onwards, Google Maps requires an official API key and a valid credit card attached to the account in order to work. However, state and local governments prefer using paid products from ESRI, Mapbox and Boundless Spatial for their work.
  • The Mississippi’s Board of Licensure for Professional Engineers and Surveyors sued the company Vizaline, which provides banks with polygons on satellite images for use in granting loans. The Board says that it should be the state entity solely responsible for land surveying.
  • It is no secret that new edits do not always improve the data in OSM. A research study now provided some more insight. The conclusion was that the completeness and positional precision of features can be improved up to 14% if you take the history data of objects into account.
  • Mongabay, an online platform for environmental topics, published an article about MapHubs. MapHubs is a commercial platform storing maps and spatial data for viewing and analyzing. Paying users can use public and private data sets to create customised maps showing deforestation and generate time-lapse videos in "minihubs" called websites.
  • The website visualising data published the 53th episode of its "the little of visualisation design" series. The series focuses on small design choices and demonstrates with a sample project in each episode. Using an article from The Guardian, the website explains in the current episode the use of thumbnail map images that helps orientate the viewer.

MapRoulette 3 1

Mapping

  • Jeremiah Rose asks, on the tagging mailing list. if it is feasible to provide links to accessible restaurant menus. He suggests two possibilities for the tag syntax: url:menu=* or url:accessible_menu=*.
  • OpenStreetMap announced,via an official blog post, that Bing Streetside imagery is available in the online editor iD. Streetside is now the 3rd available street-level imagery in iD together with OpenStreetCam and Mapillary. The blog post says that Streetside will “probably become available” in other editors like JOSM. Please note before using this imagery that the licence from Bing has certain restrictions.
  • Martijn van Exel has released the 3rd version of MapRoulette. MapRoulette will give you a random task in OSM to work on. Since 2013 about 1.5 million tasks to improve OSM have been completed. Martijn is blogging about the new features of in a series of posts. His first post is concerned with the introduction of location, category and text based filters.
  • On the German OSM forum (in German), a user came across a trap street on another map. What should OSM show? Let the cat out the bag? An interesting discussion ensues.
  • If you like sauna you might be interested in the new proposal. It is trying to bring order into the current muddle.
  • A member of Amazon’s Logistics team has asked (de) in the German forum how they can address missing turn restrictions to OSM mappers. They fear that OSM notes could be left disregarded.

Community

  • On the talk mailing list, Frederik Ramm mentioned a scientific paper about imports into OSM and their effect on the local mappers’ communities. The answers mention the varied impact of imports around the world and in the history of OSM, and therefore exclude any universal recommendation for imports.
  • Pablo Sanxiao does a good job explaining (es) (automatic translation) that OpenStreetMap is not actually a map, but rather a database filled with geospatial data, continuously updated and improved by volunteer mappers and other actors, alike.
  • [1] Martijn van Exel also introduced his new tool Meet Your Mapper. It shows you the mappers and their number of contributions in any area based on a relation ID as a table. It also allows you to export the statistics.
  • Only 11% of the streets in Rosario (Argentina) are named after a woman.

OpenStreetMap Foundation

  • The OpenStreetMap web site and API will be read-only for around 30 minutes starting at 10:00 UTC on Sunday 15th July, whil the services are migrated to an alternate data centre. (Tweet)
  • The company Cesium, a US based company offering services around 3D maps and Geospatial data analysis, announced that it is now a corporate OSMF member.

Events

  • FOSS4G Tokail will be held Aug 24th and 25th at Aichi University.

Humanitarian OSM

  • HOT has held Community Knowledge Sharing Webinars between July 11th-16th to share experiences of 15 HOT communities about the topics gender, youth, advocacy, data integration and Leave No One Behind.

Maps

  • The uMap 1.0.0 release candidate was announced on the mailing list. Major changes are the merger of Leaflet.storage and django-storage, the move to Django 2.x, which does not support Python 2.x anymore, an improved permission panel, easier customisation, filtering and unicode markers.
  • A thread on searchandrescue subreddit brings to attention the combined pitfalls of OSM’s (but not only) incomplete data about hiking trails and renderer’s grouping choices. The discussion was started by the case of hikers who followed a challenging hiking trail on OSM, that was rendered exactly the same as an easy trail by the app they were using.

switch2OSM

  • As our colleagues from the OSM-US twitter team have noticed that the company ESRI has created a vector map with OpenStreetMap data to match OSM’s default carto style that can be viewed online.
  • Bing maps is now using building data from OSM in their proprietary maps. If you zoom in, you will see OSM based buildings and an OSM attribution. If available, Bing uses height information from OSM to render 2.5D building models.

Open Data

  • Opendata.ch, the local Swiss chapter of the Open Knowledge Foundation, has hosted their annual conference. As the Swiss newspaper Netzwoche wrote (de), the topics included challenges, open data politics and an outlook as usual but also a lessons learnt about a project that struggles to sustainably finance itself due to on-off interests in the project.
  • Mateusz Konieczny has written a new tutorial for learning how Overpass-Turbo is used. It is supposed to be useful also for people without any knowledge about OSM and without any programming skills.

Software

  • Daniel from Mapbox, writes a diary post about how to run the full RoboSat pipeline on your own imagery using drone imagery from the OpenAerialMap project, taking the area of Tanzania as an example.
  • Mateusz Konieczny describes how screenshots may be generated using a relatively simple Python script. Easy to update screenshots are likely to be useful in documentation like tutorials.

Programming

  • Michael Spreng has started to implement a better integration of the Overpass API in Umap and is looking for help with the front-end.
  • Peter Karich from the company GraphHopper, wrote a blog post about the visualisation of road network reachability with deck.gl. Although network reachability visualisation is nothing new, the blog post describes how you can create fancy visualisations of reachability yourself.

Did you know …

  • … the app OSMfocus? The open source app shows you the tag/values pairs of objects around you and makes it much easier to identify objects that need an update when passing them by. The source code was recently made available on GitHub and you can install the Android app from Google Play

Other “geo” things

  • Ian Webster created Ancient Earth globe, a 4D visualisation of the Earth in various moments of the distant past – going back to 700 millions years ago. Better not use this for mapping those coastlines.
  • Starting from iOS also third-party navigation apps can use Apples car integration Carplay. Sygic announced such a first integration, which uses OSM as one of many sources. Mapbox also offers an integration via their Software Development Kit.
  • You might not do so, but please do not write down names from door bell nameplates during mapping. Even your hand-written notes can be seen as a “file” as the European Court of Justice ruled against Jehova’s Witnesses. 😉
  • The Australian website spatialsource wrote an article about the MapXplorer’s new web-based un|earth:: app. The app allows you to browse through Landsat images and the changes over the last 32 years. The app supports simple image manipulation capabilities but is limited to Australia.
