Knotenzentralität

Visualization of the centrality of nodes using OpenStreetMap data 1 | Picture by Geoff Boeing

Mapping

  • Matej Lieskovský started a discussion on the mailing lists about how non-breaking spaces in name tags should be handled. Some languages, in this case, Czech, have rules about how a name can be displayed when split over two lines. The question is whether such rules should be enforced directly in the data in the OSM database or applied by data consumers.
  • Christoph Hormann has prepared new satellite layers of parts of the Antarctic and the Western Alps based on Landsat and Sentinel 2 satellite images. Amongst other things, he asks if they are suitable for mapping leaf_cycle.
  • Vespucci will support imagery from OpenAerialMap soon.
  • Voting for the proposal of piste:type=connection for connections between ski lifts and pistes is open, until February 8th.
  • The vote on the hydropower water supplies proposal was suspended due to pertinent remarks.

Community

  • Scott Davies tweets a rendition of buildings of Walthamstow, London, made with OpenStreetMap data using QGIS and Inkscape.
  • In France, a mapping party was held (fr) at La Fabrique Numerique, Gonesse where data were added to both OSM and Google Maps at the same time.
  • Post Mortem III: Randy Meech has written another post on the closing of Mapzen. It features the future of former team members and Mapzen’s products.
  • Reddit user BeFlatXIII starts a thread on OpenStreetMap about township mapping in Ohio, which results in rendering inconsistencies. Among the answers there are relevant links to OSM Wiki and to US mailing lists.

Imports

  • The plan of the import of buildings from the Spanish cadastre is already in its final stage.The import will begin as soon as possible, initially on Tenerife and in the city of Málaga.
  • Albert Pundt suggests improving county boundaries in Pennsylvania using TIGER 2017 data. The use of “Replace Geometry” from the utilsplugin2 JOSM plugin is recommended in the comments.

OpenStreetMap Foundation

  • The License Working Group of the OSM Foundation has published the FAQ on the recently enacted Trademark Policy along with other relevant documents.

Events

  • The call for abstracts for the Academic Track of the State of the Map 2018 is now open.
  • On April 14th and 15th, an OpenStreetMap hackweekend will take place in the DB-Mindbox in Berlin. Even sooner, an OSM hackweekend will take place on February 17/18 in Geofabrik in Karlsruhe.
  • 3rd of March is celebrated as Open Data Day. Join or organize one of the dozens of events around the world. Mapbox is supporting the mini-grants program to help local communities share the benefits of open data, particularly in Open Mapping. Find more about it here.

Humanitarian OSM

  • HOT reports on the refugee issue in Northern Uganda where up to 7,000 people a day are arriving, having fled from violence in South Sudan. HOT tries by providing equipment and training together with the refugees to capture Water points, also even sinking.
  • HOT, OpenStreetMap and ThinkWhere (a geospatial company in Scotland) get a mention in a UK parliamentary debate.

Maps

  • Franscisco Morales tweeted a Monde Geospatial video tutorial on how to download watershed delineation from OpenStreetMap for ArcGIS.
  • Ilya Zverev has revived OpenWhateverMap, originally created by Grant Slater. Have a look at the unusual rendering of the map!
  • The map style OSM-Carto will show military areas differently in the next version, see the pull request by andrzej-r with its examples.

switch2OSM

  • Niantic has updated its map data for PokemonGo and Ingress to the status of December 15, 2017. Unfortunately this also increases vandalism.

Programming

  • [1] Geoff Boeing wrote about easily measuring and visualizing street network centrality with OSMnx (Python) and OSM data.
  • Frederik Ramm suggests the introduction of a feature in the OSM API to allow moderators to rename user accounts, which he wants to use against obscene usernames.
  • The Heidelberg Institute for Geoinformation Technology is looking for a Software Developer (Web) for a limited period of two years.
  • Nakaner has released an Osmium-based C++ program called PrepDelRels that determines which paths become unnecessary when deleting a relation.

Releases

  • OSM-Carto has been released in version 4.7.0. An icon for tourism=apartment has been added and the entrances are now displayed. The full change list can be found here.
  • The new release of Mapbox Navigation SDK for iOS v0.13.0 comes with user location tracking in standalone map views, Danish and partial Hebrew localizations and Mapbox Navigation SDK for Android v0.9.0 opportunistically reroutes in the background, turn banner improvements including route shields and much more.

Did you know …

  • … the collaborative route planning platform FacilMap?

Other “geo” things

  • With Mapire historical maps can be compared with each other or with today’s maps/satellite images of OpenStreetMap and Here Aerial.

  • Indoor navigation in AR with Unity” – a blog post that shows how to use the Mapbox Maps SDK for Unity to create an augmented reality navigation application.
  • Here bought the indoor map startup Micello.
  • Microsoft Power User magazine speculates that the use of the Google Maps API on a recent Microsoft app presages the end of Bing Maps.
  • The Guardian reports about Strava heatmap revealing the location of secret US Army bases
  • TomTom discontinues the provision of what had been sold as “lifelong” data updates for some navigation devices (some actually still, or very recently, on sale). See also the comment by “Anonymaps” on Twitter.
  • Due to a military exercise, GPS disturbances and failures in the western USA are expected from 26 January to 18 February.
  • Brian Reinhart from the Dallas Observer has found that a lot of restaurants which do not exist in in real life are present on the Google Maps, and in services that rely on that. During his research it was easy for him to create and delete another imaginary restaurant. He wasn’t able to answer why they are there though – maybe someone just enjoys creating fake data?

Cookie Cutter

Cookie cutter by Christian Quest [1] |

Mapping

  • Open Data Institute Cardiff have announced a beta-test version Welsh-language map of Wales based on OpenStreetMap. It joins two other Celtic languages Breton and Irish which already have dedicated OSM-based maps. Carl Morris describes his approach to rendering. There are many Welsh names still missing from OSM.
  • Now that OsmAnd has started rendering deserts, Warin has started a thread on the talk-au mailing list about how to properly map them. The discussion mentions the climatic definition of desert and the difficulty in mapping fuzzy boundaries of such areas.
  • Daniel wrote about how to place motorway junction nodes — typically, those that connect a motorway to a motorway_link way — for improved routing. Discussions follow in the comments.
  • Reddit user Toxx8 asked for help on /r/openstreetmap about the import of an official dataset from Queensland, Australia, and the related licensing hurdles. The discussion is continuing on the talk-au mailing list.
  • Mappa Mercia writes a blog post about an import that led to erroneous petrol station data within OpenStreetMap, they have captured some of this and added it a “fixme” tag to it. This will help anyone to identify and fix these errors.
  • François Lacombe points out that the voting process on the hydropower proposal has begun.
  • Brian Prangle of Mappa Mercia writes an article about the future of phoneboxes in the UK. The plans include the removal of half of the phoneboxes and the repurposal of the others: Brian mentions the subsequent tagging challenges and the unfortunate unwillingness of British Telecom to share their data with OSM.

Community

  • [1] Christian Quest has been combining hobbies: baking cakes imprinted with the OSM logo.
  • Jan Kinne and Bernd Rensch from the Centre for European Economic Research have analysed location samples of software companies on a microgeographic level using OpenStreetMap data in Germany (Paper as PDF). The main limiting factor in accuracy is the absence of fine grained geospatial data on socio-economic demographics..

OpenStreetMap Foundation

  • The OSMF Board meeting that took place on January 18th was continued, and concluded, on January 25th.
  • OSMF published the minutes from the recent board meeting, Christoph Hormann (aka imagico) shares his views on the same as a diary post and that elicited lots of reactions from the board members.
  • The minutes of the meetings of the Communications Working Group of 19 December 2017 and 16 January 2018 as well as the data working group of the OSMF of 11 January 2018 are online.
  • OSM-US is seeking candidates for the upcoming board election. The post also sets out the goals for 2018: hiring an executive director, becoming an official local chapter and redesigning the web site.

Events

  • There is still time to apply for scholarships to attend the State of the Map 2018 conference in Milan. The deadline is February 14th. Some useful tips are provided for applicants to enhance their chances of receiving financial support from the programme.

Humanitarian OSM

  • The eruption of the Mayon volcano in the Philippines is featured on the HOT mailing list. Links to Tasking Manager’s tasks can be found in the resulting discussions.
  • Also in 2018 there are two promotion programs from HOT for OSM communities.
  • With the money from the non-governmental organisation Nethope, HOT has purchased computers and mobile phones in various countries and financed mapping training courses. Details can be found on the HOT website.

Maps

  • The GIScience Research Group of the University of Heidelberg announces a new version of OSMlanduse.org. Gaps in OSM data, for Germany only, have now been filled using machine learning methods on satellite imagery.
  • TravelTime Maps provide two interesting maps based on various sources, including OSM data: RadiusMap, which compares a simple ‘miles radius’ around a point with the travel times (isochrones), and the travel-time-only map, that includes walking, cycling, driving and public transport options.

Licences

  • A well-known city in Bosnia-Hercegovina asserts that it has full rights over its name.

Software

  • Fred Moine announces the availability of a French QGIS tutorial.
  • MapCat.com has revised the sidebar and displays additional information (opening hours, Wikidata) now.
  • Sarah Hoffmann explains the modified handling of post code areas and tags in Nominatim.
  • 5.25 million routes are calculated by the Matrix API of the OpenRouteService of the University of Heidelberg each day.
  • Zhuangfang from Development Seed writes a blog post on how one can create a building classifier to detect buildings in Vietnam. In this example, Label Maker will pull data from Mapbox Satellite and OpenStreetMap and prepare training data that is ready-to-use with MXNet in Amazon SageMaker, a service from Amazon Web Services (AWS) that enables users to develop, train, deploy and scale machine learning approaches in a fairly straightforward way.

Programming

  • WeRobotics has launched a competition for machine learning, which aims to identify roads, coconut palms, banana trees, papaya and mango trees on aerial photographs; but the prize is nothing but fame and glory. (Details)
  • The Heidelberg Institute for Geoinformation Technology at the University of Heidelberg searches for a backend developer (Java or C++). The contract is limited to two years.
  • Jan Marsch has published an SQL function for calculating rendering of shadows on Github.
  • Paul Norman guides his readers through the creation of a shell script for downloading planet files and extracts with robust error handling.
  • Robin Boldt, who runs Kurviger.de, reports in a guest article in the Graphhopper blog about their migration from Mapzen to the competitors and about which problems vector tile customers have to cope with.
  • HeiGIT developed a new open source “Realtime OSM Extracts” Service. It allows to automate the generation of the most recent OSM data extracts for arbitrary user defined regions in pbf format. For example these are needed during disasters for most frequent updates of maps and services such as the Disaster-OpenRouteService.
