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.

Releases

Did you know …

Other “geo” things

  • North Road has summarized the new features of QGIS 3.0 in a blog post.
  • The location intelligence platform CARTO announces its switch to Mapbox, in order to provide fast rendering of big geodatasets, better geocoding and routing.
  • Spiegel Online interviewed (de) Heinz Vielkind, who draws ski slope plans and has to weight up between reality and usability.

  1. Rob diz:

    The following is wrong. It should read “that led to *the detection of existing* erroneous petrol station data within OpenStreetMap.”

    Thanks

    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.
