Mapping

  • Satoshi IIda (User nyampire) (ja) announced on Twitter (1, 2) (automatic translation) (automatic translation) about a new aerial image source in Japan. OSM now has permission to use aerial imagery published as open data from Itoigawa city and Atsugi city. He has published this imagery as map tiles and explains how to use it on the Wiki pages Itoigawa city and Atsugi city. (ja) (automatic translation, automatic translation)
  • The voting for the tag telecom=* has started. Values can include exchange, service_device and connection_point. This should enable mappers to map last mile networks and related equipment like DSLAMs (Wikipedia link).
  • A user of StreetComplete spotted complicated opening hours that don’t fit within OSM’s limit of 255 chars. Whilst all agree that the issue is not limited to opening hours, opinions as to whether such a level of detail should be stored in one value differ.
  • User jeisenbe proposes a comprehensive handling of default language format for names and places within a region. The voting on the proposal is currently under way: you’re welcome to review it and express your vote.
  • Nicolas Chavent produced a Twitter moment on the two weeks of capacity building action OSM, OpenData and free geomatics in Port-au-Prince (Haiti) organized in coordination with members of the association Communauté OpenStreetMap Haiti Saint-Marc (C.OSMHA-STM) for people from academic, research, development sectors and the local OSM community, thanks to the support of the Economic and Digital Directorate of the International Organization of La Francophonie
  • The new value landuse=governmental is proposed to mark land used by government bodies.

Community

  • On October 11 Nomad Maps finished his cartographic cycle tour through the Andes route having cycled 5000 kilometres. As a result more than 10,000 new objects were mapped and more than 100,000 additional photos added to Mapillary. He had 17 meetings with OpenStreetMap contributors in Colombia, Ecuador and Peru. As a cherry on the pie, Alban Vivert (@Nomadmapper) participated in SOTM Latam 2018 in Buenos Aires to present the results of the expedition and to meet other members of the OSM community. More info on Nomad’s blog and the website of Nomad Maps.
  • The “Schokofahrt” (chocolate tour) is a decentralized private bicycle tour for emission free transport of chocolate, to promote sustainable mobility and CO₂ neutral transport. At this year´s edition some stairs, that got in the way of the OSM based routing app BikeCitizens, were complicated to overcome with the heavily loaded cargo bikes. The map error was rapidly corrected.
  • Here are the videos for the State of the Map Latam 2018 sessions on September 24th in Buenos Aires, Argentina.
  • Sev OSM tweeted about two weeks of OSM and OpenData training in Conakry, Guinea.

Imports

  • Majka announced that an import of post boxes in Czech Republic is planned. The word import may be wrong here as it is mainly intended to update collection times and re-tag currently not active post boxes to disused:amenity=post_box.
  • Dannykath from Development Seed wrote about importing of data into OSM. The write-up covers topics like what type of data make sense to import, what is involved in the import process, what needs to be considered before starting, how to document and community involvement.
  • The Denver Regional Council of Governments is making a dataset available for importing to OpenStreetMap. It contains over 1 million building footprints, with an accuracy of 6 cm. Several import-a-thons will be organised for volunteers to review and ensure consistency with existing OSM data.

OpenStreetMap Foundation

  • Michael Reichert started a discussion on the OSMF list about the next Board elections: he suggested a slight change in the election calendar and a questionnaire for the candidates, instead of email flooding the mailing list. His proposal is getting positive feedback and further input on the subject.
  • Christine Karch from the SotM Working Group wrote a comprehensive summary (de) (automatic translation) about her activity over the past year. The ‘Way to SotM 2018’ titled article covers the preparations of the SotM 2018 and other tasks related to her job at this Working Group. She details how she was working on the scholarship applications, the organisation and evaluation of the submitted abstracts for the SotM workshops, lightning talks, talks and other events, the work on the tender for the 2019 SotM and many related tasks. In addition she gave a lot of insight behind the scenes. She explained how helpful it was to meet Nicolas Chavent and Séverin Menard to find a better balance and give the French/African part of OSM some more room and also explained why she thinks that no Code of Conduct for OSM is required. Some minor, maybe more controversial points in the article are her feeling of an overweight of HOT in areas like scholarship and diversity.
  • User Stereo (Guillaume Rischard) wrote in his user diary about the new Organised Editing Guidelines that were drafted by the Data Working Group and are on the OSMF board meeting agenda of Oct 18th. In his post he explains the context and motivations but does not answer to solitary critic on the content of the new drafted guideline and lack of community involvement during the development.

Events

  • This year’s Chaos Communication Congress (Leipzig, 27th to 30th of December) will host once again an OpenStreetMap-Assembly. More details on this event on the dedicated wiki page (in German).
  • The Europe Direct Office in Cuneo (Piedmont, Italy) has organised (it) (automatic translation) a full day around OSM, filled with talks, workshops and a mapping party. OSM will be presented by Marco Brancolini, OSM Piedmont coordinator for Wikimedia Italia; Alessandro Palmas, OSM Project Manager for Wikimedia Italia; and Cristiano Giovando, World Bank and HOT consultant.
  • A reminder that the upcoming FOSS4G event is on 25 October in Brussels. The planned schedule can be found here.

Humanitarian OSM

  • The 6th GeOnG forum will take place from October 29th to 31st in Chambéry, France. The GeOnG is organised by CartONG and includes topics like mapping and GIS, mobile data collection and many other technology related subjects that can be of interest in the humanitarian and development sector.
  • The English city St Albans is looking for crowdfunding to help visually impaired people with content for the app Soundscape. According to the article, the money will be used for a mapathon to train volunteers in OSM, verification and ongoing data maintenance.

Maps

  • The OSM-based London cycle parking map at stolenride.co.uk got an extra layer that can show the locations where bicycles were stolen based on police reports.
  • The New York Times used aerial images of the city Mexico Beach taken before and after Hurricane Michael and Microsoft’s building footprints to visualise the extent of the damage. The NYT identified 440 buildings of which 237 were destroyed and an additional 99 were severely damaged.
  • User SK53 wrote a blog post about how he created an OSM based raster map of the Irish Vice Counties with the proper Irish Grid, hill shading and hypsometric tints for use with MapMate, software intended to record, map, analyse and share biological sightings.
  • With Locator Map, you can now easily create locator maps in Data Wrapper. A location map is a simple map showing the position of a particular geographic area within its larger and presumably more familiar context. Locator Map is a new map editor to make this process as easy as creating bar charts. Try it here.

Software

  • Fabian Kowatsch introduces a new ohsome dashboard prototype as a preview on what is possible with the HeiGIT’s ohsome OpenStreetMap history analytics platform which is deployed on a distributed cloud system using Apache Ignite. You can explore the evolution of any available OSM tag over time in arbitrary areas of Germany and calculate some summary statistics.

Programming

  • In a blog post Alex-7 pointed to a prototype of an OSM map that generates Open Location Codes (OLC) for every position and, vice versa. One can also lookup a position based on the Open Location Code. It works without the need to add OLC related data to OSM.
  • ENT8R has added the filter parameters user name, user ID and time to the search functions of the OSM-API for Notes and documented the new functions in the OSM wiki.
  • Trafford Data Lab developed and documented a new Plugin for the Leaflet JavaScript library to show areas of reachability based on time or distance for different modes of travel using the Openrouteservice isochrones API. Included are various examples to get you started.

Did you know …

  • … Pascal Neis’ tool that generates a list of suspicious changesets based on different adjustable criteria? The results are also available as an RSS feed.
  • … the OSM changeset analyser OSMCha? It allows you to keep track of edits in changesets. Many different filters can be used when visualising changes in changesets.
  • … that you can invoke a username based filter with user:username when using overpass-turbo.eu?
  • … the OSM and NASA based map that simulates rising sea levels following a temperature increase. It allows you to simulate global warming caused land loss.

Other “geo” things

  • Benjamin Schmidt wrote the article Data-driven projections: Darwin’s world that shows the world map in a projection that centres around Charles Darwin’s route with his ship Beagle. The result is an interesting, but very unfamiliar perspective of the globe, with North America and Eurasia looking unimportant at the edge of the map.
  • The Relevator published an article showing the estimated regional change in rainfall and snow until 2050 caused by the climate change. The predicted change is displayed on an interactive map on a county level.
  • Microsoft has made a strategic investment in ride-hailing and on-demand services company Grab as part of a deal that includes collaborating on big data and AI projects.
  • [1] Neil Kaye published an animated gif on Twitter and Reddit that demonstrates the size of a country as shown in a Mercator projection compared to its true dimension.
  • A reader of Macrumors took photos of a man wearing a rucksack full of measurement devices walking along a street in San Francisco. The devices were LIDAR, GNSS and cameras for Apple Maps. Cars are also used for this purpose. In June 2018 Apple announced that they will not use third-party data in future anymore (we reported).

Mapping

  • The voting for the key assembly_point:purpose= has started. The key is is intended to be used with emergency=assembly_point where there is a need to specify the kind of hazard – fire, tsunami, earthquake, tornado.
  • Warin61 noticed that quite a few public transport route relations are broken. He describes the minimal requirements to make them pass the tests from GeoFabrik’s OSMInspector validation tool, which is a lot easier than having to go through the respective wiki pages documenting how to map bus and train route relations.

Community

  • For the third consecutive year members of the OSM Mali community hosted a week-long OSM training camp in Segou for students of the local university. About 70 students have been taught OSM techniques since 2016.

OpenStreetMap Foundation

  • Jinal Foflia explains the reasons and benefits of joining the OpenStreetMap Foundation (OSMF) and how to become a member. She also points out that a membership fee waiver program will be implemented soon.
  • OSM US welcomes their new executive director. Jaye Matthews was selected from more than 40 applicants for the newly established full-time position. She has more than 20 years of experience in non-profit leadership, but is completely new to OpenStreetMap.

Events

  • On October 19th a mapping party with specific focus on wheelchair accessibility will be held in Torino, Italy.

Humanitarian OSM

  • The Indonesian Tribunnews reports (automatic translation) about the efforts of OpenStreetMap Indonesia to map the area affected by earthquakes and the devastating tsunami around Petobo, South Palu based on DigitalGlobe imagery taken on October 2nd.
  • UBOS, Uganda’s national bureau for statistics, is taking an active role in mapping in OSM. Eleven core members have learned how to use JOSM, QGIS and mobile tools for surveying. There are many challenges to overcome in the country and OSM can help with that.
  • Matthew Gibb asked experienced OSM mappers for help with the validation of roads in the Florida Panhandle ahead of Hurricane Michael. A task was created for this on the OSM US tasking manager.
  • In September, faculty and students of the Centre for Interdisciplinary Methodologies, University of Warwick organised a workshop on “Making sense of humanitarian geospatial data to improve the impact of humanitarian interventions on health and wellbeing“. The workshop was co-convened by Médecins Sans Frontières (MSF UK), the Humanitarian OpenStreetMap Team (HOT), the Bangladesh Humanitarian OpenStreetMap Operations Team (BHOOT) and the Heidelberg Institute for Geoinformation Technology/GIScience Research Group at Heidelberg University. The event enabled participants to discuss current approaches and challenges and, most importantly, how to collaboratively address them.
  • It is October, so HOT commemorates open source by involvement in Hacktoberfest. It is an annual event hosted by Digital Ocean, GitHub and Twilio to promote contributing to open source projects. HOT reminds readers of over 15 of their own active open source projects.

Maps

  • Cartisan, a small Armenian-based cartography company, is creating a topographic hiking map of Dilijan National Park in Armenia. This will be the first modern topographic map set in Armenia. The map relies heavily on OSM data and the makers have greatly improved the OSM database in the area. The map (sample) is created exclusively with FOSS. They have launched a crowdfunding campaign, together with the local trail-building NGO, Transcaucasian Trail, to get the map produced.
  • Raymond Inzitari wrote a post about how he started a business making wooden maps as artwork. It took him over six months of development to build a model that uses OSM data, convert it to a geodatabase and output an AI file that is required for the laser cutter.

Open Data

  • François Lacombe asks whether OSM should participate in events such as the upcoming LinuxFoundation Energy Summit 2018. He argues that it is becoming increasingly common for energy infrastructure operators to replace proprietary data with OSM data.

Software

  • The next release of VROOM, free software to solve vehicle routing problems, will handle time windows constraints. The feature is already available for beta testing through the project’s demo server.
  • Sick of expensive map updates for your car’s built-in SatNav? A Raspberry Pi, an LCD screen and a few other components are all that is needed to create a DIY car navigation system that can provide free navigation based on OSM data overlaid on OpenMapTiles. The system can even include a rear view camera.
  • Generation Streets, a game available on Steam, is using OSM to render an impressive 3D environment.
  • Richard Fairhurst published a proof of concept for an OSM editor with a GUI that focuses primarily on street level imagery based mapping.

Programming

  • Due to Oracle’s slimming down and reduction of available functionality in their latest Java release, the OSGeo Foundation is organising a code sprint for their Java-based projects (e.g. Geoserver) at several locations from October 22nd to 26th, for which they are looking for sponsors.
  • The question whether the time has come to redevelop JOSM due to unpopular licensing changes in Oracle’s Java was asked on the mailing list. Responders point out that JOSM is compatible with the open-source Java implementation OpenJDK, and therefore does not require Oracle’s version of Java in the first place.
  • The avoid_polygons feature of the OpenRouteService API allows one to find alternative routes during flood events. To integrate real time information, a team of researchers at HeiGIT proposes a workflow to delineate flooded areas using Twitter data.
  • If you feel limited by how you can integrate a map into your website with Google Maps, Mapbox or Leaflet, you might want to have a look at the Vue.js framework and the d3.js library. Mikhail Panichev wrote a guide on how to create an interactive map with both of these JavaScript tools.

Did you know …

  • … JOSM’s angle snap feature? This feature helps you to add a line parallel, perpendicular or at defined angles to a base segment.
  • … the public transport map?

OSM in the media

  • Centésimo Mono published an interview with Carlos Brys. Carlos Brys reports about the first mapathon in the province Misiones and refers especially to the principle of data acquisition on site. (es) (automatic translation)

Other “geo” things

  • The Scottish Parliament passed a law banning public bodies in Scotland from making maps which display the Shetland Islands “in a box” (usually located offshore from Aberdeen or next to the Orkneys). Twitter has extensive commentary, and Kenneth Field, an ESRI cartographer, provides a detailed breakdown of why insets (“boxes”) are the sensible cartographic choice.
  • [1] The University of Heidelberg hosted a mapping session to show the power of crowdsourcing for map validation by collaboratively validating the land use and land cover map of Geneva with ESA’s Sentinel 2 and OpenStreetMap data. A preliminary version of the OSM Landuse Map can be found here.
  • Chris Wayne wrote an article about creating maps for visually impaired people. In his article he covers the two most common approaches to accomplish this, which are are tactile maps (maps you can feel) and auditory maps (maps that talk in the literal sense).
  • Another article that addresses the needs of blind people was written by Nicola Byrne. In her article she explains how to use 3D audio to guide blind people around cities, her experience with the system and how it works.
  • Friends of the Earth have published a 100 second video, with each second representing one percent of the landuses in the UK. The video asks whether nature has the space that it deserves.
  • The private blog addshore.com published an article about the increase in the number of Wikidata items over the past 6 months. The article gives a breakdown of the increase by region and mentions that the increase in Africa may be due to Wikimania 2018. Over the period about one million geolocalised items were added to Wikidata.
