Mapping

  • OpenStreetMap Guinea tweeted about the start of their mapping campaign to assist the fight against Female Genital Mutilation (FGM).
  • Jean-Marc Liotier noticed that schools in Senegal were converted from areas to nodes by multiple contributors, thereby losing information. He discovered, after some investigation, that this was done because of upcoming elections. The organisation wa mbedni, behind the project “Senegal Vote”, was the culprit. The reason is baffling though: they can’t process surfaces in their software. Someone should explain to them that Overpass API can take care of this in a trivial way. (fr) (automatic translation)
  • On Mastodon, Erwin Olario points to a discussion on the OSM Asia telegram channel about a Corporate Editing Heatmap (source code). The tool was created by Jennings Anderson. It shows the areas where commercial, organised mappers are active. The results can be filtered by year and company.

Community

  • Simon Poole is surprised that there are more mappers active in OSM in the United States on weekdays than on weekends. Are there more commercial than independent mappers? See the charts at osmstats.neis-one.org for reference.
  • François Lacombe reports (fr) (automatic translation) about the OSM-France monthly project last July to import and survey the power grid (automatic translation) in France and what preparations were involved. The quality control tool Osmose played an important role in the process.
  • Tomasz_W described his experiment on changing the pastel shades of parks in OSM’s main map style Carto to darker colours.

OpenStreetMap Foundation

  • The Chilean company Altavoz now sponsors the first South American tile cache in the CDN (content delivery network) for tile.openstreetmap.org. (es) (automatic translation)

Humanitarian OSM

  • Hawa Adinani from Tanzania reports about the completed student training in Dar es Salaam, where 228 sub-wards were mapped to support disaster risk management projects and interventions to clean rivers and drains.
  • Nate Smith announces a new tool named MapCampaigner, developed by HOT. MapCampaigner’s developers describe it as a “data quality observation tool” intended to follow up on the work done by contributors performing local field surveys tracking specific tags. For example, a report on Botswana flags buildings with missing building:roof or building:levels tags.Critics on the mailing lists respond that this does not address more important data quality issues including those with building geometries, unlike other tools such as Osmose, OSMI, and KeepRight.
  • Reliefweb reported that the government of Niger partnered with the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR) to gather data on flood risks in Niamey, Niger’s capital. Data collected included high-resolution images gathered by drones and 15,000 data points, on households and infrastructure, collected with an open source mobile application by Niger’s OpenStreetMap community. The data was used to model the flood risk of the most vulnerable communities in Niamey.
  • With extensive mapping activity (1,2) taking place in the aftermath of the earthquake and tsunami which devastated Palu and other parts of the Indonesian island of Sulawesi, readers may be interested in an article in National Geographic about the science behind this event. The recent gathered OSM data has been used by UN damage assessments.

Maps

  • [1] User acsd has created an online Parking lanes viewer, which includes an easy-to-use editor.
  • ITO Map is currently having problems with maps that use OpenStreetMap as the base layer – some maps are completely out of service.
  • An interesting representation of the oceans is shown by Le Cartographe (fr) (automatic translation) in their blog.

switch2OSM

  • Belgian Railways created a map that shows the positions of their trains in real time on a properly attributed OpenStreetMap background.
  • SomeoneElse wrote a guide on how to switch2osm for Docker on CentOS in his user diary.

Software

  • Vincent Privat, one of the main JOSM developers, deplores how Oracle’s Java v11 keeps removing features that are crucial for JOSM.
  • Matplotlib, the data visualisation library for Python, announced the release of the version 3.0 with many new features.
  • Bryce Cogswell (OSM User bryceco), maintainer of the OpenStreetMap editor for Apple platforms GoMap!, announced that the code is now open source on Github.
  • Daniel writes a diary post announcing the release of RoboSat v1.1.0. Here’s what has changed since the last release: this release is powered by major community contributions ranging from features such as fine-tuning trained models to training and prediction speed-ups, and bug fixes! He also especially thanks to the contributors.
  • The quality assurance tool osmose has recently implemented checks for unconnected highways and crossing ways for highways and waterways.

Programming

  • Heidelberg University received funding for the development (de) (automatic translation) of an app called “meinGrün” (myGreen), that is intended to improve the public perception and information about public green spaces in urban areas.

Did you know …

  • Bexhill-OSM? It is a passion project that aims to help people discover information in and around the seaside town of Bexhill-on-Sea. Amongst other features, the map offers pedestrian routing and click-to-query-features.
  • ReMAPTCHA? As with every anti-spam mechanism it prevents automated programs (bots) from registering. In addition, the ReMAPTCHA challenge will help to correct unconnected ways in OSM’s data.

OSM in the media

  • The Swiss TV channel SRF broadcast a short documentary in German about the work done by the Missing Maps project to map remote villages in Africa on OSM and enrich the remotely mapped data by doing local surveys.
  • Steve Bernard, the design editor at the Financial Times, hosted an AMA on Reddit about cartography and data visualisation.
  • The Haitian OpenStreetMap community of Saint-Marc has asked (fr) (automatic translation) that city hall administration help them count buildings in their municipality. They have to map on a shoestring budget and are in need of funding.

Other “geo” things

  • Sasha tweeted that even Google’s website developers.google.com produced an error message when they exceeded the quota for their own maps API.
  • Bike sharing providers in larger cities are starting to move from Bicycle Dock parking to Dockless bicycle rental (88 cities in the USA with this kind of bike sharing). Bicycles integrate a GPS and a geolocation transmitter to a central station with the side effect of generating data on how they are used, which in turn results in cities being able to improve their bicycle infrastructure.
  • The Belgian Ministry of Defence wants to sue (de) (automatic translation) Google for refusing to blur sensitive areas on its aerial images.
  • In a tweet Anonymaps points to HERE’s xyz.here.com/studio/, which offers the upload, management and visualisation of geospatial data. The tweet can be read as a speculation that HERE will enter into competition with Mapbox studio.
  • Is your Map and Navigation app keeping track of your whereabouts and using it for commercial purposes? (automatic translation)
  • The local newspaper Böblinger Bote reports about the project Elevate of Berlin’s Sozialhelden user group, who also run wheelmap.org. The aim of the project is to provide wheelchair users with information such as the operating status of elevators, which is obviously crucial for them to know ahead of time. Real-time information from the Deutsche Bahn, the Stuttgart S-Bahn as well as the transport associations Berliner Verkehrsbetriebe, Region Rhein-Ruhr, and Hamburg will be integrated into Wheelmap.

Mapping

  • User 817817 explains in his blog (ja) why he’s mapping surveillance cameras, and he encourages others to map them too. 817817 says that mapping surveillance cameras contributes to both privacy and security and that it will trigger people to reconsider their own privacy. (automatic translation)
  • Thejesh GN wanted to print some maps with Marble in the Kannada language, which is spoken by 40 million people in southern India. He noticed that this language is underrepresented in OSM. He created instructions to fix that problem using iD.
  • Voting has started for highway=toll_gantry, proposed to be used on nodes to denote a transponder or camera gantries to toll bridges.
  • Daniele Santini prepared a proposal for the key assembly_point:purpose= to specify for which kind of hazard – fire, tsunami, earthquake, tornado – an emergency=assembly_point was created.
  • Joseph Eisenberg is proposing the key prominence= for peaks. While the established ele= provides the value for the height of the peak, the new key is intended to indicate how tall a peak is compared to the surrounding area.

Community

  • Frederik Ramm started a discussion on the dev mailing list about extending the range of possible user blocks and making them more granular. The questions raised might not be most appropriate for that mailing list.
  • The Wikibase extension (which we reported earlier), that is intended to store structured tag metadata, is now live. However, response to this promising change has been muted to date.
  • OpenSnowMap.org’s maintainer yvecai has compared the data at Skimap.org and the ski pistes in the OSM database. Neither project is complete so it is hard to estimate OSM completeness.
  • The organisation Potentiel3.0 wrote two tweets [1, 2 (fr)] about the QGIS and mobile data collection training for agricultural engineers at the University of Grande Anse in Jérémie, Haiti.
  • David Morais Ferreira (OSM dmlu) was chosen as mapper of the month by OSM Belgium.

OpenStreetMap Foundation

Events

  • [1] Mikel Maron tweeted how a cake should look like if it was made for mappers.
  • The INTERGEO fair, which will take place in Frankfurt from 16th to 18th October 2018, will also host the OSGeo-Park this year. OSGeo-Park informs visitors about Open Source GIS, free geodata, GIS technology, and OpenStreetMap. The organisers are still looking for a A0 printer to print maps on the fair. The program is still a work in progress.
  • HeiGit will present Openrouteservice.org at INTERGEO 2018 (Frankfurt, Germany 16th-18th October) in the booth of the German Federal Agency for Cartography and Geodesy.

Humanitarian OSM

  • Nicolas Chavent tweeted from Haiti about his preparation of his second OSM, open data and GIS training week.
  • HOT prepared a short analysis about the use of available imagery sources. It shows that the majority of HOT tasks use Microsoft’s Bing imagery.
  • RichRico wrote a post about the cooperation of Development Seed’s data team with HOT in the previous months and detailed the projects they were working on.

Education

  • In Haïti an 11 day workshop was organised from 17 till 28 of September. During the first 2 days participants were taught field surveying, JOSM, uMap, and QGIS for editing and rendering the data.

Maps

  • Klokan Technologies tweeted about the simplification of map creation with its MapTiler Cloud product. According to a blog post it is possible to design a personalised map with only five clicks.

switch2OSM

  • In Belem, Brazil, there is an annual religious parade that attracts two million people. The state IT agency Prodepa has created an OSM-based online map of the "Círio de Nazaré" procession including prominent contact points, specially set up medical stations and time restrictions on road closures.

Open Data

  • The Open Data Institute launched a fund to encourage local governments in the United Kingdom to release geospatial data as open data and to explore collaborative approaches to data collection, management and use by the Ordnance Survey, OpenStreetMap and other open data or civil society groups.

Software

  • The Suspect Lists of BRouter, that can help finding errors and inconsistencies in the road network, are now available worldwide.

Programming

  • Sascha Fendrich from Heidelberg University calculated the size of the OSM history data in terms of raw data as it would be represented in systems programming languages such as C and Rust and derives some interesting numbers in comparison to data structures in XML.

Releases

  • Daniel Koć, maintainer of OSM’s main map style, just announced the release of a new OpenStreetMap Carto stylesheet. The changes in version 4.15.0 include new colors for gastronomy objects, farmland and societal amenities, rendering implementation of man_made=wastewater_plant and man_made=water_works, new icons, missing country label fixes and many others.

Did you know …

  • …. Map Compare, which can also be used to show the different addressees of the OSM mapping. The example of Falkirk in Scotland shows that on OSM, what can be seen on the ground is shown as far as possible. A comparison of video and map are worth watching.
  • MapRoulette? There are always possibilities to improve the OSM data.
  • … the tool Who’s That? If you want to lookup the former name of a mapper or you have the former name and want to find out the current username, the tools will do the job.

OSM in the media

  • The Factor Daily wrote a comprehensive article about OSM. It covers OSM’s relation to Google, what market potential is estimated in the map industry, why companies switch to OSM and the relation to government bodies, the Indian, here in particular.

Other “geo” things

  • Locusmap tweeted a picture of its map app running on a Samsung Gear under Samsung’s proprietary smart watch operating system Tizen.
  • Emily Badger published an article with an interactive map in the New York Times about how connected locals in the US are on Facebook.
  • There is not much time left to take pictures for #WikiLovesMonuments 2018, the world’s biggest photo competition around cultural monuments.
  • COBI.Bike proposes hardware to interface with your bicycle or e-bike. The app for iPhone is described in this article (de) (automatic translation). It exists for Android too. It uses OSM data for navigation.
  • Linda (Hecht) Stevens wrote an article on medium.com about her view that the availability of geospatial data like imagery, base maps and localised information, fuel a GIS revolution that has yet produced new spatial analysing tools like for 3D rendering or data visualisation.
  • kerook.eu published an article about nice looking pouches with OpenStreetMap renderings printed on the fabric.
