OSMLatam’s and GeoChicas’ mapathon for OSM’s 13th Anniversary 1

About us

  • We are always looking for people to help us improve our newsletter so it can get out faster, have more depth and coverage, and generally improve it for our readers, like you. Please join our team by contacting us now, its fun! 😉

Mapping

  • Pascal Neis tweeted a graph showing “Average OpenStreetMap activities per hour”. It shows a world of “lunchtime mappers” – the drop between 6 & 7am CET is an artifact of data processing, but peaks corresponding to (roughly) CET, GMT, Eastern and Pacific time zones can be seen.
  • Lukas Sommer improved his Language Information proposal which he argues should improve map rendering.
  • Thomas Bertels asked the Tagging mailing list how brasseries should be tagged. Discussion ensued.
  • François Lacombe cleaned-up the proposal for Fire Hydrant Extensions and other improvements follow.
  • Daniel Koć wants to improve the rendering of rivers but finds their classification lacking. Discussion in the Tagging mailing list.
  • On the Tagging mailing list, several people discussed how a shop selling solar equipment might be tagged.
  • User ChristianA wrote a blog post about his visit to the ruins of Schloss Dwasidien (de) on Rügen island, Germany.
  • Skinfaxi asked in the German OSM Forum as a representative of the Swedish community about what tagging is best for natural beaches at lakes, as there they just about everywhere in Sweden.
  • Jay May made an appeal to the whole OpenStreetMap community to help the Eastern Latvia (Latgalia), and Western Russia regions in improving the poor detail and accuracy of their maps.
  • Cesare Gerbino introduced his “Street Image Compare” which he created, where you can compare in a single screen Mapillary with Google Streetview.

Community

  • Pascal Neis shows in a bar chart, which groups of users on OSM are most commonly represented (number of users). Find your own classification on hdyc.neis-one.org.
  • Rodrigo Mariano prompts the Historic and Imports the mailing lists on the “Possibility to build a new Historic Project to OSM” hoping for integration into the Pauliceia’s project. Replies on Historic.
  • The DWG unfortunately had to remove over 10,000 place and street names in Switzerland from OSM because they were copied from the noncompatible GWR database. The French-speaking area of the country was particularly hard hit.
  • “Living, Breathing Maps” is an interview with Dale Kunce the GIS Team Lead for the American Red Cross about Humanitarian mapping and OpenStreetMap in general.
  • MikeN summarises his experience using MapRoulette to add missing railway=level_crossing tags in the United States. After 10 long months, the task is finally complete.

Imports

  • Jonah Adkins makes the first steps to import 19,000 buildings in Dare County, North Carolina. GitHub and wiki pages are available for comment.

OpenStreetMap Foundation

  • OSM Foundation’s Operations Working Group (OWG) issued a statement: “We unanimously agreed new membership policies for the Operations Working Group and the Sysadmins. We hope that these will help anyone who wants to volunteer by making the joining process, and the expected activities, more clear.”

Events

  • State Of The Map 2017 is set to take place starting Friday the 18th August (soon!) in Aizu-Wakamatsu, Japan.
  • Planning to be at the State of the Map happening in Japan? Don’t forget to add your details on the attendees’ page and connect with other attendees.
  • Crowd2Map wants to celebrate OSM’s 13th birthday on August 13th and 14th with the largest mapathon ever. They expect over 1500 people within 24 hours to map rural regions of Tanzania. The organizers have created tasks in the OSM tasking Manager and Janet Chapman wrote a detailed guide for the mapathon.
  • The Swiss OSM Association will hold a workshop at DINAcon. “We will show how to use OpenStreetMap to create a location map and how to tell stories with a map.”
  • FOSS4G Boston 2017 is coming up next week, from Monday, August 14th, to Saturday, August 19th. Check the program.
  • [1] To mark the 13th Anniversary of OpenStreetMap, in August 2017, OSMLatam together with GeoChicas are organizing a massive mapathon with national communities of the region. The objective is to map informal settlements.

Humanitarian OSM

  • From August 1st-4th, representatives of HOT Indonesia attended an expert meeting at Udon Thani to combat poverty in rural areas of Thailand. Special appreciation was given to the improved possibilities of building the infrastructure using OSM, responding to catastrophes, and working together with HOT groups, such as young people or other organizations.

Maps

  • The International Space Station has always at least one astronaut or cosmonaut on board who has an amateur radio licence. They operate the ISS amateur radio station ARISS. The Italian amateur radio operator and OSMer Fabrizio Carrai created a map which is linked to the Vita mission page of the planned contacts between ISS and schools in Italy, England, USA, South Africa and the Boy Scout camp in Großzerlang, Germany.
  • Rising Seas, an interactive map based on OSM displays the history for sea level in 500 places worldwide from 1970 until today.

Open Data

  • The slides of the recent FOSS4G Europe in Paris are now online.

Licences

  • Following on from this OSMF blog post about the lack of compatibility between CC-BY 4.0 and ODBL, www.europeandataportal.eu has added some confusion by listing ODBL 1.0 as a licence compatible with CC-BY 4.0. This was raised on the “talk” mailing list, with Simon Poole from the Licensing Working Group replying there.
  • Simon Poole on behalf of “the LWG would like to start a period of public review and consultation on our draft trademark policy”. A lenghty discussion follows.

About us

  • We are always looking for people to help us improve our newsletter in anyway they can. Please join our team 😉

Mapping

  • Pascal Neis tweets about a large number of new buildings around Surabaya, Indonesia, without any kind of highways or paths leading to them. On the discussion, other people point other places with the same issue and Pierre Béland discovers that the changeset comment and source are wrong.
  • John Whelan asks if recent changes of the Highway Tag Africa wiki page can be highlighted. The revisions were agreed during a workshop at SotM-Africa. Discussion follows about the modifications made vs the goal of this wiki page for the highway tag to take account of the socio-economic role while other keys take care of the condition and practicability of the road.
  • Christoph Hormann starts a discussion about the decline in accuracy of capture date metadata in Bing imagery, remarking that a range like 2003-2016 seen in a rural area is pretty useless for the purpose of mapping.
  • François Lacombe asks on the Tagging mailing list for comments on his proposal to add extra details about power transformers devices functionalities and specifications under the transformer=* tag.
  • Tobias Zwick wants to add a quest to his StreetComplete app to specify the produce of orchards. Currently three tags are used so he asks for comments on how to implement the tagging scheme.
  • Christoph Hormann blogs about the problems of mapping without recent on-the-ground knowledge, otherwise known as remote or arm chair mapping. The different dimensions of image quality are discussed and exemplified by its age the main culprit.
  • Polyglot wonders why so many details are repeated across OSM objects when mapping public transport and why we need 2 objects for each stop in every route relation, given that this makes maintenance harder. Several people reply with comments.

Community

  • Pascal Neis tweets how the different levels of the OSM activity are attributed on his HDYC tool (How Did You Contribute to OSM?)
  • Mutual Learning: In their July issue of the monthly "showcase", the Wikimedia Foundation’s Research Team discussed OSM data structure and further cooperation models. The live stream has been published on YouTube.
  • In the German forum there is a wide-ranging discussion of "what OSM mappers map and why" has changed in the last 9 years (automatic translation). Two participants of the discussions claim that the thread is collection of people whose ideas did not gain wide enough acceptance by the community.
  • Voting for the 2017 OSM Awards has started, and will end on August 16th. There are 45 nominees in 9 categories to choose from.
  • User GoWin blogged about his visit to the General Santos City firefighters and the impromptu mapping activity he had with them completing the layout of their fire hydrant network.

Events

Humanitarian OSM

  • Marco asks on the HOT mailing list how to map paths and roads through rural villages in Africa to assure routing. The interpretation of the imagery and how to map his example (Mula village, north Nigeria) are discussed in the replies. He also asks about creating virtual highways within residential areas. In the context of semi-desertic areas with no infrastructure and only traces in the sand, there was also discussion with divergent "do not connect" and "do connect" opinions.

Education

  • Christian Quest wrote an easy to understand article about geocoding. (fr) (automatic translation)

Maps

  • [1] OpenStreetBrowser (OSB) is once again online. Now you can easily search for POIs. The website shows a narrow menu on the left side, similar to common Wikis and the main page of OpenStreetMap.org although not static one. 20 languages are available.
  • RandoCarto provides customised hiking maps.
  • shtosm.ru explains (ru) (automatic translation) why users of OpenStreetMap.org from Russia and Belaurus experienced slowly loading map tiles a few days ago. It was caused by scraping the tile cache sponsored by Yandex.

Licences

  • The OSMF publishes a template waiver/permission for the use of aerial imagery in tracing.

Software

  • Bryan Housel mentions in a longer comment that "JOSM-style validation" is coming to the iD editor.

Programming

  • On Medium.com, David Hayter details how a PostgreSQL database might be hacked without user account on the target system if not properly configured.
  • Vladimir Agafonkin of Mapbox blogs about the making of his wind power simulation map using WebGL.

Releases

Did you know …

  • Who’s That by Ilya Zverv, that tracks the renaming of OSM users accounts and makes them searchable.

Other “geo” things

  • Anthony Bennett tweets a nice video from 2016 "What if everyone lived in just one city?". With its density ranging from a sparsely populated city to the most crowded place in history, how big would it be?
  • Mystery structure on a South China Sea reef. It’s not visible on OSM but is there someone interested in a survey? 😉
  • The longest pedestrian suspension bridge of the world was opened on July 29th. With a total length of 494 meters, it connects the villages of Zermatt and Grächen in Switzerland.
  • Don’t Panic Labs published a thorough step-by-step tutorial on how to use Mapbox Studio to create a heatmap of your workout activities.
