Mapping


  • In a series of tweets, Tyler Busby talks about the success of using machine learning to identify solar panels on rooftops in Austin, Texas. These data formed the basis of one of the tasks of the MapRoulette project with the aim of their further addition to OSM.
  • Nuno Caldeira tweeted about the work done by the Portuguese OSM working group at Telegram. Over 35 days, its participants mapped more than 4,000 buildings on the islands of Flores and Corvo in the western part of the Azores archipelago.
  • Brian Prangle invited the OSM community in the UK to focus on improving the quality of POI data in the second quarter of this year. He believes that in the first place it is worth paying attention to those organizations that have ceased to exist or have changed their name. It is worth noting that in the first quarter in the UK, a project was successfully implemented, in which more than 70 thousand addresses were clarified or confirmed using the rating of the Food Standards Agency.
  • Dan S proposes to mark solar panels on a map as a project for the UK. He also provides links to OSM wiki articles on solar panels on rooftops and large solar farms . The information in these articles can help in solving the problem proposed by him.

  • User JM82 is surprised(de) (automatic Google translation from German) that the number of mapped buildings in Austria seems to be decreasing.
  • Member Klepper from Colombia invites all active osmerias to help him map the Choco area ( task number 121 ). This territory has always attracted migrants from different regions, but recently there have been significantly more of them due to the political crisis in Venezuela.
  • The German OSM Forum is now actively discussing(de) intensive mapping of access roads in residential areas, which was carried out by employees of various publishers. User boldtrn notes that on his street this was done with errors (from 30 to 50%).
  • Loretzno Stucci proposed three new tags for the landcover tag. It offers areas that are cultivated by people, such as farmland or meadows, to celebrate landcover=cultivated. The areas changed as a result of construction, mining or other human activities, map how landcover=artificial, and spaces without vegetation, where there is only bare soil, - landcover=barren. Discussion of his proposal has been going on since April 6, 2019.
  • CapitaineMoustache offers places to store crops (areas where silos and barns are located) to celebrate as a couple industrial=grain_storage_centre. The discussion began on April 5, 2019.
  • Britain's national mapping agency «Ordnance Survey» published on Twitter a photo of geodetic works, which they have started at the new stadium, "Tottenham Hotspur". Despite the fact that the stadium opened in early April, it, as Steve Chilton notes , has already been rendered in detail in OSM.

Education



Cards


  • Russ Garrett improves on the OpenInfraMap map : different types of infrastructure are now displayed as separate layers, and a layer with a heat map of solar panels has been added.

Programming


  • The research team at Heidelberg University GIScience released the announcement of a new Openrouteservice client for mobile devices.

Programs



Do you know …


  • ... about the comparemaps.drona.ro tool that allows you to compare OSM maps with Google, Bing and Nokia Maps?
  • ... about the KartaGPS app ?
  • ... that there was ObzorZametok ( NotesReview ), which you can use to search among OSM notes using different search terms?
  • ... about Pic4Review ? It allows you to map, use Mapillary images, and participate in various missions, such as adding wheelchair access, adding eco points, or integrating missions into public toilets. You can also add your own quests!
  • ... about the concept of an "advanced stop line" for cyclists? This marking allows bicycles to wait at a traffic light ahead of other traffic participants. In OSM, they can be tagged cycleway=asl.

Other “geo” events


  • Vultures began to avoid Portugal. As it turned out, this was influenced by legislation that forces Portuguese farmers to bury or burn carcasses of cattle.
  • Many economists believe that the success of large cities, when compared with small ones, is due to the so-called "Agglomeration effect." Tom Force of ODI Leeds, in his article on CityMetrics, proves that this statement does not apply to Birmingham, as public transport is poorly organized.
  • Simon Küstenmacher on Twitter shared a link to an article by the World Economic Forum, which shows maps of five wild places in the world.
  • Mike Blackmore (Mike Blackmore) posted on Twitter an animation that shows how there is a "development" of European rivers, or rather their gradual straightening. Tweet William du Ploi no less shocking: it shows how much of the forest was cut down in Mozambique over the past 19 years.

Community


  • Colin Blackburn is intrigued by the name of the beach at OSM's “Optional Clothing” along the route he planned to run. We hope that he will not use Mapillary at this time.
  • In his diary, a member of hvalentim wrote (automatic translation ) some thoughts on mapping national registered Portuguese heritage sites in OSM: some gaps were discovered and many other suggestions were made to improve and standardize tagging.

Imports


  • Jason Owen developed a plan to import water wells in Harare, Zimbabwe, and announced this on the import mailing list.

Events


  • The reports are now open for the HOT Summit 2019 conference, which will be held September 19-20, 2019 immediately before the 2019 SotM in Heidelberg,.
  • Registration for the SotM France conference is open, which will be held in Montpellier from June 14 to June 16, 2019! (fr)(automatic translation )

Humanitarian OSM


  • HOT has made the salary process transparent for its employees. Despite the fact that the salary of everyone was not disclosed, the formula and methodology by which it is calculated are now available to everyone. On this occasion, the HOT team prepared an article in which it explained in detail why they were concerned about the transparency of payroll and what difficulties they encountered when they tried to find a fairer payroll model. In addition, the material reveals how exactly the new model eliminated the pre-existing inequality and how its implementation affected the size of wages.
  • The stage of nominating candidates for the HOT America team has begun, which will last until April 16, 2019. According to Natalie Sidibe on the mailing list, this year HOT will allow self-nomination to increase the number of candidates.
  • Gaurav Thapa from Kathmandu Living Labs shared how geospatial data were collected in the Kathmandu Valley (Nepal) as part of a project that explores natural disasters to reduce damage from them.
  • Jorieke Vyncke, on behalf of the non-profit organization Doctors Without Borders, thanked the HOT team for their work in helping to manage the effects of the Idai Cyclone in Africa.
