YouthMappers Pre-conference meeting.

On the 18th August YouthMappers called its members to meet. This was a great moment ever for YouthMappers member to meet again for second conference since 2017. This gathering was the combination of the 2020 research fellows, regional ambassadors, YouthMappers technical supporters, director, communication officer and the board members.

The first meeting created a space for YouthMappers members to be updated, knowing one another, interacted, collaborated and above discussed the major impacts in their communities as a collective. In the process of continuity in the building of young people who define their future through community works and actively engaged in identifying problems and offering solutions, YouthMappers awarded certificates of appreciation to all its young people. This was a great motivation to Youths who tirelessly and selflessly contribute to open sources.

Highlights:

In 2022 during the conference YouthMappers @[youthmappers.org] launched the first ever documentary in history, highlighting the major impact and voices of young people inclusively. Additionally, in recognizing the efforts of young people across the #67 countries with #327 YouthMappers chapters, young people combined their voices and released the book around all sustainable development goals. This book is a true reflection of YouthMappers current, Alumni, technical team and board of directors voices. It has showcased some major impacts, works and efforts of the young people in their different communities.

  • Mapping
    • Keep up the regular mapping around the place, and while at SotM
    • I wish people would stop adding new man_made tags. #
  • I posted about my State of the Map 2022, which used up most of my mental OSM energy for August.
  • OSMF Board
    • Some suggestions for SotM 2023 generated some board ⇄ sotm wg emails. (I tried to do the right thing and CC the right people while communicating. This policy was adopted by the Board last year. The board member who claimed the board supported the CM bid didn’t tell the rest of the board of this).
    • Local Chapters
      • At SotM, apparently 2 groups asked a fellow board member about becoming a local chapter for Nigeria & Eritrea.
      • I got their contact details and started reaching out to them to start the process
    • Board Meeting
      • I attended the Aug 2022 Board meeting
        • I did plan to schedule an AB meeting with corp. memb.
      • also attended the Aug 2022 mid month chat, there was discussion about
        • odbl-only imports
        • prep for SotM 2022 (osmf stand, board AMA)
        • whether monthly reports from pers. comm. were needed (probably not)

(sorry if i’m missing some details, I’m trying to finish this)

This is a plan for the addition of building footprint data for Tanga City, Tanzania. The import is currently going through the Import Guidelines steps, and it should be soon an ongoing crowdsourced task

The goal is to import building footprint data developed by Ardhi University (ARU) in Collaboration with Tanzania Communication Regulatory Authority (TCRA) in 2021, using 2019 satellite images.

Read more at : osm.wiki/Tanga_Building_Footprints_Import

Promoting a data-driven decision making culture in Tanga under living lab initiative, we are complementing the global objective of OSM i.e. to create a free editable geographic database of the world by various mapping activities around the region. The initiative uses local member by building capacity on how to use OSM and contributing to it as well as University Students. These mappings have been putting the missing pieces of the community on the map and addressing challenges they face so far. The usage of GIS data as a tool for community as a decision-making data tool can help in timely action and on-time problem-solving.

This is an Initiative for scaling up the OpenStreetMap Project by addition of buildings footprint data for entire region of Tanga,Datasets was developed by Ardhi University Students (ARU) in Collaboration with Tanzania Communication Regulatory Authority (TCRA) in 2021. Furthermore, There are different community mapping activities as micro-works going on in the region, as the mission of enriching and making freely global spatial data as well as capacity building to the local community on how to use free and open source tools in contributing data to OSM.

The current usage of tags in OSM for junctions between motorways is really dangerous in high density areas.

  • There is currently a tag for the junction that is put at the point where the driver can’t change anymore way but at great risk.
  • Author of the current situation say that it’s fine as there is some tags on main lane say there is a junction and mode lane during the split of main road and junction.

I tried it around Paris with Organic Maps in navigation mode. An oral announce is made few hundred meters that driver should at left or right in few hundred meters, then when the change is no more possible, that the change should be made.

In high density areas, junctions can be on the left or on the right, two or three exits can follow from few tens of meters, making it more confusing, especially if there in not any announce of the name or number of the exit (as in case of Organics Maps), and on often overloaded traffic in these areas.

A good solution could be the announce of the exit direction, number or road name/number to follow, that could be verified on traffic signs, this imply that traffic signs nodes contains these informations. In France, on A6, exit numbers are given (ref field), but not the exit direction/name (name field).

Around Ris-Orangis in about 1000m (~40s at 90km/h) there are lot of changes at left/right between A6a, a6b and A10 The current representation doesn’t display at all the parallel lanes, but only start at the last moment the change can be done, from few tens of meters to several km after the start.

The driving rules, say to go as soon as possible on the exit and THEN to slow down quickly, not to slow down on the main lane, nor to wait for last time to change to exit lane.

Warning: you read this at your own risk and you may collide with a wall of text. I’m sorry, but it didn’t fit in a few words.

I listened with interest to Florian’s speech at SotM 2022 (https://youtu.be/BRv-IFp_zZs), unlike him I do not feel I am a long-time contributor, although I consider myself active, both in terms of OSM editing and my activities in the Polish OpenStreetMap community. I would like to add my voice to the discussion and support Florian’s position a bit.

Let me start with why, in my opinion, the replacement of the current OpenStreetMap operating model, both in terms of the organisation and the database, is necessary. The reasons are the threats and challenges that are becoming more and more apparent and, paradoxically, stem from the growing interest in OpenStreetMap and its development.

By way of introduction, I refer you to Jennings Anderson’s speech at SotM from 2020: https://youtu.be/BI0VrPyAtcQ

and the update he made a year later and published in his diary: osm.org/user/Jennings%20Anderson/diary/396271

I’ll start with the scaremongering - here’s a list of the threats I think we will face in the near future:

Threat One - loss of community control over the project.

Still influenced by my proposal for settlement_type=crannog, I’ve looked at how historic settlements are mapped on OSM. There are three more or less “right” ways to do it (and so many wrong ones…). The three options are * map as historic= [whatever type of settlement] * map as historic=archaeological_site + site_type= [whatever type of settlement] * map as historic=archaeological_site + site_type=settlement + settlement_type= [whatever type of settlement]

The distribution today1 was (in reversed order from above, sorry):

settlement type/ form settlement_type=* site_type=* historic=*
ringfort 131 2 0
crannog 82 0 2
hut_circle 24 348 1
oppidum 8 15 3
city 6 612 16+(messy mapping) 2
village 3 11 58+ (messy mapping3)
town 2 0 12 (+ 3 “ghost_town”)
longphort 1 0 0
rundling 1 0 0
hut_site 1 0 0
hut 0 0 12
vicus 0 24 0
shieling 0 0 20 371
settlement n/a 3 788 ~25

In my opinion, historic= [whatever type of settlement] should only be used when the remains are still recognizable as buildings, like a ghost town or some sort of preserved settlement used as a museum (or “visitor experience”, as they’re now known), like some of the Pioneer towns in America.

Everything else I would classify as an historic=archaeological_site, and I personally would like to be able to classify settlements as such and then use sub-classification, if they are known. The high number of site_type=settlement supports that in my opinion.5

Moved to Munich in 2011, and not doing much mapping since… For Belgium I was “in here early” and starting on like a white sheet of paper. All biketours were openstreetmap-wise “new roads” and good for endles mapping entries, in Germany at that time “most seemed done”. Trying to add changes when I see them (new roundabouts, new roads, new maxspeeds) but often they are already taken care off.

Following the discussion over my proposal for settlement_type=crannog, I have done some clean-ups in the Historical group. Dear me, it was needed.

Today, I tackled site_type on taginfo which comprised of 38 messy pages. I spent 3.5hours

  • fixing spelling mistakes
  • changing upper case to lower case
  • changing spaces to underscores
  • translating values from a myriad of languages into English etc
  • translating and fixing values for historic:civilization
  • moving values from site_type to description or name
  • etc.

I’ve spent a few evenings and spare hours this week dusting off and updating osmdiff. If you’re a python developer and you need to interact with replication diffs or augmented diffs, this may just be something of interest to you. osmdiff can retrieve replication diffs as well as augmented diffs from OSM servers, and parse them into native Python Node, Way and Relation objects you can use in your code. This lets you do things like

>>> from osmdiff import OSMChange
>>> o = OSMChange()
>>> o.frequency = "minute"  # the default
>>> o.get_state()  # retrieve current sequence ID
>>> o.sequence_number
2704451
>>> o.retrieve()  # retrieve from API
>>> o
OSMChange (677 created, 204 modified, 14 deleted)

Once you have the data, you can filter and inspect it:

>>> w = [n["new"] for n in a.modify if n["new"].attribs["id"] == "452218081"]
>>> w
[Way 452218081 (10 nodes)]
>>> w[0]
Way 452218081 (10 nodes)
>>> w[0].tags
{'highway': 'residential'}
>>> w[0].attribs
{'id': '452218081', 'version': '2', 'timestamp': '2017-11-10T13:52:01Z', 'changeset': '53667190', 'uid': '2352517', 'user': 'carths81'}
>>> w[0].attribs
{'id': '452218081', 'version': '2', 'timestamp': '2017-11-10T13:52:01Z', 'changeset': '53667190', 'uid': '2352517', 'user': 'carths81'}
>>> w[0].bounds
['12.8932677', '43.3575917', '12.8948117', '43.3585947']

You can also use osmdiffs implementation of Node, Way and Relation objects separately if you need just those, the library is quite small and has few dependencies (just requests and dateutil)

On the list of things in development and slated for the next release are: * Python __geo_interface__ support so you can easily use them in other Python modules that support them like shapely and geojson * Retrieving individual OSM features from the OSM API * Ability to create an AugmentedDiff / OSMChange object with a datetime parameter, which will then calculate the sequence number for you * More tests, always more tests, and CircleCI integration

Recently I introduced a few “OpenStreetMap Quality Control” categories:

  • Fix Me - All map features which have a “fixme” (or similar) tag, categorized by suffix (e.g. fixme:name) or content (e.g. “name wrong”). It can also filtered by type of feature (e.g. Shop, Road, …).
  • Culture - Media/Wikidata - In my opinion, each cultural map feature (artwork, memorial, tourist attraction, …) should have an image and/or a wikimedia_commons category (red=missing, light blue=set). Often, there even exists a Wikidata item (dark blue). Many memorials erroneously have the wikidata link to a person (magenta), this should most likely be a “subject:wikidata” (resp. “subject:wikipedia”) tag.
  • Wikipedia - This category was in the “Special” top category before. It shows all map features in the area with a wikipedia or wikidata tag (including prefixes, e.g. “subject:wikipedia” or “name:etymology:wikidata”).

2022 Board elections are coming up for OSMF. You can see what the details will be like on the wiki page from last year. There are three seats up for election, not clear yet who from current Board members will run again.

We need people to run who are focused on specific needs, and ready to put in professional level work on a volunteer basis. In other words, folks who can pick a 1 or 2 things, do good work on them, in service to our community. There are plenty of chunky problems that need ownership.

Me, I’ve been on the OSMF Board longer than anyone. I used to try to cover everything. Now my work in OSMF is very focused on 2 areas – personnel and fundraising. We need to look after our people and make OSMF a good place to work. And we need resources to make our plans happen. It’s a lot, but I’m limiting my time to these.

There’s a lot of noise and energy around any election, and that holds pretty true for OSMF. It’s the one time of year many think about the OSMF at all. But the real work happens in the rest of the year. Very little of the campaign manifestos really matter. Opinions and positions don’t really matter. Through strategic discussion, we largely agree on what needs to get done. Doing the work is what counts, and that’s what we need in Board candidates.

Jumping directly into the OSMF Board with no prior OSMF experience is hard. There’s lots to do on Working Groups and Committees throughout the year. Helps build reputation across our global community, and familiarity with how we function.

That said, whatever your experience, if you are ready to jump and put in the work, I’d love to support you. Reach out and we can talk. I can share my insights on the process and what it takes.
