In my first post, I want to share with you how I got back to running after the break.

Posted by Samrich1 on 3 March 2021 in English (English).

Practice walking before starting to run again. Before returning to running, you must be able to walk for at least 45 minutes (no pain when returning from injury). Walking restores soft tissues (muscles, tendons, ligaments, fascia, connective tissues), preparing them for more serious stress.

If you are taking a break due to an injury, consult your doctor before returning to running.

Exercise a little, but regularly. After a long break, it can be difficult to get back to your regular running rhythm. But it’s more important to focus on consistency at first.

Fixing municipalities without townhall

Posted by Cascafico on 3 March 2021 in Italian (Italiano).

Required:
* Public Administration (PA) offices dataset
* Openrefine tool

  • Create Openrefine project from PA offices dataset. Filter as needed (ie: titolo_resp=”Sindaco” and Regione=Abruzzo)

  • Generate Abruzzo municipaities without townhall with overpass-turbo query;
  • find the link of “Exporting raw data directly from Overpass API”;
  • copy&paste link in Openrefine Create project Web Addresses (URLs);
  • apply cross table funtions as needed (ie: cell.cross(“Indice PA”, “Comune”)[0].cells[“Cap”].value
  • Openrefine custom tabular export the file somewhere online;
  • feed above file to umap remote data with useful tags displyed in popup (layer interaction)

Here you can find the resulting umap, used for add and detail missing municipality townhalls.

At least one edit a day

Posted by Rabin Ojha on 2 March 2021 in English (English).

In 2020, I made at least one edit a day for 332 days. You can see the screenshot of my HDYC profile on March 2, 2021. During the year, I mostly mapped buildings, roads, and landuse around Nepal and Afghanistan.

I have an ambitious goal of making at least one edit per day in 2021. Let’s see how far can I go!!

A rare example where two Geoglyph lines resembling a right angle.

Posted by c tito young on 2 March 2021 in English (English).

These two Geoglyph lines 80m x 50m are just a few fractions of a degree from a right angle. One thing rarely seen out here are right angles and this one, even though not perfect is pretty close. These two line proves to be obtuse in geometry, than a perfect 90 degrees.

There are two other lines that resemble the letter V. This land is fairly flat.

I have some key questions regarding the lack of 90 degrees and while I brought it up before, it really begs the question why is it so rarely seen here? Objects tend to point north, or magnetic north.. also they likely line up with constellations. Unlike any other earlier cultures, at least in terms of Geoglyph lines, right angles, 45 degrees, 30 degrees.. are rarely ever seen. Why? If you think about it.. any alien worth his two cents in being able to do interstellar travel, would likely have those all over, even like they do with crop circles. Speaking of circles, those are also a shape never seen on these these lands… why?

What I've Been Doing, What I'm Doing Next

Posted by salisburymistake on 2 March 2021 in English (English).

Bing Aerial Refresh

In fall of last year the Bing aerial imagery of Springfield, IL was refreshed, finally fixing a huge north/south tear down the middle of the city that had made adding accurate geometry within it nearly impossible. The new imagery is from that summer and is absolutely fantastic. It even covers outlying towns like Chatham, Rochester, Riverton, and Spaulding. I’ve been hard at work fixing alignment problems and adding new roads and buildings that I had heard about but hadn’t had a chance to survey. This and the pandemic are largely responsible for taking me over 270 mapping days last year, a personal best.

Accessibility

I’m not really hardcore about adding individual parking spaces, but when I saw the iD preset for accessible parking spaces I knew it was something I could and should add whenever possible. As a result, over 5,400 accessible parking spaces in the Springfield metro area are now mapped, accounting for more than half of those mapped in the United States as of this post.

I’ve been pretty good about denoting accessible crosswalks, even those with tactile pavement, but I definitely need to do another pass through some neighborhoods now that the imagery has been updated. The city does have a rather robust sidewalk/crosswalk improvement program and there are probably dozens of walkways that have been upgraded since I last mapped them all. Additionally, I’d like to be more fastidious about adding entrances to buildings/businesses so that distances can be determined between them and their associated accessible parking spaces.

Roadway Detail

For the longest time I was hesitant to delve into adding lane information for segments of roads, because… well, I just didn’t like the idea of splitting roads into a bunch of different segments. I thought it would make it more tedious to update speed limits and things like that going forward.

Well, last year I finally took plunge and I estimate Springfield is at least 95% complete in that regard. Does it make things more tedious to add more detail later? I’ve been adding snowplowing info for our emergency snow routes recently and yeah, it’s a bit tedious, but at a certain point you just need to accept that more detail is going to require more work, that it’s not going to be a convenient couple of clicks. Only makes the sense of accomplishment more pronounced, if you ask me.

I’m not saying everyone should start doing this immediately. But once you feel comfortable, when you’re doing your umpteenth pass over your local area and wondering what more you can add, it’s an interesting project to take on. You’ll learn a lot about your city.

Cycling

I’m no cyclist, but I recently picked up an escooter for quick trips to the store and to commute to work, and since there’s some overlap in regards to infrastructure and amenities, I’ve been plugging away at updating what I can. Bike paths and lanes were already more or less squared away before I came along, but amenities like racks or stands, not so much. But now I can say that OSM is the most accurate source of that information for Springfield than any other. That isn’t to say it’s complete, mind you! Just that I’ve cataloged enough to surpass the “official” maps of cycling amenities available from the city and local cycling groups.

I see this taking me down an entirely new rabbit hole. The cycling infrastructure in Springfield is severely lacking and when I commute to work I find myself opting to take my scooter down alleys in hopes of minimizing interaction with vehicle traffic. I did a substantial amount of planning before attempting my first commute on the scooter and I thought I had determined the perfect route, but it turns out vehicle traffic doesn’t hold a candle to the real enemies: smoothness and incline. I had seen those tags before but did not fully appreciate what they represented until I had to deal with them. There are some astoundingly wretched alleyways around here and they absolutely need those tags added to them.

Smoothness seems straightforward (though a bit subjective) but incline I’ll have to do some digging on to figure out how to record properly. If anyone knows of tools/gadgets to get the job done, let me know. I’m willing to spend some money on it.

Public Transit

As the transit planner at SMTD you’d think I’d be all over this, but - and I think I said this in a previous entry - my personal opinion is that if there’s an existing GTFS feed for a transit agency in an area then they shouldn’t be mapped in OSM, and OSM-based apps should instead pull from those feeds. It’s cleaner and more timely than relying on some random user to update OSM to reflect changes to routes. Not to mention, OSM will never be able to do what GTFS-realtime does, for obvious reasons.

That said, I did stumble upon this project that facilitates the synchronization of transit stops between GTFS and OSM and it looks promising. I love the idea of being able to upload our stops directly to OSM and being able to get subsequent additional info via OSM edits that we can then pull back into our data. I see the utility in that and if anything I’d like to up the ante: do the same for the rest of the GTFS feed. If I could fully replicate/sync our static GTFS in OSM via an automated/batch process I would integrate it into my workflow in a heartbeat.

Odds & Ends

Let’s see… another thing I’ve been getting into is denoting lamp_mount for highway=street_lamp. Downtown Springfield has a curious mix of bent_mast and a much smaller straight_mast and I was curious to see the distribution. I’ve kinda just been updating these as I go along. Once it gets to the point where I’m rarely running into lamp_mount tags I’ll run an Overpass query to find the stragglers and I knock them out but I have a feeling it’s going to be awhile; I’ve added over 15,000 of them.

Geoglyphs of the hairpin turns.

Posted by c tito young on 2 March 2021 in English (English).

In an area of about 600m long and 400m wide, hairpin geoglyphs mark the landscape with manmade tracings. Multiple lines possibly added up over 10,000m of lines characterize this landscape. The lines move from NE to SW and all appears to have curves. Erosion has erased some of the hairpins and possibly details.
To the north of the site, is a large 110m x 100m viewing / gathering area atop a hill and surround by a natural protection on the southern western side. The entire site except for the viewing areas appear rather flat with a gentle slope.

Geoglyph of an elongated head.

Posted by c tito young on 2 March 2021 in English (English).

A suggestion geoglyph of an elongated head 25m wide by 50m long, oriented north to south on a change of elevation of 10m shows an abstract elongated head with two eyes, two nostrils and mouth.

The head may or may not be adjacent to a very unrecognizable geoglyph located on its lower right side. This figure also has suggestions of a second elongated head but difficult to make out. There are some geoglyph lines suggested indicated as framing the elongated in that area. .

Mapping Parklets in Seattle

Posted by Stephanie May on 1 March 2021 in English (English).

Outdoor seating has become more important than ever in times of pandemic - but I noticed recently that places that people can sit and drink a coffee or read a book on a bench or at a table are not mapped in my neighborhood in Seattle. Lots of restaurants have co-opted sidewalks and even parking spaces (this would have been very controversial a year ago!) for use by their customers, but I’m more interested in street seating that can be used by anyone.

Everything I’ve mapped so far falls under the category of “Parklet” - it’s a permitted structure usually built by, but not exclusively for, nearby businesses. There are some charming ones around town, see pics here and here!

I noticed today there is a tag leisure=parklet, used infrequently and almost exclusively in San Francisco. Instead I’ve been using leisure=outdoor_seating in combination with access=yes, as this seems to capture identical information, albeit without reference to the parklet movement. So far I’ve only found one of the places digitized as something else - the parklet outside Cortona Cafe is tagged leisure=park. This is misleading, it’s a seating area between the sidewalk and the asphalt. Here it is on the website of a local political candidate

So far I’ve been capturing these as points, mostly out of laziness, but I should go back and digitize the tiny polygons, or if there is a polygon, remove tags like leisure=park. I’m undecided as to whether I should tag them as both leisure=parklet AND leisure=outdoor_seating at that point?

I’m also not naming these parklets, as most are referred to either with the name of the sponsoring cafe, or the nearby intersection, and I don’t know that need this info, except maybe for Nominatum?

Please feel free to weigh in on this endeavor :-).

Summary Maps of OSMF 2021 Survey Results (Part 2)

Posted by migurski on 26 February 2021 in English (English).

This post is a followup to yesterday’s maps of OSMF 2021 Survey results. We looked at demographics of survey respondents and their feedback to the board on 2020 actions like establishing new committees and fundraising.

I’ll start with a recap of survey respondents vs. the general editing population of OSM. Jennings Anderson also posted yesterday with a view of worldwide mapping behavior and a simple methodology for determining who’s a local mapper for each survey region. This first map shows the number of survey respondents per 1k local OSM mappers, ranging from fewer than 10 in Indonesia and the Middle East to 35+ in Belarus:

xxxxx

The geographic survey responses are aggregated to preserve anonymity, in some cases grouping dozens of countries under a single region. The maps on this page show simple survey results using the Board’s country-to-region mapping to make the responses easier to interpret. To re-create the map above, and all other maps in this post, source tabular data, region GeoJSON, and a QGIS file are available in a Github gist.

All maps here should be considered “No Rights Reserved,” CC0, or public domain.

2021 Board Priorities

Survey respondents were asked to prioritize the OSMF’s activities in the next year by ranking seven possible tasks in order:

  1. Stability of the core infrastructure (hardware, software, human capital)
  2. Outreach to Local Chapters and Communities
  3. Takeover protection
  4. Fund-raising
  5. Recruitment for Working Groups
  6. Attribution guidelines
  7. Brexit

The rank order makes this difficult to summarize on a map. Fortunately, the OSMF already elects its board members using a ranked-choice voting system called Scottish Single-Transferable Vote, so I’ve applied that method to the survey responses. I’ve scored priorities for each separate region with one, two, and three possible winning choices to determine overall community sentiment about each of the seven possible choices.

First priority for OSMF by region

There is clear, strong alignment on core infrastructure stability as the top global priority. Almost all regions chose this as their first priority, and the ones that did not chose it as their second. Stability is a clear winner.

Second priority for OSMF by region

Takeover Protection and Outreach emerge as the next two priorities, approximately neck-and-neck. Protection from hostile takeover of the OSMF is important to European respondents, while outreach to local chapters and communities has a strong showing elsewhere.

Third priority for OSMF by region

Fund-raising rounds out the top half of the priority list for the board. Working group recruitment and attribution guidelines appear in just one region apiece, and Brexit did not appear important to respondents at all. I interpret this to mean that Brexit-related changes for the UK-based Foundation are an administrative or procedural task that the Board is expected to handle through delegation.

Technology Policy

Survey respondents were asked for their opinion on two hot-button technical issues, AI/ML techniques for expanding the map (sometimes known as “robot mapping”) and a long asked-for vector tiles service to complement the existing OSM.org raster tiles.

Regarding AI/ML, the survey asked for a single response to this question:

Some OSM community members favor use of artificial intelligence and machine learning tools to assist mapping.  Others oppose use of these tools.  The Board of Directors of the OpenStreetMap Foundation has taken no position on the matter since such a decision would likely violate the core principle that the Board does not tell anyone how to map or what to map.  Should the Board…

  • “…adopt a policy banning artificial intelligence/machine learning tools?”
  • “…continue to take no position (i.e., leave the issue to local communities), since the Foundation tells nobody what or how to map?”
  • “…adopt a policy formally approving artificial intelligence/machine learning tools (blanket approval)?”
  • “…adopt a policy formally approving artificial intelligence/machine learning tools but only if local communities agree?”
  • No opinion

Community responses settled on two leading approaches: continuing to take no position, or formal approval of artificial intelligence/machine learning tools conditionally if local communities agree.

OSMF AI/ML Policy

Regarding vector tiles, the survey asked for a single response to this question:

Some OSM community members think the Board should fund change of the map displayed on openstreetmap.org from raster tiles to vector tiles.  Bearing in mind the potential cost of such an undertaking, and the possible impact on the OSM ecosystem, in your opinion the Board should…

  • “…pay developers to create vector tiles for openstreetmap.org, but in a manner calculated not to compete with commercial developers.”
  • “…do nothing in this regard.”
  • “…encourage volunteers to create vector tiles for openstreetmap.org, but nothing more.”
  • “…pay developers to create vector tiles calculated to demonstrate the full breadth of OSM data.”
  • No opinion

Community responses settled on three leading approaches: encouraging volunteers, paying developers to demonstrate full breadth, or not offering an opinion at all.
