I completed my first 100+ physical addressing on Magnolia Ave., Birch Run Ave., Redwood Rd., Hickory Rd., Elder Pl., Hemlock Dr., and Beech Pl. The project took about 3+ hours to complete. I’m new but will soon get into other tasks. ChangesetID: osm.org/changeset/145716852

I got my husband to join me and help me with mapping today. We went from approx. State Line Road in KC on 43rd St (we think of it as 43rd though there is a stretch that’s Westport Rd) and down to the west end of it just beyond Mission.
We went to Sway Coffee Roasters and had a nice cup of coffee/tea, and got to say hello to some sweet dogs that another customer brought with them. The dogs visited everyone within leash distance and everyone seemed happy to see them. Little random encounters are what make me love the city so much.
My plan next is to visit the stretch of 43rd east of Gillham Park, and to touch some of the “nodes” I skipped over when going along the length of it, like St Luke’s and various parks etc.
QPFF+F9R, QPFF+CFR, Grand Trunk Rd, Wah, Cantt, Rawalpindi, Punjab 4700, Pakistan
Satellite Town is the Controlled Area near by GT road and Basti Lalarukh wah cantt. A ghost Town in triangle shape with the flavor of dead end.
It was fun editing Leboya bay, it was missing some information and buildings. We went for three days camping and I had fun surveying the area and discovering what the camping site had to offer.
Based on a coincidence, I used Overpass in my area to try to identify objects marked for removal that are older than period X. Unfortunately, I didn’t manage it so easily and at the same time had the idea whether it wouldn’t be better to check this on site via street complete. In the course of the GitHub issue, however, it turned out that it doesn’t really fit the core of Street Complete.
So back to Overpass and the good old query in advance to be able to check it later on site. With the help of other OSM users on Telegram, the following query was created, which can be easily customized:
https://overpass-turbo.eu/s/1Fml
To be on the safe side, the overpass query is shown here as code:
//Check for Stages of decay
//based on the idea of:
//https://github.com/streetcomplete/StreetComplete/issues/5402
[out:json][bbox:{{bbox}}][timeout:800];
//gather informations about non-excisiting objects
//and store the data as "gone"
(
nw[~"^demolished:.*$"~"."];
nw[~"^razed:.*$"~"."];
nw[~"^removed:.*$"~"."];
nw[~"^destroyed:.*$"~"."];
)->.gone;
//substract any gone-object, that was last modified
//within the last X years
(.gone; - nwr.gone(newer:"{{date:1year}}"););
out geom;
Start time: 6:42pm End time: 7:49pm
A major rewrite here takes into account tags such as natural, reef, wetland, surface and tidal before deciding how to show wetland areas. See the picture above, which is here, and here in OSM.
The beach between high and low tide can be clearly seen here (in OSM, here). There are blue dots in the sand rather than black. A deliberate decision was taken to show more detail for areas above low tide. See e.g. here between Wales and the Wirral (see here in OSM).
Over the last few days I have been chipping away at validating tasks for the #osmIRL_buildings project.
I have now just finished validating all of Howth. There is still a good bit left in the rest of the county, some of it will definitely be quick due to some areas being rather rural.
As I’ve noted elsewhere, I’m working on moving the JOSM plugin repository from svn to git.
I’ve managed to get something for most authors, but I am still missing attribution information for 47 authors with 95 commits between them.
If you have previously contributed to the JOSM plugin svn repository or the OSM svn repository (which used to include the JOSM plugin svn repository), please reach out to me via OSM messages or email (tsmock@meta.com, taylor.smock@kaart.com, or smocktaylor@gmail.com) if the attribution for your contributions is missing or wrong.
What I need from you:
noreply email addresses if privacy is a concern for you.Notes on the conversion:
patch by <foo> commits have been modified such that the originator (“<foo>”) is shown as the author, while the committer remains unchanged.git lfs could be used for this prior to the final conversiondist directory for plugin releases has been excluded from the test repository due to size constraintsWIP Repositories (please do not fork these; I may rebuild them at any time as I get new attribution information):
Earlier this month during Wikidata Data Modeling Days Hannah Bast from University of Freiburg presented QLever, a SPARQL query engine with some really cool features (slides, recording). After a month of using it, in this post I’ll discuss how it’s relevant for the OSM community and my experience so far.
SPARQL is a query language for RDF data, which can come from RDF-native knowledge graphs (there are thousands of them, public and private, the best known in the OSM community is Wikidata) or other sources (for example OSM) converted in RDF with some tool or middleware
SPARQL includes an optional extension for geospatial data, geoSPARQL. Query services implementing it allow to run all kinds of spatial queries with a naming similar to other query languages based on OGC standards (like SQL on PostGIS).
One notable feature of RDF and SPARQL is that they are made from the ground-up for interoperability between different data sources (“linked data”). SPARQL natively supports querying multiple RDF data sources in one single query through “federated queries”. This works by specifying inside the query to the first service the URL of the second service and its query, then specifying how the result should be merged or joined to the data from first service. If the second service is not blacklisted, the first service will handle autonomously the communication, merge the data and return directly the final output.
QLever and osm2rdf are two projects by the University of Freiburg; they were introduced respectively in 2017 and in 2021 but only recently started getting attention in the OSM world.
osm2rdf is a tool for converting OSM data into RDF. It transforms geometries from OSM’s node-way-relation format to Well Known Text (WKT) and can indirectly materialize containment and intersection relations between elements to improve spatial querying speed. It’s FOSS and extracts of the data it generates are available online.
I have started an independent collection of OSM SLA statistics. Approximately once a month, I will publish my results with the aim of enhancing transparency regarding the reliability of OSM services. I use uptime-kuma to run monitoring. I also verify connectivity with non-OSM services (to prevent false positives). The current configuration includes checking the availability of openstreetmap-website and openstreetmap-cgimap (API). Tile layer availability is not currently included in the checks. The health-check resolution is set to 30 seconds, and the checks are executed from a single server in the Hetzner datacenter in Germany. For the endpoint to be marked unavailable, two consecutive checks must fail. This should be well-representative of an average user experience.
Total API downtime: 2 hours 34 minutes 13 seconds
API SLA: 99.643%
Total website downtime: 43 minutes 15 seconds
Website SLA: 99.900%
Note that some functionalities of the website require API to also be available.
The 30th of November saw the 4-year anniversary of the #osmIRL_buildings project, an ambitious project of the Irish OSM community to map all the buildings on the island. Co. Kilkenny had been the first project to be finished in the task manager in April of 2020, and I thought that it was high time to look at it again.
Since I live in that county, I had noticed missing buildings once in a while being on the road or mapping other things remotely. Relatively new (summer 2022) aerial imagery had been made available by Esri World which wasn’t as clear as Bing, but more recent.
So I decided to make a private task in the task manager and update the whole county by myself. I like to have side quests to make it more interesting, so I decided to also look for unrecorded archaeological sites. The summer of 2022 had been very dry, so crop marks would be more visible on the Esri World imagery. I wanted a private task, so nobody would map any of the tiles, and I might miss something. I usually map the bulk of the other tasks anyway, but I did not want to take any chances. This was going to be the most thorough search for crop marks and other clues to archaeological sites Kilkenny had ever seen. Or so I believe.
All in all, it took me 11 days or 75.5 hours (average time per task multiplied by tasks), but I had excluded Kilkenny city, because I usually have an eye on that all the time.
I started mapping by updating shop details in my area and have now moved on to helping OSMirl in completing the various tasks to get all of Ireland on the map.
I have also started adding buildings to my home city of Port Elizabeth, South Africa. The majority of the suburb (that I’ve worked on) does not have any of the houses mapped.
started to map minor roads and paths in Hahei in the Coromandel, because there sure are a lot of them. already done about 3 minor roads. not that anyone is ever going to use them other than the few locals that already do, but it’s probably got some use
As always at the end of the year comes the time for summaries and plans for the coming year. Since a great deal of my activities is related to OSM I would like to share my plans with you for the the coming year of 2024. Despite not managing to achieve everything I planned (this year, the previous year), there was still a lot going on. So let’s start with a summary of the events of the year 2023:
Unfortunately, the list of plans that didn’t work out is much longer than I would like. This is what happens when there is not enough time or resources, and sometimes things just don’t go as intended.
hi!!!!!! i am new to osm and mapping in general. made my first edit/change yesterday! hopefully many more to come.
Yesterday I mapped a tiny area with lots of shops, bars, etc. This stretch of 43rd is so dense and diverse, it is really interesting. There are high-end establishments, but also a church and a food bank, convenience stores, a Mediterranean market. Next survey of the west portion of 43rd I think will go quicker as it becomes more suburban.
Some highlights:
I realized I need to add bulletin boards to my ‘look-for’ list - I found two of them in this little stretch, at a cafe and a record store.
Did not know there was a Mediterranean market so close to my neighborhood!
Found an interesting looking cafe I had never heard of (though it was closed at the time - will check out later)
Random excrement bag dispenser in a residential area on the way back - it’s silly but I love finding these, like a rare item in a video game :)
I am making my way along 43rd St in Kansas City, mapping most of the amenities and businesses I see along the way. About two weeks ago, I went from where 43rd breaks off at Gilham then west to Donutology, and today I worked through the stretch between Donutology and west to the nearby QuickTrip across from the Catholic church. I did not get very far because I walked into many of the businesses and chatted with folks, so as not to be suspiciously loitering outside :D
It was really fun to explore places I wouldn’t normally think to go to. I walked into Gigi’s Health Cafe (the proprietor saw me outside and came out to say hi, so I explained what I was doing and showed her the Every Door app where I was entering her business’s info), and also Paris Banh Mi, which looks like not much on the outside, but is really quite lovely inside.
I have lots of photos that I haven’t decided where to upload yet, but that will be its own project later probably. Along with various points of interest, I started taking photos of all the light poles and street cabinets that I notice which are covered with stickers and/or graffiti. Temporary signs fascinate me. Not sure if there’s a place for photos like those on OSM but I’m keeping them for something at any rate.
On my impression of OSM as a newbie: It looks like there are not a lot of active Kansas City mappers, and that anymore, most of the updates are done by businesses or by people who create / use automated tools, and the most active people are the ones getting deeply into the technical side. A lot of the diary entries I see are about conferences and full of dense technical and/or organizational jargon. Lots of businesses and nonprofits seem to be involved.
