Here I go again…. part 2.

I was pleased to see someone pick up on my first diary item. OSM weekly is hardly the New York Times, yet I know that the editors like posts which are constructively critical, and they did spot that I was hoping for something to happen which would let us all “do better”.

I decided to look in more detail at how the lack of detail was leaving validators with a lot of mapping to do. Evidence of this is seen here, where the mapper marking the tile as “completely mapped” is nowhere near being the main contributor of objects and the validator – DeBigC – has add or adjust 62% of the objects in the tile. This shows the last mapper to touch any object. Note: I do accept that this is one tile, but it’s not unusual to find this all over the Fingal task.

As a friend and I were adding the 57th tag to a climbing gym in Belgium, I wondered what the element with the highest tag count is. I couldn’t find such stats (which may be a good thing), so I downloaded belgium-latest.osm.pbf from Geofabrik and wrote a simple Python script that uses Pyosmium to do some counting for me.

Without further ado: the Belgian record for highest tag count is… the relation for Belgium itself actually, which currently has 491 tags. The non-relation with the highest tag count is, boringly, the node for Belgium, with 288 tags. Next up are Brussels (156 tags), the Council of the European Union (79 tags), one particular section of the River Meuse that somehow got its name mapped in 57 different languages (65 tags) and the Irish embassy (also 65 tags). Next up is the first element that has a lot of tags not because it’s just flooded with languages! This maritime beacon north of Antwerp in the River Scheldt has a respectable 63 tags to describe all its lights. Our climbing gym is not far off from this one, and has a lot more diverse information in its tags I’d say.

I noticed that the relation for Belgium also has a high version number, it’s at its 1043th revision. That prompted me to take a look at version numbers too. But 1043 isn’t even close to our record, which goes to the superroute relation for the E40 (version 3141). Granted, that’s international. The version record for a purely Belgian object is the hiking route GR 126 (version 1103) from Brussels to Membre-sur-Semois. Just like with tag counts, I find it more interesting to look at non-relations here, though. There the honour for highest version goes to one of the outer rings of a farmland multipolygon south of Mons, which is at version 277. Funnily enough, in contrast with its senior version number, it almost has no tags to speak of, only a source!

I created this for my own use, but am sharing it here because it might be useful to other people too. This is the style and there’s a brief readme.

It uses different colours to highlight different map layers. It’s not supposed to look nice; just to show you what is there.

I believe that everything described in the schema is included. If a feature does not appear it might be because:

• it’s not in the Shortbread schema.
• it’s in the schema, but is for some reason missing from the OSMF vector tiles.
• it’s in the tiles, but there’s a bug in this style.

There are lots of features in the first category, and there seem to be a couple in the second. If anyone finds anything in the third category please let me know!

In dipalpur okara Punjab Pakistan

Severe floods and landslides devastated Sukabumi Regency, West Java, after two days of intense rainfall, with over 100 mm of rain falling in a short period, according to the Meteorology, Climatology, and Geophysics Agency (BMKG). On Wednesday, December 4, the overflow of the Cikaso and Cibening Rivers inundated numerous areas, displacing residents and severing access roads. The hardest-hit areas included Palabuhanratu, Sagaranten, and Pabuaran. Floodwaters reached heights of 80–90 cm, submerging homes and halting transportation.

In Sagaranten, neighborhoods like Kampung Rangcabungur faced dramatic rescue operations as narrow alleys flooded waist-deep. Rescue teams, battling strong currents, evacuated several infants and their mothers. “We successfully rescued two to three babies. It was a tense process, but thankfully, everyone was saved,” said the Head of the Sukabumi Police’s Samapta Unit.

Today, panning in Kampala, Uganda, I noticed so many place=village and place=neighbourhood , often the same name is duplicated.

MapSwipe on the Web Experience

Recently, I had the privilege of leading a MapSwipe training session for a corporate group, and it was an incredibly rewarding experience. While I’ve conducted online trainings before, this one felt particularly special. Despite my initial nerves, I was able to deliver a smooth and engaging training session.

Initially, I felt a bit nervous about taking on the role, especially since I was filling in for a colleague. “Corporate” to me also sounded really scary and extremely formal. However, with a bit of preparation and the support of a wonderful colleague, Nicole, I gained the confidence to deliver a successful training session. I focused on guiding participants through the web version of MapSwipe, a tool close to my heart.

Backround

About 6 years ago now, the Ireland OSM community had a bunch of online and face-to-face discussions. There was a desire to have a common campaign, rather than everyone just paddling their own canoe, mapping old boundaries, addding 110KV monster pylons, plotting the holy stones of Clonrickert, or whatever you are having yourself.

Why Buildings?

And so #osmIRL_buildings was born. It took lots of months to pull together. There was a discussion document put out, and lots of decisions and guidance via videos, long conversations on Telegram, and frequent issues discussed on the mailing lists. The task was designed with a few things in mind. Firstly, the community recognized that compared to other territories, we had relatively small levels of completion of buildings. Secondly, a prominent academic had stated that the Irish Government knew more about the number and condition of cattle than it did about buildings. Thirdly, a lot of citizen science projects were trying to collate and capture where derelict and disused buildings were located in cities, with the hope that they might be repurposed for housing. Fourthly, there was a National Planning Framework launched in 2018 that concluded that the spaces for the next 1 million people to live in could not be sprawl outside of Ireland’s cities and towns. There were other reasons too, but those are the ones I recall, so apologies to all those other reasons and their proponents. Nevertheless, all of the ones I mention here could have been addressed by the creation of a fully open spatial dataset of the buildings on the island, and not what passes for open data by data.gov.ie.

Reservations

Of course there were detractors; some mappers worried about the threat of being inundated by the glibness of millions of “building”=”yes” objects. One man in Kilkenny was worried that the climate would have changed by the time the task would finish. He might yet be right.

Had to write something about this. Well, the USA Geofabrik (Continental + HI and AK) extract is now well over 10GiB. And my poor Garmins still only can handle 4GiB gmapsupp.img files. Yeah, I have to lose over 6GiB of stuff now to get it to fit. I’m not sure how long this is tenable, but yes it’s a continuing struggle to get it to still work…
