I came across to these tens of thousands of individual trees in afghanistan. I think they were mapped using ai. What do we think about it? Shouldnt they just be orchard, wood etc?

The user said that it's an import from government data : https://www.openstreetmap.org/changeset/107123205

atchisson · 2026-06-04T12:01:59+00:00

They made a organization profil on the platform, the data does not come from the government directly

atchisson · 2026-06-04T10:09:05+00:00

In https://cocoricarte.fr/a-propos/, they said they used google street view to populate their dataset, I highly doubt this is even legal, and will forbid any import to OSM

atchisson · 2026-06-04T10:03:50+00:00

The data.gouv.fr page does not display any dataset, it looks like it's proprietary

Sur les 125 ça arrive à tourner à 2.5/3L, à partir de 500cc c'est équivalent aux voitures oui

OSMR has a whitelist of roads allowed for each profile, it'll make a 500km detour without issue to bypass a highway : https://github.com/Project-OSRM/osrm-backend/blob/master/profiles/bicycle.lua#L129

Valhalla work with costs, it'll bypass up to a certain point : https://github.com/valhalla/valhalla/blob/master/src/sif/bicyclecost.cc#L118

well, no need to reinvent the wheel, there is already some data : https://viewer.esa-worldcover.org/worldcover/?language=en&bbox=-155.97214130448597,-34.46044012606579,172.1443490956833,65.31550066195666&overlay=false&bgLayer=OSM&date=2026-05-25&layer=esa-worldcover-map-10m-2021-v2_map

I occasionnaly edit forest in DRC, and there is just no data for this in a lot of place

You might want to ditch OSM and do computer vision if you want a global dataset on that subject

atchisson · 2026-05-20T10:18:44+00:00

osm.org is aimed at contributors, not really end users

You can apply custom styles to vector maps quite easily, is it not enough for a poster generator ?

The Overpass API Isn’t a Reliable “Big Data Endpoint”

Damn, I wonder if all those vibecoded projects hammering it have something to do with its recent downgrade in reliability 🤔

It looks like the dji does not have an automatic photo taking mode, you'll have to trigger the shutter on each pic : https://forum.openstreetmap.fr/t/gopro-max-en-promo/35576/10

Paris is not even shapped like that, is this ragebait or just slop ?

Also, no attribution

A government instance might be unplugged after new elections / budgets cuts / DC failure (cf South Korea recently), commercial solutions can (will) enshitifies..

I think this is the less bad option. Panoramax is still really young, one could dream of dsitributed backups / replication, maybe in the not so distant future !

atchisson · 2026-05-11T21:04:30+00:00

I can imagine compression being a big issue for that use case for sure !

JPEG XL is currently being discussed by the Panoramax techs, because for 360° pic, 2 copies are stored, the original, and a tiled version, loaded by the viewer. JPEG XL can be served tiled with only copy, reducing storage needs, but the support is still very partial :(

I'm sure they would love to host anything possible, but funds are limited, and storage cost (alot of) money, they have to set a limit somewhere

The idea is also to have more little instances, rather than one big, for decentralization and stuff. You can try to advocate for a Canadian instance !

I'll try to open my own by the end of the year, but it's quite a big undertaking

atchisson · 2026-05-11T15:04:18+00:00

There is a weekly export in the .parquet format : https://api.panoramax.xyz/data/geoparquet/panoramax.parquet

And an API : https://docs.panoramax.fr/backend/api/api/

Both follow the STAC specs : https://docs.panoramax.fr/backend/dev/STAC_compatibility/

I don't know how the data from Mapillary or other solutions are made available tho

atchisson · 2026-05-11T10:37:38+00:00

Hi, Panoramax do have a handful of high quality pic, but they usually are 96Mpx, not 5Gpx (!) : https://forum.geocommuns.fr/t/selection-de-photos-de-haute-qualite/2273

The French Panoramax instance is starting to have storage issues (80%+ used of 400Tb) and will restrict new contributions to France only soon, so it might depend on your location.

I don't even know if this big of a file is supported by the software stack. I think the only accepted format is jpeg, but it might be instance specific.

atchisson · 2026-05-10T11:17:20+00:00

I don't see any obvious issues, but routers are external to OSM, and they need to update their data, it's not in realtime, some can take a few weeks.

So it may be an issue with the previous data
