erreur région sur le logiciel Heredis 2021 11 months ago

Ce genre d’erreur semble étonnant mais ça peut arriver. Quelles sont les communes mal localisées ? Cela vaudrais aussi la peine d’ouvrir une note (bouton sur la droite, sur la carte) pour chaque commune, ce sera plus visible qu’un billet de blog.

Ringforts in Ireland, astonishing historical heritage 12 months ago

Don’t confuse hill_fort and ringfort. Ireland mostly has the later.

We have a few more subtags, but they aren’t very standardized yet (check taginfo) and some are quite technical.

You might also want to check our resident archaeological expert’s youtube videos which have interesting Ireland-specific info about tagging and sources.

All from Bing about 2 years ago

Why restrict yourself ? There are other sources at our disposal, and Bing isn’t always the best.

Quick update on Maxar imagery over 2 years ago

The technical side of creating a proxy shouldn’t be too hard: get a server with a big disk and a lot of bandwidth, restrict access to OSM accounts via Oauth, and make sure different actors (not just OSM Foundation) can setup and federate caching for the same sources, and make it easy to update the software and sources list.

That’d (hopefully) solve Maxar’s issue, but would also be a clean ready-made solution for things like Strava or one-off HOT imagery.

The trickyer part of the problem is financing the bandwidth and worldwide servers. Bing is big enough that OSM takes just a small fraction of their resources. Mapbox has OSM in its DNA. For smaller and less engaged players, we’ll need to foot the bill, wether OSMF directly, using a big sponsor, or using lots of small sponsors and great federation..

Bye bye, mapping over 2 years ago

I see a lively discussion in https://www.openstreetmap.org/changeset/77387716, that’s good. Hopefully you’ll reach a consensus (I’m not good enough at Italian to see if that’s the case).

If that discussion doesn’t work, try reaching the https://wiki.openstreetmap.org/wiki/Data_working_group

disparition de "la vélodyssée" EV1 ! disappearance of the "velodyssey" EV1! almost 3 years ago

https://pewu.github.io/osm-history/#/relation/4774799 est pas mal aussi. En suivant quelques liens on trouve http://ra.osmsurround.org/analyzeRelation?relationId=4840311 et http://ra.osmsurround.org/analyzeRelation?relationId=4840316 qui sont actuellement cassés.

disparition de "la vélodyssée" EV1 ! disappearance of the "velodyssey" EV1! almost 3 years ago

En regardant l’historique dans JOSM (Ctrl+Shift+O pour télécharger juste cette relation, Ctrl+H pour en voir l’historique) ça n’est pas super compliqué de voir qui a fait la modif. Il existait un équivalent web mais je ne le retrouve plus.

Je n’ai pas regardé de près, mais on trouve les récents changesets https://www.openstreetmap.org/changeset/70689443 et https://www.openstreetmap.org/changeset/71923457 qui ont ajouté puis retiré deux chemins.

Mais apparement la relation qui t’interesse est une super-route (contiens d’autres routes plutôt que des chemins), donc il c’est plutôt dans l’une des sous-routes qu’il faut aller regarder. Ouvre une des routes et utilise les onglets “relations parentes”/”relations filles” pour accéder aux autres routes et voir lesquelles ont des trous.

#CrimeaІsUkraine #DWG #CrimeaMap #КримЦеУкраїна #ИхТамНет over 3 years ago

How many more times are we going to see this copy-pasted diary entry ? Please stop spaming the same message again and again, all the arguments have been given already, more posts will only suceed in irritating readers.

#CrimeaІsUkraine #DWG #CrimeaMap #КримЦеУкраїна #ИхТамНет over 3 years ago

@redsteakraw there’s really no need to rub in more violence. The law of the strongest stems from a different era, and always comes biting you in the end.

@velmyshanovnyi sorry but you’re complaining at the wrong place. There’s nothing illegal in OSM depicting the de-facto borders rather than the borders as recognised by the UN or UK (or some other fancyfull fictional border for that matter). Only diplomacy and millitary can change the situation.

#CrimeaІsUkraine #DWG #CrimeaMap #КримЦеУкраїна #ИхТамНет over 3 years ago

As sympathetic as I am to the idea that the Crimea annexation was illegitimate, should have been prevented, and should be reverted, please give the DWG and OSM in general a rest, as it’s only following the https://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf directive dated from 2013 that represents the consensus from the OSM community. If anything, the most recent DWG decision just restores normality in OSM’s handling of disputed territories, by cancelling the temporary exception for Crimea that was in place (for many good reasons basically boiling down to “this is too new and controvertial, let’s do nothing until the dust settles a bit”).

If you want things to change (appart from Ukraine actually regaining control of Crimea), it’s the disputed territories directive that you need to challenge, not the DWG’s implementation of it. Propose changes to it and see if those can gain wide support. Note that this document is about all territory disputes in the world, nothing specific to Crimea or anywhere else. The current policy tries very hard to be impartial, objective, and apolitical; this leads very naturally to the “on the ground control” rule, which you apparently want to ignore in Crimea’s case. It’s always easyer to agree to a general policy when you’re not affected by it.

While we’re at it, I’m surprised to read so much backlash at OSM, but nothing at (for example) Google maps, which has displayed Crimea as part of Russia much earlyer than OSM. Yes, I know this depends on the viewer’s IP address, but these IP-guided non-decisions (GM does that in other parts of the world) have always seemed worse to me than OSM’s pragmatic objectivity stance.

#An accomplished set target to beat UMT queen, Valerie143 with a total edit above hers#uniquemappersteam# over 3 years ago

Don’t get too taken up by leaderboards. They’re fun, but if you’re “mapping for the leaderbord” your mapping quality is likely to lower, because you’re optimizing for that leaderboard’s metrics (typically number of objects edited) instead of map quality and maintainability (which often involves limiting the number of objects).

I’m not saying that you actually fell into that trap (I didn’t check), but I see a high risk of it when I read this diary.

Also, please put individual comments in your chanesets to briefly describe what you did. Changeset comments are human reviewers first, stats collection second (if at all).

Welcome to OpenStreetMap! about 4 years ago

These are obviously exagerated quotes, so what are the real ones ? And how common is the problem ?

Building an inclusive map - OSM and gender discussion over 4 years ago

Don’t conflate the sometimes-problematic tone of OSM discussion with the issue of gender and minorities inclusion. They are both real problems but they are orthogonal (men can also be put off by a toxic discussion and women are also able to make a discussion toxic). Try to solve both problems as one and you risk solving only one of the problems.

¯\_(ツ)_/¯ over 4 years ago

Sigh… He should know that Mew2 can only be caught at exclusive raids, not in the wild :p

PoGo Initiative: entry 2 xD over 4 years ago

BTW, regarding the “disconnect between in-game and real world” you mentioned last time, I feel that disconnect is bigger when the buildings are mapped, because your avatar is way too big compared to the houses. The avatar scale never bothered me when I could only see the streets because GM only has a handful of buildings here, whereas OSM has all of them. Don’t let that stop you from tracing buildings :)

PoGo Initiative: entry 2 xD over 4 years ago

Most imagery needs to be aligned. Bing is pretty good to begin with but it’s better to check, especially in mountainous area. See https://wiki.openstreetmap.org/wiki/Using_Imagery and https://help.openstreetmap.org/search/?q=align&Submit=search&t=question .

One of the best reference data to align imagery on is GPS tracks on road, if you have enough of them (when it’s no longer easy to distinguish individual tracks). You can download OSM GPS track using your editor, or you can use the strava imagery layers, which present aggregated track data.

Pokemon Go made me start editing OSM over 4 years ago

It seems that the current version of OSM data used by Niantic is a few months old. I guess they’ll only update “every now and then when they feel a need” rather than regularly, as that seemed to be their update pattern with OSM data used for nests. Maybe the PoGo community can incite them to update more frequently/regularly.

Regarding the “win some lose some”, it’s always the same when going from one map provider to another. For me (Ireland) the switch to OSM is a great upgrade, and I’d say most regions of the world will either find OSM better or equivalent to GM, except in North America where GM still has better data (I’m talking about the broad picture; zoom in and you’ll see exceptions either way).

That blade of grass is coming back to haunt us. almost 5 years ago

One of the main goal of most renderings is to look lovely, so it’d be reason enough. Plus it’s actually useful to know what kind of sport is played on a particular field.

Concerning the OP, see this help.o.o question for a previous discussion about it. I’m still of the opinion that we shouldn’t map pitch lines, but this is apparently not unanimous.

One thing that commenters agreed on is that barrier=line is the wrong way to go. You should tell the contributor to find a better scheme. Maybe also him the french and german rendering styles, as well as this issue for the default osm.org style, it might satisfy his wish without bloating the db.

OSM x GM's "glitch" about 5 years ago

The Rio de Janeiro favelas should be good candidates for a resident-led slum mapping, like happened in Kibera. I wonder if there are big OSM contributors living in Rio who could mentor this.

Possibly importing USGS forest data about 5 years ago

The most common way to convert pixel values to a shape (the term ‘contour lines’ is usually associated with relief) is to use a “lakewalker” algorithm (surely not the proper COMP-SCI term, I’m just using the name of a JOSM plugin here). You can use other tools, but that one should work relatively well.

Go ahead and try it actually: install the scanaerial JOSM plugin and use it on one of the dataset’s imagery. You’ll get a feel of how well it works. Don’t upload your work unless you have checked that the license is OK. Now think about doing this automatically at a larger scale, and about conflating this new natural=wood with any existing osm data.

My guess is that doing this automatically (as an import) will look much less appealing to you after this experiment. But using the dataset as a source to manually run scanaerial on might still be a time-saver. Sometimes, you’re better off doing it manually than algorithmicaly. Your call.

Concerning the Bing vs Landsat argument, consider the fact that Mapbox updates its landsat source (wherever no highres imagery is available) automatically, and is going to be much better than a 2010 non-averaged snapshot used by that dataset.
