 Command-line applications have a hard time with OAuth, because it requires a browser. The auth flow has so many steps, it was much easier to just give up and use Basic Auth with a password. Taking a hint from a Google's library, I made cli-oauth2: a Python library that makes authenticating a one-line task. https://github.com/Zverik/cli-oauth2 Fun fact: the idea came when I was rewriting Level0 for command-line. Didn't get it to work (yet haha), but there's one less problem to solve. 41 comments
 @zverik Does the script also change IDs? What does "fix ids" mean? For readers' info, Organic Maps Editor doesn't store IDs and doesn't rely on them.  @organicmaps @organicmaps To upload objects to the sandbox, you need to give them negative ids and keep the references. This is not related to OM, just a low-level API stuff. (should mention that there are TONS of nuances that don't fit into tweets.) Two main issues with the proposal that don't make it a perfect one: - It's too wordy, nobody would read it, despite the core idea is very simple (stop nodes). - It challenges the current tram stop mapping (and nothing else). The new PT schema should've been perfect in 2018 to be approved, and now it should be double-perfect, otherwise it won't pass any discussion. Everybody in OSM has their own opinion on PT mapping. Keeping an up-to-date rendering database means relying on worldwide replication streams from osm.org or per-country streams from @geofabrik . But what if I want my own extract area? In 2014 I dug into osm2pgsql's "slim" tables, and wrote a script to trim the data outside a given polygon: https://github.com/Zverik/regional I use it for my "veloroad" tile server, but not sure if it works: the database grows pretty fast. Maybe it's just because people are mapping more than ten years ago. @zverik @everydoor @josmeditor wow, that looks like it can improve the editing workflow a lot @TheStroyer @everydoor @josmeditor Indeed! Just last Sunday I was walking with my friends in a forest, and surveyed a few streams and boardwalks this way. They would be lost if not for the drawing feature. Editing ways properly (e.g. in @vespucci_editor ) needs too much involvement, compared to just a single finger movement in ED. @zverik @everydoor @josmeditor @vespucci_editor can you choose a color? That would be useful @TheStroyer @everydoor @josmeditor @vespucci_editor kinda see my sunday notes for an example https://geoscribble.osmz.ru/#17/59.24465/25.68334  @zverik @TheStroyer @everydoor @josmeditor why draw? just record a GPX track ... PS: in a forest you probably want to use a DTM anyway for tracing. PPS: not to mention that you are massively overstating the effort to simply directly add things. Since we're mentioning @josmeditor , here's one thing I made a long time ago: Yeah, that's a proper landing page (in Russian), with a few buttons, shortcuts to most important pages like a forum thread or a tag list, and a tutorial video. I even browsed the changelog and added interesting changes to the feed, but stopped in 2020. I still use the page to download updates though. I'm a bit out of breath, but def not out of projects :) Gonna keep doing this until I get an answer from NLNet. In 2010 Microsoft granted to OSM permission to trace Bing imagery. It was the only detailed imagery layer we had in Russia, so that enabled making a validator that found illegal imagery usage (google / yandex): Basically it watched where people uploaded buildings and checked for available Bing imagery. In 2014 we got Mapbox layer, and I turned this off. There are different kinds of imports. Safest are those done by hand, but also the dirtiest, in my opinion: it's easy to miss or to get lazy and just press upload. For towns and villages, the best source we had was GNS, an american database of toponyms. I converted it to OSM format and wrote a short manual on copying it onto the map: Interesting that while box=yes parameter doesn't work on osm.org nowadays, parameters minlat, maxlat etc still do.  @zverik Still loads of redundant GNS tags on place nodes in Ireland (probably imported by Dermot - mackerski). Until the townlands project got going they were still the major source of places in rural Ireland. Still a lot of dedup & other cleanup needed. I also did a bit with them for Pakistan, but never could trust the data in a country where the population had increased so much : http://sk53-osm.blogspot.com/2011/03/garmin-overlays-of-gnis-names.html (probably should correct GNIS->GNS Having a GeoJSON to preview an import is good, but how to suggest amendments? That's why I made CF Audit: an interactive website to go through changes one by one, cross-reference them, and fix anything wrong. Those fixes are kept for consequent imports with OSM Conflator, so less work next time. I know RocketData iterated on it for their operations, and there's a new IFS fork by @sfkeller team: https://cfauditgui.geoh.infs.ch/ So I got the conflator, and I got the audit tool, and the entire pipeline as shown on the picture. Did I use it? Oh did I even. 5k Walmart supermarkets, tens of thousands Shell fuel stations, ~10k addresses in Moscow, various restaurant and shop chains... It all worked perfectly. Of course it was just a few imports. I envisioned an automated system for high volume of data, still controllable by OSMers, but nobody asked for that, and I didn't have time. Still, mentioned it at SotM EU 2023. You know OpenWhateverMap. Grant made the original version, then we lost the domain, and then I updated it with modern tiles and some interactivity: clicking on a tile reveals its name and URL. For the @sotm in Firenze I went all-out with the remote participation part. One thing I did was a Telegram bot, where people from anywhere could introduce themselves. The idea was to put a face to hundreds of names on online channels. Because once you have a face and a voice attaches to words, it's impossible not to feel a proper conversation going when you type. Not many people contributed, but still, was fun. The bot was disabled after the conference ended of course. For a very long time the leading repository on my github was "leaflet-grayscale" with a hundred stars. I love @leaflet and made too many plugins for it. This one was quite simple — but I guess useful enough. It just makes the map grayscale. There are too few layers fit for a visualization background. Sometimes removing colors (and labels if possible) is good enough.  Back to OSM, here's one you'd ban if you could. Sisyphus make a person's mapping work as pointless as rolling a stone up a mountain. It plain reverts every changeset a person uploads to OpenStreetMap. We used it in Maps.Me for reverting edits of our QA team. Not ideal, which Frederik noted, but it works, the map is clean, no hassle with moving data to the sandbox. Uses simple_revert as a library, of course. That library is underrated. People usually need three things from maps: tiles, geocoding, and routing. Three things too mundane to work on. For Maps.Me Changes Monitoring, I filtered edits by countries. For that I wrote a simple reverse geocoder: QueryAt. It returns a country, a region, and a populated place for a given location. 3 GB database for the entire world, no configuration or query parameters. Won't recommend using it now though: 8 years later, you could do better.  |

This one came up yesterday, while preparing for @organicmaps GSoC student work.
When developing an editor, you need to work with OSM Sandbox, a dev copy of API with no data. Sometimes it's frustrating because complex data is where an editor breaks. Usually I downloaded an OSM extract in JOSM, fixed ids, and uploaded it to the Sandbox, but on the 100th time I gave up.

This script helps you transfer a bbox worth of data in two commands, one of which is pip install.
