CoMaps – FOSS Offline Maps
- tambre 3mo agoDoes anybody know of a feasible alternative to Google Timeline?
- FireInsight 3mo agoI have set up Owntracks with a self-hosted server, and the android app reports my location to it periodically over MQTT. I would prefer to use https://dawarich.app/ https://dawarich.app/ but last time I tried it it was clearly very beta-quality and not ready for reliable usage.
- forever_frey 3mo agoHi, what were the issues you have encountered in Dawarich? Any feedback appreciated!
- FireInsight 3mo agoI tried it for family location sharing a few months back and, I don't remember exactly, but I remember the UI/UX feeling a bit slow/clunky in general, eventhough setting things up was user-friendly. Definitely potential there, though.
- jpeeler 3mo agoHalf of the solution at least on Android is https://gpslogger.app https://gpslogger.app. Then you need to find a way to render the data to a map, such as with https://dawarich.app https://dawarich.app. Looks like the last time I looked at that project (and wasn't quite sold on it) was 1.5 years ago, so time for a second look.
- HelloUsername 3mo agoProbably posted because of related recent discussion on OrganicMaps https://news.ycombinator.com/item?id=48794446 https://news.ycombinator.com/item?id=48794446
- ivanjermakov 3mo agoWhich was in turn probably posted because I mentioned it on the same day under another submission https://news.ycombinator.com/item?id=48793684 https://news.ycombinator.com/item?id=48793684
- ranger_danger 3mo agoWould love to see a Windows desktop version.
- vfalbor 3mo agoI used to use wikiloc, but most of the things that offer which were the most interesting things were by paying, so I think that it could be some opportunity for using these maps and vibe coding for creating something spectacular!
- random3 3mo agoRelevant thread from yesterday's thread on the original project this was forked from https://news.ycombinator.com/item?id=48794575 https://news.ycombinator.com/item?id=48794575 https://itsfoss.com/news/organic-maps-fork-comaps/ https://itsfoss.com/news/organic-maps-fork-comaps/ > Despite being advertised as a community-driven project, key decisions, including financial management, partnerships (with Kayak, for instance), and the inclusion of proprietary components in the code were made by a small group of shareholders, often without input from the broader contributor community.
- miroljub 3mo agoNitpick: Organic Map is not original project. It's a fork of Maps.me.
- random3 3mo agoAlso forked for similar governance concerns :))
- ponkipo 3mo agoAnother nitpick: at least OM is made by people who made MapsMe. CoMaps is not - developed by a community, whatever it means.
- herrherrmann 3mo agoYou can look up who the contributors are, e.g. in their open-source repo: https://codeberg.org/comaps https://codeberg.org/comaps There are also issues and projects with lots of discussions about what to prioritize, etc. So, bashing that “community” is too fuzzy is perhaps not very warranted. (Although I guess they should add a section “Who makes CoMaps?” to the FAQs or so.)
- miroljub 3mo agoThe fact that OM leadership pulled the same open-closed game twice is telling. Many open source contributors who donated their private time and effort to the project just didn't want to do that any more when OM leadership started the game again. That's the main reason they forked and started a new project.
- nunobrito 3mo agoAnyone here has been using coMaps and care to share their experience, especially in comparison to OrganicMaps? My only complaint to OrganicMaps was the slowness to calculate a direction, which in part is certainly because the path is calculated locally instead of some cloud server but old garmin devices also weren't online and can calculate paths on far less powerful hardware. So I'm guessing there is room for improvement on that part.
- mcv 3mo agoMy biggest issue with OrganicMaps is that the search isn't very good. It really struggles to find my destination sometimes. That's the one thing I'm afraid Google will always be better at.
- dopidopHN2 3mo agoI have the same grippe. I was talking in deep in the weed OSM signal group and apparently its a split between the address data not being present, and OrganicMap / CoMap being bugged. The way to triage is asking nominatim, the geocoder from OSM. If it can resolve : its on the client side, if not, its a data problem. I'm just parroting here. Happy to learn more. This is THE only issue I have with those OSM client ( I don't care about traffic )
- maelito 3mo agoFor good (server) search, one needs many layers (Photon, Pelias with OpenAdresses, Overpass, in-house pmtiles, etc.) using many DBs, each needing server ressources or expensive paid APIs. It's obvioulsy expensive in terms of ops + dev, but also just to host. It can't scale with only 0,0001 % of users donating to the app. Fortunately, NLNet's there to fund work, but it's still nonethless only a tenth of what would be needed. Plus map applications and general search engines don't talk to each other... I don't know why, but it is so. Maybe because all the well-known search engines are closed-source ?
- maelito 3mo agoIt doesn't take so much to enable a good server search on top of OSM + openaddresses. Local search will always be slow and bad. But server search doesn't need that much. It's just that OS initiatives are severely understaffed. OS apps that have a Photon instance are already rare to find. Let's not talk about having an Overpass instance... What is very hard to reproduce is Google's place review data. It's golden to enable good search.
- rickydroll 3mo agoWhile I do use mapping programs for directions, I more often use them for a more accurate estimate of time and traffic density. I haven't looked very hard, but I haven't seen any OpenStreetMap data or equivalent that shows "Real" travel times and traffic density.
- Joel_Mckay 3mo agoIndeed, because gleaning telemetry data from millions of active users isn't a map applications normal intended use-case.
- TechTechTech 3mo agoTried it today. Works fine for navigation. I am missing live traffic info. This is the one thing keeping me in Google Maps the past years.
- jhoho 3mo agoSame. Apparently there's ongoing work to integrate live traffic: https://codeberg.org/comaps/comaps/projects/21877 https://codeberg.org/comaps/comaps/projects/21877
- informal007 3mo agoTried today, I like the record track feature
- Cider9986 3mo agoI use CoMaps, it works great. You get notified in the app to download the updated maps you selected every 2 weeks or so. Could be wildly different than that, just what I notice. It's timing estimates are often 5-15 minutes off Apple Maps, which I find accurate, on ~two hour drives, but I imagine it depends on the traffic. To improve OpenStreetMap, which CoMaps uses as the data source, I use StreetComplete[1]–it puts quests around your location which ask you questions, it's user-friendly. A thoughtful feature is that it lets you download data in a location on wifi, in case you didn't want to use cellular. OpenStreetMap is like Wikipedia for mapping, anyone can contribute and improve the map, and StreetComplete is like Pokemon Go in the sense that you walk around and complete quests, except StreetComplete helps humanity, while Pokemon Go[2].... I should check to see if I can notice my StreetComplete edits getting onto CoMaps. Might be hard because they're often about accessibility at crosswalks. I've seen quests asking the number of stairs in a staircase. Seriously, is there anything they don't collect?

- gonzalohm 3mo agoDo you know if you can add hiking trails using StreetComplete? I noticed some trails are missing in my area and I would like to contribute
- an_ko 3mo agoLast I checked, not with StreetComplete. But the OSM wiki has a table of Android apps https://wiki.openstreetmap.org/wiki/Android https://wiki.openstreetmap.org/wiki/Android which column "Record tracks" can be sorted by, to see which apps have that feature. How I've done similar before is to record a GPS trace with an OsmAnd plugin, upload it to OSM servers, import it as an overlay in the web-based editor on desktop, and used that and satellite imagery as reference to draw in the missing trail. In a pinch you can also record a trace and edit directly on it in the field with the Android app Vespucci, but its UX is clunky and much less friendly to new contributors than the web-based iD editor.
- dwa3592 3mo agoDoes anyone know how fresh the business data is? like opening, closure, phone, address of businesses? i think one thing that's going for google is the network effects and what it's able to do.
- mminer237 3mo agoDepends a lot on where you live. My village is pretty fresh cuz I update it lol. My impression is that it's quite good in western Europe, might take a month in major US cities, and probably years old in most other places. I think Indonesia, Israel, and Japan are decent as well.
- seb1204 3mo agoAgreed, same here. But I don't update shops I don't support, such as tobacco, big chains.
- prmoustache 3mo agoHonestly in my experience is that in some parts of the world, or even particular neighborhoods even google maps is useless. Even for routing google maps still fail with some one way streets directions.
- maelito 3mo agoIt's as fresh as OSM databse : it depends.
- seb1204 3mo agoYou can take the initiative here.
- anyaya1 3mo agoHow is this different from OpenStreetMaps? Or does it just use OSM as its underlying engine?
- deleted 3mo ago[deleted]
- nobody42 3mo agoIts a renderer. It bakes live OSM data once very few weeks.
- gedankenstuecke 3mo agoSince a few weeks CoMaps updates its map data roughly every week, so maps are a lot fresher now (also compared to Organic Maps :))
- maelito 3mo agoOSM is mostly a db with an old website for contributors, osm.org.
- himata4113 3mo agoThis is the only app that allows you to easily add stops and permanently save paths for biking. Honestly a life changer.
- ButlerianJihad 3mo agoAs great as Waze and Google Maps are for dynamic routing and responsive path-finding, I am using rental scooters now, and at this point I really need to design some bicycle routes with intention and purpose, and Maps simply refuses to save any "dragged" or "pinned" route in any meaningful way, and I suppose this is deliberate, because A.I. knows best, kids!
- wlesieutre 3mo agoEven for driving the major apps are crappy about routes. I was on Foothills Parkway a while ago and wanted to keep Apple Maps running just as a "miles/time remaining" indicator. It can't do anything other than fastest route, with the option to ignore highways. So unless you set a waypoint halfway between every single entry/exit, it will want to get off the parkway and take US 321 instead. You can manually set up the route using a bunch of waypoints, but then it tells you the distance/time to next stop (which are arbitrary map points) instead of the distance to the end of the parkway, and you can't save the route so you'd better not touch it or want to look at anything else on the map once you have it set up.
- motoroco 3mo agoI had the same issue planning roadtrips where the journey is the destination. I’ve paid for apps like InRoute despite poor UX, inability to access my routes from desktop, and zero collaboration support I got increasingly frustrated looking for a replacement that I made https://plotalong.app https://plotalong.app in my spare time so that my wife and I could plan and save our motorcycle trips together. We still have to add the occasional “via” waypoint but it’s leagues better than Google maps at sticking to the scenic route I need to update the marketing site and get new users into the map faster, but if you want a quick way in here’s an actual trip I took last year and spruced up to serve as a demo https://plotalong.app/maps/5c735b43-cb84-5a7b-8976-2d4e0c3833d6/view https://plotalong.app/maps/5c735b43-cb84-5a7b-8976-2d4e0c383... New features and improvements come out regularly so if you have any suggestions send me a message
- KolmogorovComp 3mo agoVery good for trails
- JumpCrisscross 3mo agoHow does it compare to AllTrails in America?
- fizwidget 3mo agoUnless I’m mistaken they both ultimately use OpenStreetMap data. So, effectively the same coverage of trails. AllTrails has its whole review system sitting on top of course.
- pietervdvn 3mo agoThis is correct. Tools might however display them slightly different, have different update schedules or make different cartographic choices (e.g. not showing node networks or something)
- dopidopHN2 3mo agoGreat for hiking and sharing path. So nice to be able to do that locally and just send a .gpx file
- therealdrag0 3mo agoI tried a TON of hiking apps and this is the best free one hands down. Being able to download maps, tap to set destination, and see elevation all for free makes it top tier.
- pilina 3mo agoMapy.com does that really well [0] (not affiliated). Not open source though. It uses mix of sources - OSM included - to render map (best render imo - especially the "outdoor" layer) and they are pretty large contributor to OSM in Europe. In free tier you can have one country downloaded for offline use. Sharing .gpx is no problem. Traffic data only in Central Europe. [0]: https://mapy.com https://mapy.com
- mnicky 3mo agoTraffic info is for Central Europe plus favorite vacation destinations like Croatia and Italy. I don't know how reliable though. I agree that the outdoor layer render is probably the best there is!
- KolmogorovComp 3mo agoTangential, but does anyone know if an app exists that that the video feed of your phone with the GPS loc and reads the signs from the road and compare it to OSM to update it if necessary? Let’s be clear, in the end I use Waze for routing due to the traffic updates, but I see sometimes outdated speed limits and know OSM is one of its sources.
- nine_k 3mo agoLooks like a glue-together narrow-purpose kind of app that AI is relatively good at producing.
- raybb 3mo agoOh I don't have a link but there was a project just like this someone hacked together a while back. I think it used Gemini live or something and as you walked and scanned things it would suggest changed to the map. It was a rough demo but seemed promising. I've been wanting to do something similar but just by taking photos of menus and updating the POI with new hours/website/phone etc
- menturi 3mo agoI remember seeing something like this where it could identify signs and things, but the quality from what I recall was not great (could be way off and have many duplicates). I might be remembering Mapillary, which has a Map data button at the top left and seems to show signs [0]. I don't think it auto-updates OSM based on these data. [0] https://www.mapillary.com/app/?lat=52.4758193487485&lng=-1.8892195275168433&z=16.950002272056494&menu=false&trafficSign=all https://www.mapillary.com/app/?lat=52.4758193487485&lng=-1.8...
- Magicrafter13 3mo agoThis is what I use in my main GrapheneOS profile. I still have a dedicated profile for Google Maps though as I still have not been able to give up their greater datasets (i.e. traffic) in all cases. Decent app though. I saw someone here mention proprietary code but I wouldn't worry about it, just install the F-Droid version. That's why I use F-Droid - to guarantee I don't get proprietary blobs.
- MrDrMcCoy 3mo agoMagic Earth is fairly decent at traffic and dynamic routing. Worth the small subscription fee to keep them going, in my opinion.
- kQq9oHeAz6wLLS 3mo agoHERE WeGo does traffic, if you want to ditch Google Maps.
- pastk 3mo agoDon't worry, we have no proprietary code in all builds of CoMaps, not just F-Droid one :)
- bentley 3mo agoTo be honest, I use Organic Maps over CoMaps simply because Organic Maps is available in Accrescent (which is in turn provided by the GrapheneOS App Store), and CoMaps is not. Both Google Play and F‐Droid are just enough of a hassle (and I mildly dislike both of them) to keep me on the map app that doesn’t require either one.
- pastk 3mo agoProprietary parts had been mentioned in the context of Organic Maps - their map generator is partially closed source, and even OM F-Droid build includes some proprietary assets. In CoMaps we are serious about being 100% FOSS and this is one of the reasons we've forked from OM.
- upupupupup 3mo agoperfect timing. i was using OpenStreetMap for my ios running app and I found out that there is a cap so I ended up switching to a paid solution and have been trying to build something like comaps by downloading all the tiles
- habi 3mo ago> I found out that there is a cap A cap for downloading rendered tiles from osm.org? That exists, but is quite generous. Other (free) options are https://openfreemap.org/ https://openfreemap.org/ or https://versatiles.org/ https://versatiles.org/ to generate your own tiles.
- pietervdvn 3mo agoDon't download all the tiles, that is useless. Look into protomaps instead. One ~100GB archive for the entire world
- episode404 3mo agoIs it possible to change the maps' colors and contrasts now? Last time I checked I thought the lower contrast and washed-out colors compared to Organic Maps were a poor choice so I switched back to OM.
- pastk 3mo agoThere is an outdoor map style which is more contrast to the general/default style, if that helps.
- Groxx 3mo agoOne of the main things that keeps me from using essentially all OSM-based mapping apps as my primary is that search seems incredibly bad. I can't blend city and name, road and category, can't usually filter by features or open time, and results are almost always something like: - a result 500 feet away that sounds nothing like what you searched for - a result 23 miles away that shares one word but nothing else - a result 572 miles away that has a business name that contains exactly what was searched - ... nowhere is there an exact full-name match that is 1.3 miles away, which can easily be found by exploring the map Are there any apps that do this better? Android and desktop (e.g. linux) ideally. I'd love to use them more, but I've had endless problems using them. Good map data is kinda useless if it can't be retrieved, and trying to work around it by panning around and manually saving a hundred or so favorites really kinda sucks.
- kQq9oHeAz6wLLS 3mo agoOpen source? Not that I've found. I use HERE WeGo for searching and driving, and CoMaps for walking around.
- stevage 3mo agoTrue, although I do also have a lot of problems with Google Maps. Particularly, when I search for a small town 100km away, and instead it brings up a medium sized down in the USA. Or even more ridiculous cases, like I slightly got the name of a business wrong, so it went with a different business in the USA. Yeah, it really loves to suggest US options.
- maelito 3mo agoCould you try https://cartes.app https://cartes.app and share your search terms and expectations ? We're using Photon, an OpenSearch search engine. We've build a dictionary of place categories to help in-browser with FuseJS. Also thinking about using embeddings to complement this.
- Handrail 3mo agoCartes search and user experience was surprisingly good! Well done. I was caught off guard by having the requirement for a Bluesky account for reviews instead of something open source/federated but wasn't able to read the explanation page as it was french only, but I think the international version is still work in progress, so I'll gladly return in the future.
- nine_k 3mo agoDo CoMaps somehow support overlays, like bus routes? OSMAnd does that, but I see no such option in CoMaps anywhere (a map layer, a separate map, etc).
- pastk 3mo agoThere is a subway overlay. And there is marked hiking routes overlay being in development. There is a also an outdoor-focused map style (some people call it a layer too).
- pastk 3mo agoCoMaps project celebrated its first birthday recently! https://www.comaps.app/news/2026-05-12/celebrating-the-first-comaps-birthday/ https://www.comaps.app/news/2026-05-12/celebrating-the-first...
- Sophira 3mo agoHow does this compare with the F-Droid version of OsmAnd? [Edit: To answer my own question a little bit, I found a post from September 2025 that compares OsmAnd and Organic Maps (which this project forked from): https://blog.firedrake.org/archive/2025/09/OSMAnd_vs_Organic_Maps.html https://blog.firedrake.org/archive/2025/09/OSMAnd_vs_Organic... . I can't find anything more recent or for CoMaps specifically, other than auto-created "alternatives" pages. I would absolutely love to hear from anybody who has tried both!]
- jllyhill 3mo agoThink of it as a very stripped down and opinionated version of OsmAnd. It lacks a lot of power features, but is extremely fast and all of the options are easily available and work out of the box. So it's great for everyday use (especially in cities with a lot of POIs) but not as good for in depth travel and route planning. For example, I've used F-Droid OsmAnd extensively when planning my trip to Japan, because its guides, WikiData and Wikipedia integration are godsend for finding interesting places to visit, but used CoMaps when I was there to look things up and build routes. I'm also exclusively using OsmAnd for writing GNSS tracks because I can fine tune the parameters of measurements it captures.
- Tomte 3mo agoCoMaps starts maximally zoomed out (showing the whole world). Organic Map starts showing my neighbourhood. That‘s the simple reason I‘m using Organic Maps and not taking a fifth look at CoMaps (and I downloaded CoMaps yesterday after the HN thread).
- adamjb 3mo agoCoMaps remembers the zoom and position of your last session and returns there on launch
- pixelesque 3mo agoWhich isn't particularly helpful if you're moving around a lot. Would be nice for a preference.
- martin- 3mo agoI just opened CoMaps. The first thing that happened was that it zoomed out from my previous location in another city, and then zoomed in on my current position.
- h4kunamata 3mo agoI use CoMaps, it works like a charm on GrapheneOS + Android Auto. I have also contributed to the OpenStreetMap by adding POI and requesting logic to be changed. The only major issue which I got used to but sucks, is the search when it does not involved famous places or streets or both. Streets will be shown as minor or major and alike, I do need to use Google Maps Browser version to find the place, and the on CoMaps manually navigate to said place. But the fact that I get a map update a week, sometimes two maps update a week which other apps will take months and subscription, that alone is worth hustle.
- ponkipo 3mo agoI've read both Organic Maps thread https://news.ycombinator.com/item?id=48794446 https://news.ycombinator.com/item?id=48794446 (as it's my favorite map app I use for years around the world, and I'm an active OSM contributor as well) which quickly became overrun with CoMaps followers trash-talking about OM, now this thread appears. What I find interesting to see, and I think it's not just me who can see this - that basically every mention of CoMaps and why it is good and Organic is bad is it not only seems to be mostly written not by a regular users, but by people who contribute to CoMaps (!) - they all fail to show why exactly anybody should migrate from established app with authors who have years of experience of making Maps.Me and OM - to a basically a no-name (based on downloads) clone who is made by... "community"? We don't even know who that is, original developers and people with experience are not involved. All the talk is not about functionality of the app or anything which is actually important to users - it's all basically complaints about some kind of _internal drama_, add some misleading stuff about "dying project" or "lost community" from some commenters. So many cries about "ads" which are not actually ads but affiliate links in hotels POI which nobody clicks anyway, it's so mild it's just weird to lament about, at least I as a long time user see no issue at all. I can advise CoMaps community to focus on developing the app which can actually make real users migrate and use because of functionality, speed or other things that matter, instead of making your community look toxic because of this trash-talk. Show real improvements in comparison with OM - make live maps updates like OSMAnd, make bookmark folders with specific colors tied to it, make app barely eat any battery, make convenient and powerful interface to add data to the map - then people will move. But for now Organic Maps is totally fine and many people like me see no reason to move from it anywhere.
- patcon 3mo agoI dont know anything about this app besides your framing of "out-of-nowhere community builds an app" but am sometimes suspicious of nation states building these types of open source project forks. It's so easy now, and the cost seems incredibly low, to get into very intimate workflows (of very specific types of people). We've already seen attackers simulate whole communities for attacks on individuals, and I'm just wondering when we're going to see someone simulate a whole open source community in a longer play, as an kickstart on a longer term strategy of compromise
- opengrass 3mo agoI understand this is an Organic Maps fork without the PE rugpull.
- amatecha 3mo agoJust used it the other day while I was back-country hiking. Set some markers for some landmarks and calculated hiking distance/duration between them. CoMaps is awesome! It's also the reason I contributed to OpenStreetMaps for the first time a while ago, contributing the name of a landmark/structure up in a local mountain.
- wraptile 3mo agoWhat FOSS maps need is user generated content. For example, having "swimming spot" on my map is not really that useful - it needs photos, some description, additional information of what it actually is and how to reach it as bare minimum to be actually competitive. OSM argues that it's a "map database" but it stores labels like "opening hours" and "social media links" - why stop there? The UGC vs non-UGC debate has been the biggest crutch of all open map projects and no one managed to solve it yet.
- szszrk 3mo agoI strongly disagree. Open maps don't have to compete in this space and it would make them worse. Yes, that is something google maps excels in. Absolutely. But trying to compete here would mean they have to shift into being a social media and their biggest effort would be content moderation. There are some intermediate options here. Osmand integrates Mapilary images (I'm not a fan personally), they have travel guides built in (they became usable now, even small cities have decent descriptions where I live) and tiny things like that. On the other hand, OSM-based tools are crushing commercial maps in... being a map ;)
- wraptile 3mo ago> shift into being a social media and their biggest effort would be content moderation. I really don't buy this argument. You already have to moderate submissions - what's an extra field? Sure, UGC is more opinionated but just don't add star ratings and anything that promotes gaming of system. Just let users expand the dataset with more information, it's almost never a bad idea - isn't that entire point of crowdsourcing datasets?
- lukan 3mo ago"Just let users expand the dataset with more information, it's almost never a bad idea" Thanks for the laugh.
- szszrk 3mo ago> what's an extra field? That is not a flag "is the crossing wheelchair accessible?". It's user created picture or text. This can be any kind of content, abusive, regulated by law, spam, subjective for chat control "age verification" controls, copyrighted and so on. Moderation is a hard topic. Only very small communities can do that well.
- shekharupadhaya 3mo agoDoes it work on iOS app integration and does it has support for building application layer stuff like how MapBox sdk enables?
- mtmail 3mo agoCoMaps an end-user app, not an SDK.
- exiguus 3mo agoCoMaps is my daily. From time to time I also use it's share my location, add place or record track functionality.
- SurprisedTiger 3mo agoSeems like a minimal OsmAnd. Map rendering is nice, and crisp. Functionality really is bare-bones, though. So for example there is a metro layer - but it's subway only. No trams. I kinda need trams where I am - they're a major part of the public transport system, more so even than the metro. Problem is of course a lot of people need a lot of different things, maybe you end up looking like OsmAnd, which much as it is irreplaceable, the config/setup is a bit of an upturned spaghetti bowl.
- NoboruWataya 3mo agoI assumed the metro layer was specifically for underground lines, as they won't show up in the normal layer. I just checked for London and the tram lines and stops show up as expected in the standard view.
- drcongo 3mo agoI would love to switch to this, but the dark map is basically unusable due to the lack of contrast.
- kreco 3mo agoSorry for the slight off-topic: Is there any standard protocol/format for "layers" that could be added to such Map apps? Let's say I want to write a plugin to add my own kind of data, and then I want to export this new kind of data so that someone can import them. Or I want to create a website with my own data on top of existing one.
- pietervdvn 3mo agoThis is all OSM-based. OSM is one big pile of data - we don't do layers. It is also best to add it directly into OSM, importing data afterwards is tricky. My talk at Why25 should be a good intro (https://media.ccc.de/v/why2025-198-openstreetmap-for-beginners https://media.ccc.de/v/why2025-198-openstreetmap-for-beginne...), but the OSM-wiki also contains some valuable sources: https://wiki.openstreetmap.org/wiki/Tags https://wiki.openstreetmap.org/wiki/Tags , https://wiki.openstreetmap.org/wiki/Map_features https://wiki.openstreetmap.org/wiki/Map_features There are also various libraries to show OSM as background map on a website and allow you to draw features on top. Those support various formats (GPX, GeoJSON, ...) Leaflet and MapLibre are the biggest here, with leaflet being the easiest and MapLibre being very flexible and performant
- kreco 3mo agoThis is incredibly helpful. Thank you!
- ivanjermakov 3mo agoIf by layers you mean tiles, you can make a server providing ZXY tile images. Some OSM clients (e.g. BRouter) allow adding custom tile servers for baselayer and overlays. https://wiki.openstreetmap.org/wiki/Tile_servers https://wiki.openstreetmap.org/wiki/Tile_servers
- eric_khun 3mo agoprotomaps is also great for that. open source and straightforward
- mpawelski 3mo agoCoMaps is great! I'm still mostly using Organic Maps though, and from time to time I switch to Comaps to see the differences. In general I like the colors of CoMaps more than OrganicMaps (light theme, dark is so-so), but I still use OM because: - OM shows colors for marked trails. Pretty recent feature and not as good as in Mapy.com, but at least I don't need to switch to Mapy.com just for this feature. - recently OM added public transport routes. UX is quite bad, but it's much better that having nothing! It was quite useful at my last trip. The nicest feature that CoMaps added recently are map updates that are independent to an app update, and they try to update maps like once a week. So it's much more probable that you will have more up to date data there than on OM. So I started using it more too :)
- CivBase 3mo agoOSM is great as a map, but the biggest thing keeping me from switching from Google Maps to any OSM solution is the "white pages". My most common use case for a maps app is location-based search. Having a complete and updated registry of businesses with operating hours is the bare minimum, and OSM apps already struggle with that. I also want pictures of the establishment, pictures of the menu for restaurants, and price estimates for fuel and hotels. I understand the cost of hosting and moderating that stuff is enormous, but that's what it will take for me to finally convert.
