As the title states. I really want to like and use open source maps, but it seems that whatever database they are pulling from is pretty bad and incomplete overall. You also have to put the exact name, as it is in the system, otherwise it will not come up.
Just to use a really simple and well known example, after downloading the appropriate maps for this search, if I search for "the liberty bell", the first four results are either roads or businesses near me, then the liberty bell museum in Allentown (which btw is permanently closed), and then the liberty bell center, then the liberty bell center again for some reason, and then finally the actual liberty bell itself. There are also suggestions down the list that no longer exist, such as the liberty bell pavilion. So this is clearly outdated data that is being used.
The suggested searches are also nonsense, only taking the last word into account, i.e suggesting "belles ave", "bellgrove rd", etc, rather than "liberty bell center", which would be the most logical suggestion for that search.
Why is this so bad, and what needs to happen to make it better?
Community data like OpenSteeetMap rely on voluntary submissions, so the data can be either obsessive-level complete or non-existent. Especially businesses don't put themselves on OSM so their location/name/info are somewhat old or just don't exist
Search algorithms are incredibly complex to make it work well, Google (the king lf search engines) has likely hundreds of people working on an algorithm, Apple the same way
Offline search is also very taxing even if tue app implemented such algorithms, google maps searches with their billion dollars servers
None of that is true anymore. Fuzzy searching is incredibly easy, you don’t need billion dollar servers, and there are open source libraries that do it right out of the box. It has nothing to do with community submissions and everything to do with how they implemented search.
What’s most likely is that they don’t have a ranking system for each poi, so liberty bell just defaults to whatever is closest rather than whatever is most likely.
https://en.wikipedia.org/wiki/DWIM is hard even for other humans sometimes.
I don't know much about the topic, but I guess even if that's the case, it's likely most open source projects just don't have contributors knowledgeable or willing to invest the time
Yes of course that is the underlying reason, for example i contribute to a lot of open source projects and even if i have the expertise on any given thing i can only put my knowledge in so many places at once. And not only that but interests wax and wane and oss contributors get shit on quite often.
I can't find the link from my phone, but there is a website for adding your business to OSM. It has options for things like the business name and opening hours. That could be helpful for surveying businesses and adding them to the map yourself, just ask the business owners for the details.
If I can find the link later I'll post it here 👍

That's the one, thank you 🙂
Just to confirm #1: moved to another city, and pretty much any address within the city is now searchable and correct. POIs are a bit off, but I try to update them.
Some places publish address data with a compatible license, some even directly importable to osm. But e.g. here where I live, we got an official address list for each residential addresses (no offices, factories, etc.), but without coordinates. So we can only use it to check if we still have to survey something.
The biggest open address db I know of is openaddresses, you can see on their coverage page it's a hit or miss if they have data: https://batch.openaddresses.io/data#map=0%2F0%2F0
Another address source list is on the Overture maps attribution page, you can see in some places they don't even have country wide sources, they had to ask from city level governments: https://docs.overturemaps.org/attribution/
Openaddresses shows my county as green, but my area only has block-level addresses in OpenStreetMap. What's up with that?
They may only have that block level addresses. Or simply no one imported that data to osm yet. Or maybe its license is not compatible with ODbL, the license of OSM. There may be a lot of reasons, the easiest was to know it is to contact local mappers and ask them, you can find your local community here: https://openstreetmap.community/
You know, that's like the third time I've been given that exact advice. I just really don't want to make a whole new account on Slack or whatever just to talk to OSM people.
Use the forum then, you don't have to register, you can login with your OSM account: https://community.openstreetmap.org/c/communities/us Most top mappers usually follow multiple channels.
So what you're saying is, if I want an actually functional map, I have to use Google or apple?
If you're on Android, try GeoShare, it allows you to share location from Google Maps to CoMaps, so you could easily use CoMaps for navigation.
You can also use GWMaps
Very neat, thanks for sharing! I just gave it a test and it works perfectly.
Interesting, thanks!
It's up to you to define "functional" based on your use case. If you are unhappy with the current state of Comaps or other open source map apps, then of course you are free to use Google or Apple.
Edit just to expand somewhat: For what it's worth, I find Comaps great for my use case, so it is more than "funcional" for me. That's what I was getting at.
I would prefer to get away from Google, and don't have an iPhone so apple is not an option atm. Looking into it a bit more, and I am learning that it's a community built map from OSM, so I am understanding why it is the way it is. I will work on contributing and customizing it to my liking.
Contribute with money or your time. Google spends gazillion of money on maintaining their map data, on osm only several thousand people, mostly volunteers work on it WORLDWIDE.
With comaps you can report problems you find on the map, I frequently solve issues in my area reported by comaps users.
Another option is that there are several other navigation apps on Android: MapQuest, Magic Earth, Sygic, HERE WeGo, TomTom GO, MapFactor. I don't know how they compare, but I've seen them offered as non open source Google Maps alternatives. But yes, contributing to the community maps data is awesome if you can.
Frankly, they all suck, a LOT compared to Google Maps. And I don't particularly like Google Maps functionality (let alone their draconian data gathering).
I really, really want to use something more open, and I've tried every app you've listed. I even own a lifetime license for CoPilot.
No one has a search that compares to Google in any meaningful way, so I have to use GMaps for search. If I have to do that, I may as well just use GMaps even though it sucks in it's own ways.
I really want to not use GMaps, but there really aren't any competitive products (and I have seven mapping apps on my phone I keep trying, they just all suck).
I get that. It's difficult to beat Google's money. Have you tried the app someone suggested elsewhere on this thread that lets you search in Google Maps but get the navigation from one of the Open Street Maps based apps? Maybe that would provide a decent compromise.
Onomatopoeia@lemmy.cafe
I am quite satisfied with Magic Earth.
Not at all. I love Organic Maps/Comaps and I think in many aspects including usability (GM is trash to navigate and drains batteries like hell), it's much better than GM. However, when I want to reach a place I either find the address online, or search on google maps and then navigate to it with a better, lighter, offline, more beautiful app.
I'm just saying that open source maps usually are heavily lacking on the search functionality, and that's sad but understandable.
