Some time ago I started replacing all services and apps that I use with FOSS altnernatives. Most of them were easy to replace but some corpo/big-tech apps had ecosystems too advanced to be conveniently replaced. For example, substituting Google Maps on Android (or I guess Apple Maps on iOS) was a bit of a struggle as the most popular FOSS alternative app was OsmAnd. First of all mad respect and huge kudos to OsmAnd team of contributors but for me the UX was overwhelming and too customizable which is probably a huge bonus to power users but IMO that makes it very unlikely to become a large scale alternative to Google maps. Probably other people realized that too and some 6-7 months ago CoMaps was released, a FOSS app that is also based on OpenStreetMap layer but this time with a simplistic and smooth UX/GUI.

In case somebody is not familiar with OpenStreetMap (OSM) - basically it is a non-profit org, but its heavily maintained by community members and anybody around the world is allowed to contribute and enrich map content. Even if org can theoretically get corrupt I think anybody can make a fork and continue with community contribution. Creating an account is easy, you could start contributing in like 3 minutes. A huge number of services and apps are basing their map layers on OpenStreetMap, such as CoMaps above.

The quality of OpenStreetMap/CoMaps/OsmAnd is as good as the contributions to it are - so the more people use it - the better and more content it will contain. I would like to invite everybody to give it a chance and use https://www.openstreetmap.org/ on desktop and CoMaps on mobile devices. You should have enough motivation to abandon Google or Apple products, but final piece of motivation is that eventually Google Maps will start censoring content (like Reddit or Instagram) or just share your location history to ICE or perform some other serious violation like that (like Microsoft did recently).

CoMaps has a really nice and simple interface where you can add missing places (business, community services, recreation areas etc) while OpenStreetMap on web browser allows to update anything you imagine (e.g. see a missing street? Add it. A new building was developed - just add it!). If everybody enriched only their local neighborhood with features on the map we could really build something beautiful. Existing layer probably already contains 90% of the stuff you'd ever search for as contributors really did a outstanding job throughout all these years. But that additional 10% makes a real difference for it turning into a much bigger scale tool, and this feels like the right time to kick that off.

It is important not to get demotivated that not many people maintain and contribute as your neighborhood might remain a lonely detailed places for years. OSM existed for a long time now and is very likely to keep existing for decades to come, everything that you update or create remains a legacy that stays forever saved in the map (unless somebody further updates it). Perhaps, in 20 years time people will be grateful. And to tidy up and make max out of your neighborhood you really need one weekend or so.

For example, in my local area I've started adding location marks of recycling bins, dumpsters, parking lots, playgrounds, pathways, building tunnels and monuments, but also I've added missing shops and updated working hours and websites for shops that existed.

Also #1, be responsible when making changes, don't overwrite other people's work unless it is an improvement. Double check everything that you add, and also if you don't have any experience with map editors or GIS software take a watch of some OSM editing tutorial.

Also #2, I most likely omitted some other useful FOSS tools, and it doesn't matter which one you decide to use as long as it is based on OpenStreetMap or any other community driven layer.

Also #3, tell all your friends and family to do the same.

Yeah, this might not be the most important thing to cure the world at this moment but developing community-driven mindset where everybody takes a small or big part in it is the way to go. Cheers!


EDIT: Amazing input in the comments, I'll try to summarize additional suggestions provided by other people. Thank you for pointing out URL errors in my post too.

Very useful suggestion by illusionist:

We need more wikipedia images and content, there is still a lot to improve on maps just by contributing to wikipedia. Osmand added custom buttons and now you can enable wikipedia connections with one click which is great

If that's the only way you're going to contribute to OSM, by all means, go for it. But as a desktop OSM editor, I really dislike some of the incentives pushed by mobile applications. Primarily not adding objects as polygons (as it would be difficult to draw on such devices), but adding them as POIs (parking, amenities, etc.) and paths (waterways for instance: where paths are often used for just naming, or as water"ways", like for marine traffic). This often leads me to correct these changes, as they really stand out compared to the rest of the map. So generally, I view these tools as complementary, rather than final changes; unless it's changes to POIs or something, which is where these applications shine, in my opinion.

I think there's something to your point of view, however, these apps do get more people contributing precisely because they remove some of the friction to add and correct information.

In my case, I just add or correct things on streetcomplete, and then add or correct polygons on my computer at osm when I can.

As developer of https://mapcomplete.org/ - I cannot allow contributors to edit geometries. If I did, I'd have to show all geometries in the vinicinity, which would make it way more confusing for a non-technical user.

Even then, geometry cannot always be exactly determined (e.g. shops in a mall). And some communities even agree to never use geometries for some types of POI!

[–] jjlinux@lemmy.zip 1 points 6 hours ago

Never heard of this before. Looks pretty cool. Allowed for a more focused scenario to contribute. I'll take it for a spin.

[–] PierceTheBubble@lemmy.ml 1 points 18 hours ago (1 children)

Editing geometries is hard enough as it is on the desktop (especially with glued points), so I can't imagine making such changes on the mobile. I think it's best to not allow editing geometries, and to leave such changes to devices better suited for the task.

[–] pietervdvn@lemmy.ml 1 points 4 hours ago

It really depends on your scenario. In some African countries, access to both laptops and internet is rare; but phones are ubiquitous. Vespucci really shines there, even if it less user friendly then say iD (which is not useable in such a scenario)

[–] UnGlasierteGurke@feddit.org 3 points 22 hours ago (2 children)

so i should use StreetComplete only to add or correct data for stuff that already exists?

[–] PierceTheBubble@lemmy.ml 3 points 18 hours ago

Oh, you can add new things, that's perfectly fine. I still prefer mobile users adding features, even if they are of an unusual object type; effectively being another type of fixme to desktop users. But instead of another desktop user integrating these elements, I rather have mobile users on the desktop as well; as to integrate their mobile changes when at home. If you're sightseeing, these applications are very helpful, for creating/editing POIs and effectively sketching out non-POI features; but the latter does require some work to integrate them.

Streetcomplete is deliberately a tool for quick and easy editing. You can add notes there, and desktop users can fix them for you in an editor with more features. You can add images to notes to describe the problem. You can subscribe to new notes in an area with an rss reader, so I check new notes every few days in my city, solve them if they contain enough information.

If you want more powerful editing options on mobile you can use Vespucci.
