Time to check out Cartes.app! https://cartes.app/?clic=34.02076%7C-118.50899
It uses OSM and has some very useful routing options for foot/bike/public transportation.
Damn, you computer nerds are amazing. One of your coordinates is SPOT ON. ๐ฏ
Cartes.app is amazing.
It excels at route planning but then it encourages you to use comaps for the actual navigation. Because its offline.... its a beautiful opensource ecosystem
Just tried it out and I don't like that they presume to judge whether I should use a car or not. Like sorry I live so close to an Ikea, should I move further away so you sanction me using a car for moving furniture?
Showing the co2 emissions, gas prices etc is cool but making a tool and then enforcing your ideals on how it should be used is a bit too far
Oh I hadn't realized it shows CO2. Cool.
What did it do to judge you? Does it give a sad emoji or something?
Just tried it for the 1 hour drive I need to make tomorrow: "no door-to-door itinerary found".
Manually switch to public transport: the same, it then proceeds to try add cycling to the route and gives up when it can't find any routes that include up to 4 hours of cycling. Assuming people are able to spend 4 hours cycling time- or healthwise in itself is completely bonkers, but OK.
Guess there's really no alternative, show me the route by car: it gives me the route while letting me know "cars destroy living conditions in our planet and ruin our cities". Yes too bad, that's why I did my best to find a feasible solution to that problem. Why rubbing this in if you can't even provide me with an alternative?
I'm a left voter, the environment is an important topic for me. But this "high and mighty" shit rubs me the way. It doesn't help and only causes pushback from the public we want and should try to reach. Especially if you just told the user they are shit out of luck if they don't want to take the car.
Ha, it actually says that? Yeah having a dumb pop-up is pretty heavy handed. If there was a train as an alternative then I get it. The app seems to be under heavy development. When I first saw it it didn't have much outside of France, now it covers much of Europe... maybe you are outside of what is covered well.
Thats a little disingenuous that it only shows the CO2 impact of the cars.
https://ourworldindata.org/travel-carbon-footprint The above data doesnt consider manufacturing or infrastructure polution for the given mode of transport.
Should be noted that OpenStreetMap relies on volunteers to map their surroundings. So it can be quite inaccurate, depending on where you are
But that also tells you to help out and get mapping! It's surprisingly fun. And with apps like StreetComplete you can help out supplementing existing data in a very easy way
I can't tell from their site -- are they using a service like GraphHopper or Valhalla for routing, or have they rolled their own? If they're doing a limited amount of public transport routing, fuel efficiency calculations, etc, I guess it's the latter?
The project is open source: https://codeberg.org/cartes
They combine a bunch of different services and list them all out here (unless you speak french, you'll want to translate the page): https://cartes.app/verso
Looks like they're using Valhalla for routing as well as MOTIS/Transitious, Node-GTFS, GRAZE, and Transport.data.
Thanks! I was wondering whether I'd get any benefit from their routing versus GraphHopper's web UI; sounds like right now, that'll just be in parts of France.
That app told me to leave the main road and go on a dirt road
That looks like you have it set for cycling. It defaults to a "Safe" mode which would likely take you on alternate paths that are less travelled by cars. At the bottom you can change the route option to "Road" or "Balanced". If it still wants you to take a dirt road after selecting "Road", then it's a problem with OpenStreetMap.
You can fix those issues by going to openstreetmap.org then zoom in on the area and edit the map. Make sure that the main road exists all the way through and that the dirt road is tagged with
highway=track.Its a fun offroad adventure, scenic route for sure. Just go for it, all gas no brakes! (Watch out for golfers, flying golf balls, sand traps, golf carts, etc)
shit, I'm actually fine using Organic Maps, but I love PWAs too much to not install this
