Heh, Google is catching up. I want to highly recommend https://www.komoot.de/plan for hike or bike planning. It's fundamentally based on OSM and very very nice.

That's great. For Melbourne, Australia komoot is offering sensible bike paths that google maps never does.

Thanks for sharing

What's neat here is how clean their elevation data seems to be. Having spent a long time trying to work with various dataset like the NASA SRTM and USGS files, I quickly came to realize how hard it is to clean up this data. Looking at this feature I tried out a couple of things that would have tripped up a naive implementation and Google Maps seems to have dodged the most obvious pitfalls. For example a bike route th…

it looks clean, but from the few routes i checked it might be clean because it's been fuzzed beyond the point of usefulness. it's got no scale on it so i can't be sure what exactly is being showed, but there's a couple major hills near my house (and i mean major, i live in the mountains) that don't even register.

Six years ago, I spent an hour learning to drive manual transmission in my friends car. I did not get very good in that hour. Then I went and bought a manual transmission car of my own. The drive back home from the dealer was one hell of a trip. I learned very quickly how tricky it is to get a car moving when you're stopped on a hill. So I totally could have used this back then. :)

Oh man. I learned to drive in my parents' automatic mid-sixties Impala, so when when I bought my first car - a yellow 1969 Toyota Corolla - I wanted an automatic. The salesman said, "You know, this is just a two-speed automatic, and it doesn't perform very well. I really think you'd be happier with the stick shift." I told him I didn't know how to drive a stick shift and he said, "That's no problem, I'll teach you."

So we drove a few lurchy blocks around San Francisco - yes, San Francisco, the city of seven hills. Ah, if it were only seven!

After a while he said, "Doing great, drive me back to the dealership and you're on your own."

I knew my way home, but I couldn't remember where the hills were.

I could have used elevation data that day...

"...sweat beading upon his brow, he might recount that Damp Morning when he drove his Manual Transmission up the Impossible Grade, and was forced to stop, just below the top! In frantic pantomime, he’ll pull the emergency brake and disengage the clutch. Crane his neck to peer anxiously at the car sniffing his downhill bumper. Bulge his eyes. Gun the engine. Pop the clutch. Release the brakes. Lay down some rubber with a piercing squeal. Float his steed slowly onto the flat. Wave the smoke from his eyes. Pump his arms in brief celebration. And finally, grouse about that sadistic driving instructor who got him into the pickle in the first place. What a jerk!"

I think they must be using sensor data from GMaps. Yesterday I mapped a ride that said mostly flat. It was not after riding it with Google Maps giving me directions while on the route. Today it shows an incline of 504ft. Same destination, same origin just two different days.

Now if only they'd put terrain mode back.

It's accessible if you put 'terrain' in the search box (and I see a text button for it). I couldn't get it to work together with a bike route.

The link disappears if you're zoomed in too closely.

Yeah, bought my first car from a town about an hour from my home, a manual car. On the drive home I learned to drive a manual. That weekend I learned to change a clutch :-)

It also doesn't work for some of the major bridges that I ride over.
