And the practical application of data like these: https://prehrada.hrach.eu/en.html

And the more sinister application of this kind of map is for programming optimal paths for cruise missiles.

This, however, makes it easier to get funding. If you want money, create military, banking or casino/betting applications.

Very nice! Obligatory and shameless self promotion everytime the topic of 3D maps comes up: I recently created a web app to visualize GPS tracking files in a 3D terrain. You can upload your GPX or FIT files and it generates the 3D Terrain using Babylon.js It's called https://cubetrek.com

Is there anyway to get such track or map from Apple Fitness?

Very cool! But when trying stuff like this I'm always reminded how flat things look at scale, hah. Like my bike ride to work the other day: https://cubetrek.com/view/8197 200m of elevation from kilometer 25 to kilometer 31, but hard to grasp how steep some of those hills are, haha.

But for hiking mountainsides, or where I specifically bike up steep hills it looks really great https://cubetrek.com/view/8203

Awesome - since I was a kid I always dreamt with something like this but for the cities I know, because I thought that would make it easy for videogames to use them to set stories. Playing GTA (or other videogames) on my own city would be an incredible experience.

I like to use mapy.cz when looking at czech republic, because they're veeery recent. Only problem I have with them, is that they are intentionally uncompatible with leaflet. They have their own api/map library and for some reason prohibit usage with other map libraries, because (as per their docs, api.mapy.cz) they believe that accessing their maps directlly is some kind of abuse? Other than that, it's a good product.

I recently created a web app to visualize GPS tracking files Off topic, but since you work with GPS tracking files, perhaps you can recommend a GPS tracking device for me. Until last year, I used one I got around 2005 that was about half the size of a pack of cigarettes. You turned it on, and it would start logging waypoints at 10 minute intervals to a standard text tracking file on a microSD card. I could unload tha…

I personally use a Garmin Fenix (an old one, Fenix 3). The watch form factor is perfect for my use cases (mainly hiking, running and ski mountaineering).

Also: the barometric altimeter is a must have for mountaineering purposes.

I guess it very much depends on what you need it for.

Garmin Etrex.

Discontinued, according to https://www.garmin.com/en-US/p/6403

The only available Garmin alternative is $200. The one I'm replacing was $30. But I'm willing to go to $75.

Also, it's a bit large because it has a screen, but that's not a deal-breaker.

The one I'm replacing didn't even have a screen, just a light for power and a light to indicate it was connected to the satellites.

I don't use Apple Fitness, but I assume there's a way to export GPX files?
