Maps.Me coordinates encode

[ghost]

Hello! I'm Michael.

I'm searching for a way to encode coordinates in Maps.Me format to create custom links. And there's no information about from Maps.Me at all.
Could you help with that? I checked your decode ge0 URL code and hope you could help me with it.

Thanks a lot!

Hello.
Please see mapsme/omim#6386.
The current version of the core ge0 routines is here: https://github.com/mapsme/omim/tree/aab28bc72ec3baf1ffb7588dd93375cb6604fcba/ge0

@mpimenov, Thanks a lot!

But why the accuracy of longitude is so low? It always truncates it.
How can I solve this?
I give to function latitude: 50.2662864 and longitude: 28.6859482. But throw decoder I take:
latitude: 50.26629,
longitude: 28.0,

All tests passed.

What you see looks like a type error somewhere (longitude seems to be converted to integer), probably you are using a wrong implementation.

Our library at https://github.com/mapsme/omim/tree/a1a15b4c4d8b922ee69588bf99c8650b319ab5b9/ge0 works correctly in your case as shown by the test above. This is the only implementation that is supported by us.
The repository where our discussion takes place (https://github.com/mapsme/ge0_url_decoder) is obsolete and not supported.

Your coordinates encoded by our library at zoom 19 result in the "ge0://84To-til2K" string.
Here they are properly decoded: https://maps.me/ge0?latlonzoom=84To-til2K

Thank you!
I used wrong function on the delimiter. Now everything works!
