Telegram Nearby Map
Telegram Nearby Map uses OpenStreetMap and the official Telegram library to find the position of nearby users.
Please note: Telegram's API was updated a while ago to make nearby user distances less precise, preventing exact location calculations. Therefore, Telegram Nearby Map displays users nearby, but does not show their exact location.
Inspired by Ahmed's blog post and a Hacker News discussion. Developed by github.com/tejado.

Every 25 seconds all nearby users will be received with TDLib from Telegram. This includes the distance of every nearby user to "my" location. With three distances from three different points, it is possible to calculate the position of the nearby user.
This only finds Telegram users which have activated the nearby feature. Per default it is deactivated.
