ZoneDetect

This is a C library that allows you to find an area a point belongs to using a database file. A typical example would be looking up the country or timezone given a latitude and longitude. The timezone database also contains the country information.

The API should be self-explanatory from zonedetect.h. A small demo is included (demo.c)

The databases are obtained from here and converted to the format used by this library.

Online API

You can test the library using an online API: https://timezone.bertold.org/timezone It takes the following GET parameters:

  • lat: Latitude.
  • lon: Longitude.
  • c: Set to one (c=1) to produce compact JSON.
  • s: Set to one (s=1) to get only the timezone.

For example: https://timezone.bertold.org/timezone?lat=51&lon=5
You are free to use this API for any application, but I am not responsible for the quality of service. Please contact me if your application requires reliability.

Demo

An online demo is available here: https://cdn.bertold.org/demo/timezone.html. Simple click anywhere on the map and see the result of the query.
