Find latitude longitude within 100 km radius

Hi,

you can go with google places api, which returns JSON/XML, I would prefer to go with JSON bacause we have good parser (newtonsoft) available,

 

you can pass your longitude and latitude in "location" parameter,

and define "radius" as 50000 it is in meters (it is maximum for this you can not define 100KM),

you will need key to call this api, which you can generate from google developers console.

 and endpoint for this api is

https://maps.googleapis.com/maps/api/place/nearbysearch/output?parameters

 dig more here https://developers.google.com/places/web-service/search?hl=en

 

and accept solution if appropriate

 

Thank you!
