Node GeoMatch

Filter a JSON dataset to return only records located within a given radius from a given point.

What does it do?

It loads a list of JSON records containing geographical coordinates ({"latitude" : "X", "longitude" : "Y", ...}) from a given file.

Then checks whether every record in this list is included within a given radius from a given point.

It assumes that the earth is a sphere of radius 6370km.

It eventually outputs in the console a list containing the records matched (included in the specified area), ordered by an ID property (user_id) in a ascending fashion.

Usage:

• run it: node program.js
• run tests: node geolocation.test.js
  • the file empty.json is for test purposes only

Requirements:

• NodeJS
