Hi,
You attempt to make a request using the opportunities of working with Mongo spatial data. You request geographic locations that are located in a certain neighborhood of a given point. Unfortunately, we do not support MongoDB's geospatial features.
We can offer a solution for distances up to 300 miles that is used in aviation. Here is the JS code:codefunction distance(from_lat, from_long, to_lat, to_long) {
return Math.sqrt(
Math.pow( (111.13209-0.56605 * Math.cos( 2 * ( from_lat + to_lat )/2/180Math.PI )
+ 0.00120 * Math.cos( 4 * ( from_lat + to_lat )/2/180Math.PI )
) * ( from_lat - to_lat ), 2 )
+ Math.pow( (111.41513 * Math.cos( ( from_lat + to_lat )/2/180Math.PI )
- 0.09455 * Math.cos( 3 * ( from_lat + to_lat )/2/180Math.PI )
+ 0.00012 * Math.cos( 5 * ( from_lat + to_lat )/2/180*Math.PI )
) * (from_long - to_long), 2 )
)/1.60933966531
}
console.log(distance(40.45029, -80.026184, 40.503764, -79.858034) + " -- " + "9.60");
console.log(distance(40.45029, -80.026184, 41.678638, -83.479484) + " -- " + "199.26");
console.log(distance(40.45029, -80.026184, 41.493026, -81.674572) + " -- " + "112.29");
console.log(distance(40.45029, -80.026184, 39.793372, -83.681536) + " -- " + "198.83(198.82)");

There may be a slight deviation somewhere in hundredths on separate checks.
I have done it.. Can you help me in fixing it ASAP ?
