Subject Distance between 2 points Lucene Spatial
Date Mon, 22 Dec 2014 05:35:39 GMT
Dear All,

We are using lucene spatial strategy to find out the distance between a pair of Lat/Long.

Given a pair of Lat/Long I need to find the near accurate distance between these 2 points.

I have used Haversine, LawOfCosines and Vincernity however unable to decide which will provide
the best output(accurate output).

There is not just 1 point but millions of points which will need to be passed into against
 a set of point to find the closest point.

Which might be the best approach. Additionally, I observed from the API, that the output of
these 3 algorithms are in Degress. Is there any API in lucene which can return the output
in double,long,int etc. formats.
