title: How to find the nearest points to given coordinates
body: <p>How do i identify if a point with a <strong>LAT, LONG coordinate format</strong> is near to other point.</p>
  
  <p><em>Lets Say i want to find all the points near to</em>:</p>
  
  <p><code>-38.9086621 ,-68.082214
  </code></p>
  
  <p>That are at less than 1km of distance. I already know how to find a coordinate in a given quadrant but not how to find a quadrant near a point.</p>
