title: Latitude / Longitude and meters
body: <p>I have a small algorithmic problem.</p>
  
  <p>I am developing an Android application. I get GPS coordinates. For example: latitude: <code>23.23907</code>, longitude: <code>50.45786</code>.</p>
  
  <p>So I get a point. I want to compute bounds details on this point plus or minus 5 meters. I.e.:</p>
  
  <pre><code>[23.23907 - 5 meters ; 23.23907 + 5 meters]
  [50.45786 - 5 meters ; 50.45786 + 5 meters]
  </code></pre>
  
  <p>How to make this calculation?</p>
  
  <p>Thank you very much!</p>
