title: GPS intermediate points
body: <p>I'm developing an algorithm that involves inserting intermediary points between GPS coordinates. To be precisely let's assume that I have these 2 coordinates:</p>
  <blockquote>
  <p>25.60593,45.65151</p>
  <p>25.60662,45.65164000000001</p>
  </blockquote>
  <p>I want to add extra points between these coordinates (on the same &quot;line&quot;). Is it wise to consider a linear variation (in this case I consider the intermediate points as points on the segment defined by the 2 given coordinates).</p>
  <p>This involves actual GPS data obtained from a computed route -&gt; this would mean that the distance is less than 1000 meters between each consecutive shape point (on highway the distance between consecutive points can be quite big due to the fact that it is a straight line).</p>
  <p>Is linear variation a good approximation, or are they any other methods? (given the fact that the distance between points is <strong>less than 1km</strong>)</p>
  <p>Thanks,</p>
