title: Add Lines To Google Earth Using KML
body: <p>So, basically, I'm trying to figure out a way that I can draw lines (say, representing the flight path of an RC plane or something) onto Google Earth using KML.  Here's the kicker though: I want to give it an initial location, and then check somewhere to see where to continue drawing the line to, draw the line, and leave it be.  Once it's done, I could then move it around.</p>
  
  <p>Ex: </p>
  
  <ol>
  <li>Starts at a point A in google Earth</li>
  <li>Checks File XYZ.kml on //someserver</li>
  <li>XYZ.kml has updated coordinates to draw to</li>
  <li>Google Earth pulls in those coordinates and extends the line</li>
  <li>Repeat 2->4 until complete</li>
  <li>View completed flight path from 3rd person.</li>
  </ol>
  
  <p>Does anyone have any ideas on how to do this?  It seems like it can change the location of a model or something in this fashion, but you would have to watch it first person.  I haven't been able to figure out how to get this particular functionality to come out right.</p>
