You'll need to simply make a basic kml document with a bunch of
placemarks representing each point. For each placemark translate your
intensity into a color value of your choosing represented by the
<color> tag in kml. You'll need to have a intensity to color
transformation and just for loop your way through writing out each
Placemark tag...basic construct..
