Google Earth^® allows creating KML files, that may be used to show point locations, line arrays, polygons or bitmaps on top of Google Earth´s satellite image surface.This is a very easy way of showing sample locations, "georeferencing" (or maybe google-earth-referencing, since the georeferencing of the GE satellite images is not always precise) a geological map or just showing a friend where you live or where the BBQ tonight will happen...

example GE screen

simple kml - file

multiple placemarks in one file

defining buildings in a kml file

overlay maps on Googles Earth

fix if kml-files from your server do not open in GE

watch and play route in Google Earth

fix if Google Earth does not connect  to server

example screenshot for the below KML file for a simple placemark.
by default GE will zoom not only to 9.33 km eye alt as shown her but further down to 1 km which is too much for the resolution of the bora-Bora picture in GE. By the way, the water in the Bora Bora lagoon really looks like that
:-).

you can either download it from the link or copy and paste the lines into the Windows plain text editor (Notepad) and save it as borabora.kml (not borabora.kml.txt.... switch file type from text files to all files in the save as window).

If you have Google Earth^® installed, double clicking on borabora.kml either from this server or from your computer should open the program and display the screen on the left.

<kml xmlns="http://earth.google.com/kml/2.0">
  <Placemark>
   <name>Bora-Bora Airport</name>
   <Point>
     <coordinates>-151.752044,-16.443118</coordinates>
   </Point>
  </Placemark>
</kml>

Leaving out all optional stuff this is a minimum file to display a standard icon and a placemark name at a certain place on (googles) earth and center the view on it. Without a view height (range) GE zooms very far down (1 km).
