Display file. .las directly in Google Earth

Is it possible to view files. .las on Google Earth?

The answer is simple: Your application is created las2kml other. So let's create it. For this purpose the former is understood as is a kml file. We open Google Earth and mark a line. (The example is done in Segovia, my hometown following his well-known aqueduct)

Creating a route

Saving file kml

If we open the kml file:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">

</kml>

But we can reduce it to the minimum expression as:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">

<LineString><altitudeMode>absolute</altitudeMode><coordinates>
    -4.118265,40.948473,1000 -4.118266,40.948474,1000
   </coordinates>
  </LineString>
 </Placemark>
</Document>
</kml>


From here you just have to create the new kml file.

For this purpose we chose a small file .las:

3D Appearance Lidar Sample File

There was to be reduced to only 20,000 points for not blocked Google Earth and the result is this:
