This is a demonstration of various data visualizations that we have made using a combination of Matlab, the free tools in the OpenEarth toolbox, and the Google Earth TM mapping service. To make your own, just sign up and check out the tutorials for the googleplot toolbox. In an NCK 2012 paper we have shown that plotting data into Google Earth is possible for a wide variety of coastal datasets.
A few of the other *.kml files with which the screen shots below have been made are available in this (temporary) open dir. Note that some of the bigger files might need a bit of time to load, just be patient.
There are more initiatives worldwide that offer data in Google Earth.
