Please, follow this tutorial for more information.

Access to the data from Google Earth module

The Google Earth module provides a site visualization and information on data available such as types of measurements, locations, dates, etc. This interface also provides an overview of geophysical maps and cross-sections, which can be directly downloaded from the available links. Data available through predefined requests can be downloaded from this interface too.
