This is a very unofficial Google Earth Mapping Tool to process a volcanic ash advisory to make it viewable in Google Earth.
Pressing Get Latest will check for the latest Volcanic Ash Advisory from London and Process it. It is possible to cut and paste another VAA into the upper text box, other that the current one and process that instead.
Pressing Process will generate a Google KML File suitable for use in Google Earth, based on the VAA in the upper text box.
Download Last System Generated VAA Google Earth File, not the one created by processing on this page.
