I wish to use Google Earth to visualise and explore 3D atmospheric density data. In my case it is ionospheric electron density, which is a niche area, but I can imagine this might have been done by someone to display say atmospheric moisture content or pollution levels (or volcanic ash plumes??).
I am new to KML files, but reading over the developer guide it isn't obvious how best to go about this. Would you slice your 3D density data into many 2D layers and use < altitude > elements? Or would it be better to use grid the data into many small cubes and use < polygon >s? Or some other option?
I'm sure this has been done before, but I couldn't find any suitable examples.
