[Geysers] Google Earth imagery updates

[caverns]

The Google Earth development team has announced an update on its
15-meter base imagery. The software is now using imagery from
TerraMetrics/TrueEarth instead of Landsat. Most of Yellowstone is not
affected since the much of the park already possesses
higher-than-15-meter-resolution data. However, for Geysernaya
(Russia), El Tatio (Chile), Iceland, and New Zealand, I have noticed
significant improvements. Sulphur Bay at Rotorua, New Zealand, is
particularly striking with the new imagery.
