Nice one, Doug - look at the cloud shadows! If the sun elevation is known the cloud height can be calculated.
Phil -------------------- ... because the Solar System ain't gonna map itself.

Well from plugging the average time given for the image (2004-11-23 16:11:22) Latitude (20.2913N) and longitude (-230.7915W) into mars 24 I get a Solar Elevation of 53.7deg and Solar Azimuth of 279.9deg if that's any help. |

Hmmh - I measure about 62 pixels between the clouds and their shadows in the middle of the picture. According to the metadata the resolution is approx 90.9m/pixel. With the above solar elevation I get an altitude of around 7.67km above the surface (where the shadow is) for those clouds. |
