Hello fine folks, experts!
I have only one question which bugged me for a while. Regarding the three-dimensional terrain images by TC camera stereo view data: How do they obtain elevation data for the areas which are "hidden" completely by shadow? There is no useful pixel information which can be correlated, is there? Or do they have additional elevation data available to complement the missing data (e.g. laser ranging)? I have been reading quite some stuff about digital photogrammetry lately (which I find very interesting btw) but this remains a mystery to me. Anybody who can literally shed some light into this, please do so. Thanks a lot |

Hi FordPrefect! (and thanks for all the fish! ).
Obviously is impossible to make stereography or photoclinometry for completely dark regions, however Kaguya has anoboard laser altimetry... http://www.selene.jaxa.jp/en/equipment/lalt_e.htm your friend Arthur Dent. -------------------- I always think before posting! - Marco -
