Perhaps this is related to the direction in which the HiRISE strip is captured? Some have North up and some South up. That information is present in the .LBL file. I don't think it is possible to determine it from the file name.

Perhaps this is related to the direction in which the HiRISE strip is captured? Thank you Paolo. I am aware of this "image flip", I believe it is not it. I really do not know what is causing it, but several of the PlanetFour:Terrains project's volunteers (myself included) are heavy users of the viewer. It is quite handy to view the CTX in context in order to find near ones and overlaps. The CTXs used by the project are from the south pole area, so we were surprised to be taken to the north polar area! Fernando |
