IMG to PNG GOD Group: Moderator Posts: 2250 Joined: 19-February 04 From: Near fire and ice Member No.: 38 |
I'm updating my IMG2PNG utility to correctly convert LROC images to PNGs. The NAC images now get correctly converted except for one problem: Image orientation. Does anyone know how to determine from the embedded labels or the index.tab file whether an image needs to be mirror-flipped?
From LROCSIS.pdf (page 3) in the documents directory: QUOTE ...This orientation requires that one of the NAC frames from a NAC-L and NAC-R paired observation must be transformed such that both images have the same ground orientation" At first I thought I thought this was simple, i.e. that the NAC-R images needed to be mirror-flipped but apparently things are more complex: M102443238RC.IMG does not need mirror-flipping whereas M114185541RC.IMG needs to be mirror-flipped (unless I've managed to get myself totally confused). |
