Description

When I mosaic map projected JunoCam frames into a single observation, the lighting geometry is lost. Since these images are all acquired during the same observation, the normal behavior of automos and other mosaicing programs should not apply. We know these data are all acquired at essentially the same time and with essentially the same geometries, so we should be able to query the lighting and etc. geometries.

History

#1 Updated by Moses Milazzo 2 months ago

Note: I understand that this capability was removed early in the development of ISIS3, when multi-frame or multi-CCD instruments were uncommon. The issue is that such instruments are becoming more common. Currently, instruments which acquire multiple data streams at the same time or in close sequence include:

  • THEMIS VIS
  • HiRISE
  • CASSIS
  • JunoCam

The mosaics of observations from these instruments should not lose photometric information. We know exactly how these observations are put back together from their constituent parts; this is entirely different from mosaicking images from multiple orbits or flybys.
