Imports a PDS4-formatted CaSSIS image into an ISIS-formatted cube.

Overview Parameters


The application, tgocassis2isis, takes a PDS4 formatted Colour and Stereo Surface Imaging System (CaSSIS) image and outputs an ISIS cube from the image data.

Note that the corresponding .dat file containing the image data must be placed in the same directory as the XML file in order for this program to work as intended. Furthermore, this program is specific to CaSSIS formatted image data.

Below is an example of part of a CaSSIS XML label for one of the images that this program is capable of importing. It is vital that the XML label that is being imported has its labels formatted the same way in order for tgocassis2isis to work properly.

            <comment>CaSSIS specific XML header</comment>
              <scaling_factor> 1.00</scaling_factor>
              <value_offset> 0.00</value_offset>


The following table provides the nominal specifications for each of the 4 CaSSIS filters. Updated measured values may be available from the mission team.

CaSSIS Filter Nominal Specifications
Name Wavelength (nm) Equivalent Bandwidth (nm)
PAN 675 250
BLU 485 165
RED 840 100
NIR 985 220
