hrsc2isis

This program imports Mars Express HRSC files. This includes both the HRSC Stereo and the SRC instruments with processing level of "1", "2", or "3" (not "4"). The program populates all label keywords necessary to create the corresponding camera models.

For the stereo instrument there is always prefix data. The prefix data is collected and used to look for "gaps" aka missing lines. The line prefix data for HRSC files contain time and exposure duration for each line. We look for occurrences where the time + exposure duration is not equal to the next line's time to find missing lines. This program uses two passes, the first reads the PDS file into a cube, the second inserts lines where gaps were identified.

For the SRC instrument, this program reads the PDS file and converts it to an ISIS cube. The PDS file for the SRC instrument is much simpler than the stereo instrument files and requires no special processing.

This example covers importing an HRSC stereo instrument image and shows what happens when gaps are found.

Input HRSC Image	This is the raw input image, not imported with this program This image was imported with pds2isis and then exported with isis2std, in order to get a good idea of what the raw input image looks like.
Output HRSC Gap	Input discontinuity from this example This is a zoomed in region of what will become a gap from this example. Notice the features aren't aligned in the middle of the image, as if there are missing lines.

Output HRSC Image	Output image from this example This is the output from this example. The large "black" areas are NULL lines where data was missing, according to the prefix data on the raw input image.
Output HRSC Gap	A gap from this example This is a zoomed in region of a gap from this example. Notice the features on the top and bottom would not normally line up if the gap did not exist.
