HRSC level 3 images

ISIS version(s) affected: latest

Description

The hrsc2isis program does not support level 3 images.

But level 2 images are no longer in PDS, it appears. At the link https://pds-geosciences.wustl.edu/mex/mex-m-hrsc-3-rdr-v4/ there are only new images that are level 3. Previous versions have been archived, per their release notes.

I was able to use hrsc2isis with level 3 by simply changing 3 to 2 in the .img file.

Maybe this tool can be revisited to accept level 3. Here's a recipe that shows the current workaround: https://stereopipeline.readthedocs.io/en/latest/examples/hrsc.html

To add, it appears that PDS still offers raw (non-mapprojected) HRSC images, but for some reason their img files shows "level 3", which appears to be interpreted by pds2isis to be mapprojected, perhaps. Here's a sample file: https://pds-geosciences.wustl.edu/mex/mex-m-hrsc-3-rdr-v4/mexhrs_4000/data/1995/h1995_0000_s23.img

@oleg-alexandrov This is something we have run into and should be able to address

Has this actually been pushed to release? Doesn't seem to be working as of ISIS 8.1.0.

For a bit of clarification here the ESA planetary science archive describes the processing levels as follows:

@ballisticfox This fix is under the 8.3 release. Please see the changelog for release infomation. 8.3 is currently an RC. See ISIS conda versions here for downloading.
