parsing CSK stripmaps
Added by Jacqueline Tema Salzer over 9 years ago
quick question:
has anyone succesfully parsed CSK stripmap data with the latest version of the software?
It works fine on my machine with spotlight data, but runs into a problem with stripmaps:

It may also be an issue with my h5 libraries? I wonder because the Spotlights work fine... Any hints would be appreciated.
Thanks,

So, issue resolved:
I realized the stripmap and spotlight data is actually not delivered in the same format by ASI, as the stripmaps still need to be focused.
You can do this in Gamma (MSP) using the script RAW_TO_SLC_CS. In my case the SLC_FORMAT had to be set to 0=FCOMPLEX rather than the default, and then went fine
