smigen VS l3mapgen?
Posted: Wed Jun 07, 2017 4:29 pm America/New_York
I've been using smigen for years (and years and years). I have a very large collection of mapped l3 files created with smigen that I use for various different analyses. I understand that smigen has been (or is in the process of being) replaced by l3mapgen. I just did a quick test in which I used both programs to map a binned chlorophyll file that was created using l2bin. The two relevant lines in the script I used are below.
smigen ifile=${INFILE} prod=${2} ofile=${ofile1} resolution=${resolution} latnorth=${latnorth} latsouth=${latsouth} lonwest=${lonwest} loneast=${loneast} meas=${stat} stype=${stype} precision=${precision}
l3mapgen ifile=${INFILE} product=${2} ofile=${ofile2} resolution=${resolution} north=${latnorth} south=${latsouth} west=${lonwest} east=${loneast} oformat="hdf4"
I'm attaching a scatter plot of the chlorophyll values in ${ofile2} (the l3mapgen output) versus those in ${ofile1} (the smigen output). Although many of the points fall on the 1:1 line (as one would hope), many do not.
Why??? Does this mean that if I intend to use l3mapgen going forward, I need to reprocess all my binned files that were created with smigen with l3mapgen if I want them consistent?
Thanks.
