I have a problem when projecting ocean color level 2 product. The ocean color data is stored in one hdf file which contain many bands including sea surface temperature etc.
I use MRT Swath tool and open the file but I couldn't find ocean color band in available bands for projection. I can see all the other bands like sea surface temperature, but only ocean color are not shown.
Do someone have experience in this? I tried also using ENVI but the result is not good. Using MRT Swath tool for sea surface temperature give a good result of projection.
Please your advice. Thank you in advance.
Our sea-surface-temperature products are stored in separate
level-2 files from our ocean-color products. If you want ocean-
color products, you must download the ocean-color files.
Our ocean-color files have names like, A2011306055500.L2_LAC_OC,
while our SST files have names like, A2011306055500.L2_LAC_SST
I got the data from my colleague who do processing to MODIS data. The file has a name like *.seadas.hdf, so I guess that he uses Seadas or part of it. Might be I'm mistaken.
In that file, sst and ocean color are stored as bands. That's why I use other software for projection.
Do you have experience with MRT Swath Tool? While I will also try to install Seadas software by myself.
Thank you for your answer.
If you read the documentation on the MODIS Swath Tool
you will find that it "... was designed specifically to accommodate projection of LP DAAC MODIS swath products. Its success on
other data types (such as level-1B radiance data and certain atmospheric products) is somewhat coincidental and in no way guaranteed. "
So, it was probably just luck that it recognized our SST product. SeaDAS can read (and reproject) all of the files we produce.
Thank you so much for your note. I think I will try SeaDAS. I finished downloading it and ready to install.
Thanks to all.
