Hello, I've written a couple of Python scripts to assist (us, at least :wink: ) in using SeaDAS.
One converts a CSV file into a placemark file, and the other will unpack a Landsat 8 bundle and rename the files to the "old" scheme, allowing use of the Collection 1 files in SeaDAS 7.

Hello,
Thank you for sharing you script! I am trying to use convert_OLIbundle_from_C1.py on an image I downloaded from GloVis. However, I got the error message that there is no MLT.txt. Note that I first gzipped the directory that I had downloaded from GloVis, as it was in tar format. See the procedure I implemented and error message below. Can you help me in resolving this issue? Thank you! Alice

Dear Alaric,
Thank you so much for you reply. It works now! ... but I am running into another issue: after I converted my images with convert_OLIbundle_from_C1.py, I processed it with L2gen in SeaDAS. It outputted the file "L2016038160136.L2_LAC_OC". I would like to visualize this image into SeaDAS, but I get an error message when trying to import it:

Hi Alice,
I'm glad you're able to unpack the bundle now!
Believe it or not, I've not yet gotten around to trying to run "l2gen" on Landsat. We've only done some low level work with OLI data... We have exported geoTIFF images, using the File-Export->GeoTIFF menu item. Try both the "GeoTIFF" and the "BigGeoTIFF" menu items and see if one wokrs better for you than the other.
Perhaps you can start a new thread asking for help with level 2 Landsat processing to get someone with some expertise to help you. I'm sorry I can't offer more for that problem...
