Question: How to optimize processing many L1 files into GeoTIFFS (l3mapgen)?

Re: How to optimize processing many L1 files into GeoTIFFS (l3mapgen)?

Good to know re: l2gen bounds. I'll just omit it.

Is atmospheric correction relevant for SST or can it also be omitted in that case?

I figured that I could use the L1/L2 browser for manual filtering for clouds but was looking for a programmatic option. That will work though.

Thank you.

How to optimize processing many L1 files into GeoTIFFS (l3mapgen)?

Hello, I'm preparing to process several years of MODIS Aqua L1 data into high resolution (250m) true color GeoTIFF images for a visualization/mapping project. Before I process the whole dataset I want to make sure that I've optimized each step. Here's how I'm currently generating an image: modis_GEO...

Re: How to create a TrueColor image?

Thank you - I was able to generate a TC image using these commands... `modis_GEO A2013208173500.L1A_LAC` `mapgen --ifile A2013208173500.L1B_LAC --geofile A2013208173500.GEO --use_rgb --oformat tiff --resolution 1km --projection mercator` Am I correct that this command will generate the highest possi...

Re: How to create a TrueColor image?

Thank you for your reply. I'm running `mapgen` and got an error: "Unrecognized HDF-EOS file A2013208173500.L1A_LAC" I downloaded the input file from here: https://oceancolor.gsfc.nasa.gov/cgi/browse.pl?sub=level1or2&per=CU&day=19095&prm=TC&set=10&mon=19052&sen=amod@...

How to create a TrueColor image?

Hello, I'm a new user trying to learn how to use SeaDAS and the command line tools create a highest possible resolution TrueColor image (and later an animation) such as this one: https://oceancolor.gsfc.nasa.gov/gallery/feature/images/A2014270171500.GulfOfMaine.jpg. It seems like reproducing a TrueC...
