Producing cloud and land mask files in SeaDAS

Hi Danny,

I meant I was trying to generate level2 files (Rrs) but I also need to export cloud and land masks as separate geotiff files for post processing.

L2gen processing for 10m Sentinel 2

Thanks Sean! Is there a way to resample in SeaDAS with little effect on the image quality. I used other tools for resampling but my image quality was affected.

L2gen processing for 10m Sentinel 2

Hi All,Please how do I output 10 resolution images from Sentinel 2 using the l2gen. I noticed the default output resolution is 20m, but I need 10m.I used something like the command below but still getting 20m output? Or do I need to resample the output elsewhere?Any hint will be highly appreciated.l...

Sunglint flag in seadas

Thanks Bryan!

Are those pixels masked out by default, or I need to use the flag to mask such pixels from the entire scene?

Sunglint flag in seadas

Hi All.
Please what is the threshold for sun glint masking in SeaDAS (in the default exclusion flag). Not sure if it's SWIR(0.005)?
Thanks.

What does outband_opt mean for l2gen processor for Landsat 8

Hi All,

Wondering what the outputband_opt option means. I used it to process Landsat-8 images and discovered that for some sites, using the zero option adds to more negative Rrs retrieval (for example at 443 nm).

Thanks for your anticipated response.
