Question: Seadas T2022.2 modis_atteph and getanc issues

Re: Seadas T2022.2 modis_atteph and getanc issues

There is a sea ice concentration band contained within the SST ancillary file, so this replaces the NSIDC file. Going forward, the program getanc will return the SST file for both the sstfile and icefile parameters and will not return the NSIDC file for the icefile parameter.

Question: Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0

Re: Mismatch between input geographic limits and output of l2gen for MODISA using V2022.0

Please post the exact file name you are using. Also if possible post your par file ... or cut and paste the subsetting options which you used. For example I just ran l2gen on file: AQUA_MODIS.20101010T180500.L1B.hdf # SUBSETTING OPTIONS north=40 south=35 east=-70 west=-75 The resultant file had the ...

Question: l2gen processing
Replies: 4

Re: l2gen processing

When you choose a suite in l2gen it applies the values in the particular suite parameter file. So for example for modis the suite files are: IOP: $OCSSWROOT/share/modis/msl12_defaults_IOP.par GSM: $OCSSWROOT/share/modis/msl12_defaults_GSM.par OC: $OCSSWROOT/share/modis/msl12_defaults_OC.par etc. You...

Question: Sentinel-2 MSI

Re: Sentinel-2 MSI

This doesn't fully answer your question, but striping can be band/detector specific. You are showing Rrs_443 whereas the true color image you mentioned uses the 490nm, 560nm, and 665nm bands.

Question: Spectra in SeaDAS GUI
Replies: 4

Re: Spectra in SeaDAS GUI

The Spectrum Plot is for single pixels. You can place pins and run it for all the pins and you will get a spectral line associated with each pin. So one line per pixel. If you don't use pins then it monitors the pixel directly beneath the cursor. So unfortunately it doesn't do what you want regardin...

Re: Spectra in SeaDAS GUI

When you draw a vector box layer on a SeaDAS loaded image it creates an associated mask. This mask by default will be called "geometry". To do statistics on this "geometry" region of interest, use the Statistic Tool (Menu > Analysis > Statistics) Check the "Use ROI Mask"...

Question: Transferred mask goes in folder Bands - SeaDAS 8.1.0

Re: Transferred mask goes in folder Bands - SeaDAS 8.1.0

One additional thought. The xml file export is for masks of type "MATH" and not of type "GEOMETRY". If you are trying to import a mask based on geometric coordinates then you can do this with a ESRI shapefile. For a given scene file, to export a vector as a shape file, in File Ma...

Re: Transferred mask goes in folder Bands - SeaDAS 8.1.0

Hi Oliver, I just tested this in SeaDAS 8.1.0 and it works fine. I can export a mask from one file and then import it into another file. In my test, the mask in the 2nd file gets loaded correctly into the masks folder and not the bands folders as you mentioned. So I cannot replicate your bug. Can yo...

Re: I have problem about extracting multiple NetCDF files with multiple stations of interest

There's a tool called Pixel Extraction in SeaDAS. I think it's a bit hidden, but you can find it by typing "Extract Pixel Values" in the search area of the SeaDAS GUI (top right corner of SeaDAS). The Pixel Extraction tool let's you enter the input files, and specify the coordinates for yo...

Question: Correlative plot
Replies: 5

Re: Correlative plot

The Correlative Plot tool has a ROI mask checkbox. So you use this to specify your ROI mask(s). Note that this is ROI (region of interest) and not a flag masking selection. The best approach would be to create a new quality mask via the Mask Manager, which is to be treated as a ROI mask. You can the...
