Re: Recompiling SeaDAS processing C source code

I doubt there is any reliable shortcut -- just follow NASA's instructions. If you stick with the same compiler versions NASA uses you should not encounter the problems that arise using different OS's. The build uses CMake, which does rather extensive checking to for the required libraries and header...

Re: Recompiling SeaDAS processing C source code

As I need to run SeaDAS processing SW with some modifications, for research purposes, I'd need to modify some C source programs and recompile l2gen executable. Is it possible to get somewhere the makefile or any other instruction to recompile l2gen (or all the SeaDAS processing executable)? See: ht...

Question: Extract L1A MODIS SeaDAS 8.1.0 OCSSW

Re: Extract L1A MODIS SeaDAS 8.1.0 OCSSW

Using these in the extractor on the L1A file appeared to work, but when processed up to L2, it's the wrong region (and must be over all cloud). Even if it had worked that way, the approach sort of defeats my objective to reduce processing time and disk usage by subsetting prior to processing L1B/L2...

Re: SeaDAS 8.1.0 installation error

https://seadas.gsfc.nasa.gov/requirements/ says MacOS distributions include a suitable Java JRE, but that may be outdated. A recent JRE such as the one in the link you mention will be widely used, so any Big Sur problems should be found and fixed. SeaDAS uses the SNAP Java GUI, but ESA SNAP support...

Re: (Log file directory is not accessible to write) Install Seadas 8.1.0, WSL, Windows 10, OCSSW

I also have ESA SNAP installed on my Window 10 system. For SeaDAS 8.1, saw the "log file directory is not accessible to write" message once. Using the Help menu sent me to the ESA SNAP log directory: %HOMEPATH%\AppData\Roaming\SNAP\var\log I found the SeaDAS 8.1 log file directory at %HOME...

Re: PAR L3 product - Unexpected patterns

Gniwiii, thank you for providing the link to the anc data. It seems the primary sea ice product is NSIDC0081. Could this mask the resulting PAR product because it fails in this area? Also, I am not sure this is what you are implying, but the square-like patterns are much larger than the NSIDC0081 s...

Question: l2bin/l3bin/l3mapgen distortion for non-standard data product

Re: l2bin/l3bin/l3mapgen distortion for non-standard data product

It still isn't clear to me whether the problem is that l2bin mishandled a 64-bit array or you stored a 32-bit array but labelled it as 64-bit data. The latter seems more likely as the dimensions of the array would be smaller by a factor of 2. Remote sensing often uses 32-bit arrays for geophysical d...

Re: l2bin/l3bin/l3mapgen distortion for non-standard data product

Hi, I just wanted to update on this if anyone in the future comes across a similar issue. As gnwiii commented, if l2bin/l3bin/l3mapgen are working, the problem isn't with the xml file where I added the new product/algorithm. Following gnwiii's suggestion, I used gdalinfo to inspect the netcdf l2 fi...

1) "Did you try to run install_ocssw in Windows?" No, I din't. 2) "You can start the SeaDAS GUI using the Windows Start Menu or from a command line. These can give different environments." I start the SaaDAS GUI using the Windows Start Menu 3) "You need to understand the pu...
