SeaDAS and Some Notes of SeaDAS 5.1

The SeaDAS (SeaWiFS Data Analysis System) is a software that designed and written for the specific purpose of analyzing and processing SeaWiFS HDF data.

SeaDAS is a comprehensive image analysis package for all SeaWiFS data products and ancillary data (wind, surface pressure, humidity and ozone) from NMC (National Meteorological Center and TOVS (TIROS Operational Vertical Sounder). All SeaDAS source code is free and available for download via FTP.

Below are some notes correlate to SeaDAS5.1 version that often appear in its forum:

Announcement

  • Support for Fedora Core 6 and CentOS 4.4.
  • New msl12 Version 5.6.6
  • New geolocate, l2bin, l3bin, and smigen programs.
  • New Aqua and Terra LUTs.
  • l2bin program supports 500-meter MODIS processing.
  • l3bin program can subscene by latitude/longitude.
  • msscanpixlimits improved for MODIS GEO support and handling of extracts.
  • When displaying MODIS L1A and L1B files every band containing data is now available to be selected for display.
Before installing SeaDAS, delete or move any previous versions of SeaDAS and also disable any lines in your shell initialization files that set up the old SeaDAS environment (e.g. "export SEADAS=OLD_PATH_TO_SEADAS", setenv SEADAS OLD_PATH_TO_SEADAS", "source OLD_PATH_TO_SEADAS/config/seadas.env"). Do not install a new version of SeaDAS "on top of" an old version.


Problem of Installation SeaDAS 5.1 on Fedora Core 7 and Fix it

The first problem is that IDL 6.n for n <4>
There a news that IDL 6.4 was not working on Fedora 7 yet. For this preoblem, we can do command-line stuff, but idl hangs (and needs ctl-\ break out) if you try to use graphics. So, next better if you try RSI tech note 3092:

chcon -t texrel_shlib_t /usr/local/rsi/idl_6.1/bin/bin.linux.x86/*.so

and the kernel.randomize_va_space = 0 setting.

There could well be bugs/features in the driver for my old ATI mach64 graphics (which did, however, work for SeaDAS starting with FC2).
