For CoastWatch Files
CoastWatch AVHRR satellite image files, which contain image data, coastline and lat./long.
graphics, and header information, are compressed using a special compression format.
Thus, a program is
needed to decompress the image data and separate the other information for use
with the imagery. Once decompressed, the images are converted to 8-bit raster files and
can then be displayed
CoastWatch provided software (or any image processing software). A number of computer
programs have been developed for both PC, UNIX and MAC workstations, which facilitate the
use of the AVHRR sea-surface temperature and albedo imagery. These are also available on
the CoastWatch ftp site (ftp.glerl.noaa.gov in directory "coastwatch").
- CoastWatch Software Library and Utilities v3.2.3 Tools (CDAT)
The CoastWatch Software Library and Utilities is a package of software
tools for working with NOAA CoastWatch satellite data. The utilities
allow data users to easily manipulate and visualize satellite data in both
the new CoastWatch HDF (.hdf) files and the older CoastWatch IMGMAP (.cwf)
files. The utilities are composed of both graphical and command-line
The core software functionality:
- Render data and legends to PNG, JPEG, PDF, and GeoTIFF images.
- Export data to raw binary, text, or ArcGIS grid files.
- Convert from older CWF format to CoastWatch HDF.
- Obtain information on file attributes, dimensions, and variables.
- Manually apply navigational corrections.
- Perform generic math operations, including cloud masking.
- Calculate data statistics: min, max, mean, standard deviation.
- Combine multiple data files into one composite file.
- Perform data sampling at discrete Earth locations.
- Perform satellite data registration to a common master region.
- Generate graphical dataset coverage maps.
- Support for rendering line and polygon data from ESRI shapefiles.
- Support for transparency in graphics overlay colors, useful when rendering "highlight" polygons.
- Log enhancement scaling in CDAT for use in chlorophyll plotting.
- GIF image output in CDAT and cwrender.
- Support for AVHRR NOAA 1b version 3 files.
- New tool for automatic navigational correction using image data.
- Improved manual page documentation and command-line usage notes via "-h" option.
- Bug fixes for CDAT in PDF and image rendering code.
- Updated icon set and Unix/Linux look-and-feel.
- Updated code for cleaning up partially written files after command-line tool failure.
- On Windows/Linux/Solaris, Java is now included in the download
- On-the-fly units conversion in CDAT
- Support for latest NOAA 1b data including MetOp
- Reformatted and more accessible help system
- Faster application startup
- Full screen data display mode
- Support for NOAA 1b files with scan line gaps
- Navigation error analysis panel in CDAT
- Support for NOAA KLMN 1b format AMSU and MHS data files.
- Improved support for GRIB 2 format files.
- Improved performance when working with large ACSPO and CoastWatch HDF swath data files.
New features in the 3.3.0 b54 release include:
- New 64-bit support for all operating systems
- Read support for NetCDF 4 data with CF-1.4 metadata (experimental)
- Command line rendering options for adding water marks and custom color palettes
