Software Features

The CoastWatch Utilities let users work with earth science data created by NOAA CoastWatch / OceanWatch. Users can easily view and convert data in various formats: HDF 4, NOAA 1b, and NetCDF 4. The software has both interactive and batch processing tools. The functionality includes:

  • Information and Statistics - File contents, statistics computations on variables (for example min, max, mean, standard deviation), direct access to raw file and variable attributes.

  • Data Processing - Data format conversions, compositing, generic variable math, data sampling.

  • Graphics and Visualization - Interactive visualization/analysis, batch image rendering, ancillary graphics creation such as data coverage maps, grids, coastlines, land masks.

  • Registration and Navigation - Resampling of data from one projection to another, interactive generation of region masters, manual and automatic navigational correction, computation of solar and earth location angles.

  • Network - Data download and server status.

The CoastWatch Utilities are available for Windows, Linux, and Mac OS X.
