HDFLook

HDFLook is a tool for visualizing and analyzing HDF and HDF-EOS files. HDFlook is designed to recognize different MODIS HDF-EOS files.

Documentation on HDFLook is available at the HDFLook download site See README, the documentation 'tar' bundle, the HDFLook Manual in English and in French (gzipped PostScript files).

Installation

Pre-built binaries are provided for Intel PC running Cygwin, Linux and MacOS-X, including PowerPC using X11. README provides installation instructions.

If HDFLook is NOT a part of the Msphinx package, then the user has to download the MAPS.tar.Z file to get the map and font files.

At the first use of HDFLook, the user has to define two environment variables with:

• - the absolute path of the directory containing the coast and river map data files.
• - the absolute path of the directory used by temporary files.

For example, in csh:
