Comprehensive Examples

This page provides comprehensive examples on how to access and visualize various NASA HDF/HDF-EOS files using IDL ^®, MATLAB^® and NCL. Other tools and programming languages examples can be found here.

Please read this special note first before you proceed further.

For a list of examples for the different data centers, click on the examples in the table below.
