HDF4 OPeNDAP - Demo

This demo is for testing the new enhanced OPeNDAP HDF4 handler which is still under active development. The OPeNDAP HDF4 handler can be configured in two ways --- with --enable-cf option or with both --enable-cf and --with-hdfeos2. The benefit of using --enable-cf option allows users to view remote HDF4 data using CF-convention compliant OPeNDAP client visualization tools like IDV. However, turning on such option has many limitations.

• NASA Data

The demo data we're using are NASA EOS data like AIRS and MODIS. Since these data files are huge, please use DAP constraint expression when you test data retrieval. For Grids, most OPeNDAP clients like IDV, GrADS and Panoply will work with the demo servers that are configured with --enable-cf (and --with-hdfeos2). For all Swath demos, only IDV works. For the MODIS Swath, IDV works with the demo server that is configured with both --enable-cf and --with-hdfeos2 only.

Default	With --enable-cf	With --enable-cf and --with-hdfeos2
AIRS Grid | Swath MODIS Grid | Swath	AIRS Grid | Swath MODIS Grid | Swath	AIRS Grid | Swath MODIS Grid | Swath

A collection of screen-shots from various OPeNDAP client visualization tools. Since most of them require CF-convention, you need to turn the --enable-cf option on inside the handler.
