Our project goal is to develop software to access HDF5 data via OPeNDAP software framework. OPeNDAP is a software framework that simplifies scientific data transfer, allowing simple access to remote data. Local HDF5 data can be made accessible to remote locations by using this OPeNDAP HDF5 server. Existing data analysis and visualization applications can be transformed into OPeNDAP clients that access remote HDF5 data served by OPeNDAP HDF5 server.
We have implemented an HDF5 data handler so that general HDF5 data can be served via OPeNDAP. In particular, we added the support of using the existing OPeNDAP clients to visualize NASA HDF-EOS5 Grid data. We believe that the server can help researchers, scientists, educators, and the general public visualize and analyze HDF-EOS5 data via existing DAP clients. The source code of the handler has been released by OPeNDAP.
The following movie demonstrates how HDF-EOS5 grid data can be visualized via HDF5-DAP data handler by DAP client IDV. The data is HDF-EOS5 AURA OMI Level 3 Grid data. It shows the ozone concentration level over the south pole from August 31, 2007 to November 9, 2007.
