HDF Explorer Update and demo

Published on

HDF Explorer is a data visualization program that reads Hierarchical Data Format files (HDF, HDF-EOS and HDF5) and also netCDF data files.HDF Explorer offers a simple yet powerful interface for the visualization of HDF data. The data is just a click of the mouse away. Data is first viewed in a tree-like interface, and then optionally loaded and visualized in a variety of ways. HDF Explorer features include fast access to data, grid, scalar and vector views. It also allows exporting your data either as a ASCII text file or a bitmap image. HDF Explorer supports HDF5 dimension scales.
