Working with the Data
Opening NASA HDF5 Files
HICO HDF5 files are compatible with NASA SeaDAS 7.0 and higher software. With some scripting, they can also be opened using programming languages such as Fortran, IDLTM, and MATLAB®, and in atmospheric correction programs such as Tafkaa (NRL), ATREM (Atmospheric Removal Program, University of Colorado), and FLAASH (Fast Line-of-Sight Atmospheric Analysis of Spectral Hypercubes).
General File Properties
The data are stored in NASA HDF5 format.
More information about the contents of HICO HDF5 files can be found on the Data Characteristics page.
Scaling the Data
The user must apply a scale factor to the data to transform them to appropriate units before use.
- Launch SeaDAS (7.0 or higher).
- To load a HICO file, use File > Open Product from the main menu.
Using MATLAB programming language
Sample matlab code is available demonstrating how to work with HICO HDF5 data in the MATLAB programming language. This code loads the data, creates a true-color (RGB) image, and plots a spectrum.
Using an HDF5 reader
Various tools for opening and viewing HDF5 files are available from http://www.hdfgroup.org/downloads. These tools allow you to see inside the files and find the names of the various datasets.
