Wavelet Compression of MODIS Satellite Images
by
Andrew Lenharth
The Moderate Resolution Imaging Spectroradiometer or MODIS is used by NASA
for collecting images of the entire earth's surface every 1 to 2 days. 36
spectral bands are collected, for a 10.6 Mbps daytime bit rate from the
satellite. This data is fed into several series of algorithms to produce
information about land use, ocean temperature, snow pack, etc.
The 10.6 Mbps of data must be transmitted, stored, and analyzed. The size
of the stored data is huge, and is in need of being compressed. However,
any compression performed must not significantly alter the results of the
analysis.
The affects of wavelet image compression on the multi-spectral analysis of
these images is investigated.
