I-7: Data compression techniques and computer telecommunications:
satellite and weather databases – Dr. H. Kroehl (NOAA, US)
Presentation abstracts will appear here as soon as possible.
Satellites monitoring
the Earth and the Earth's environment are generating huge volumes
of data at an ever-increasing rate. At the same time scientists,
educators and the general public seem to have an insatiable appetite
for environmental data. High speed networks and new protocols
are helping but are still unable to keep up with demand.
This session will focus
on two alternative solutions to large numbers of data transfers
of very large data sets, i.e. data compression techniques and
computer telecommunications. Current techniques allow for large
data compression ratios without a significant loss of information,
especially for environmental satellite imagery. Alternatively,
automatic sharing of data between computer systems can transfer
demand from routes with higher traffic and limited bandwidth to
routes with less traffic and/or greater bandwidth like research
and engineering networks. Talks in this session will demonstrate
techniques to address the problems associated with increasing
demand for rapidly expanding databases over networks with limited
capacity.
The areas to be discussed
include:
- No loss data compression
techniques
- Losey compression
techniques
- Wavelet transform
compression techniques
- Meteorological satellite
imagery and products
- Earth Observing
Satellite (EOS) imagery and products
- Virtual data centers
- High speed research
and engineering networks
- Data management
for remote numerical modeling applications
