The Information Technology component of SGE designs and builds software
and hardware tools to transform Earth observation data into information
products, available over standard internet protocols.
These data processing and modeling technologies include instrument design,
parallel processing techniques, graphic vizualization tools and network-enabled
decision support agents and subsystems.

Progress
in ecosystem science and advances in remote sensor technology are mutually
dependent. On an agency-wide scale, newly deployed sensor platforms
such as those developed under NASA's
Earth Observing System (EOS) program are enabling surface observations
on regional and global scales that have not been previously attainable.
However, there are additional needs for specialized sensors that meet
unusual requirements for specific missions. Such sensors are typically
designed to satisfy stringent criteria that are not attainable with
the large-scale general purpose sensors provided by EOS. For example,
sensor packages having low weight and volume are required for deployment
on small aircraft, unpiloted air vehicles (UAV), and small satellites.
Sensor data handling systems enabling near real-time acquisition and
processing of images are required for response to natural hazards. Some
missions require sensors having unconventional spatial and spectral
characteristics.

Engineers and Technicians in the Ecosystem Science and Technology branch utilize
a number of communication and telemetry systems ranging from relatively low
bandwidth unlicensed, to high bandwidth satellite links. Systems developed
include 9.6Kb command and control links, encrypted WiFi data delivery systems,
and recently, encrypted Ku and Ka band satellite links, allowing over-the-horizon
command and control and data translink and delivery worldwide.

Airborne
and space-borne science platforms for deployment of Earthobserving sensors
have been primary tools for ecosystem science research. Facility platforms
available to the general research community are frequently used Ames
Airborne Sensor Facility and agency-wide platforms developed under
NASA's Earth Observing System
(EOS) program. Additionally, developmental platforms having unusual
capabilities have much potential for advancing ecosystem research (ERAST
program, UAV-FiRE demonstrations.)
