in Trip to JIAFS
On November 5, 1999, a group of faculty
from the School of Engineering and Applied Science traveled to Hampton,
Virgina to visit the Joint Institute for the Advancement of Flight Sciences
(JIAFS). JIAFS, which is located at the NASA facility on Langley
Air Force Base, is a joint GW-SEAS/NASA institute that has been in business
for more than 25 years. About 150 full-time students study at JIAFS.
In edition, the institute undertakes a large research project jointly with
NASA, other federal government agencies, and federal contractors.
A significant part of the NASA operation
(and therefore JIAFS) involves environmental and energy management applications
of remote sensing and high altitude imagery. These include:
Agricultural Applications. To
determine crop and vegetation types and conditions, to measure crop acreage
in all parts of the world, to model crop yield forecasts, and diagnosis
of crop stress, including disease, insect infestation, and nutrient deficiencies
- Forestry Applications.
To identify and analyze forest types, cut units, stand ages, streams,
roads, and other boundaries. These information helps for planning future
cut blocks, post-harvest regeneration, planting, construction of roads,
and managing pest or fungus infestations. Potential uses are mapping
and monitoring wetlands, soil erosion, forest fire with possible hazards
and studying environmental impacts.
SEAS Faculty at the JIAFS
Fisheries Applications. To complement
observations made on ship-borne from the sea surface. These observations
can help in characterizing environmental factors that affect fish habitat.
Insurance/Disaster Management Applications.
For forecasting severe storms and floods, landslide probability, land condition
changes, drought/crop failure, beach erosion, among others.
In addition to discuss JIAFS programs, the
faculty members held a meeting of the SEAS Research Advisory Committee,
chaired by Professor Shahram Sarkani.
- Transportation Applications. To provide
a major addition to GIS (Geographical Information Systems) databases
used for transportation planning and construction. These include improving
aviation forecasting, analyzing surface construction, mapping road networks,
analyzing urban growth, and managing inland waterway logistics.
