A dramatic view of Hurricane Gustav is shown in the Coastal Online Assessment and Synthesis Tool (COAST) geobrowser being
developed at NASA’s Applied Sciences Program at
Stennis Space Center. COAST is being used to integrate
previously disparate coastal datasets from NASA and other
sources into a common desktop tool that provides new
data visualization and analysis capabilities for the coastal
researcher. Built upon the popular NASA opensource
World Wind geobrowser from NASA Ames Research
Center, COAST allows direct data import and overlay
of accessible online geo-image and vector datasets,
temporal image overlay animation, and transparency
control over the data layers. The image depicted on the
cover is a COAST view of Hurricane Gustav as it bears
down upon the oil and gas infrastructure laden coasts
of Louisiana and Texas on August 31, 2008. NASA
Moderate Resolution Imaging Spectroradiometer
(MODIS) 500-meter resolution Blue Marble imagery
with bathymetry from NASA’s Jet Propulsion Laboratory
forms the background image with a NASA Aqua
MODIS visible truecolor image of Gustav superimposed
(image courtesy of MODIS Rapid Response Project at NASA Goddard Space Flight Center).
Overlaid vector data includes oil industry infrastructure from the National Oceanic and Atmospheric
Administration and the 2007 population density by county from the U.S. Census Bureau.
Tasselled Cap parameters were derived for the SPOT5 sensor
from different seasons and geographical locations; differences
were observed in the Greenness and Wetness parameters
while the Brightness was proven relatively stable.
A novel approach for automation in roof extraction from aerial
images based on the assumption that roofs are composed
of several spatial polygons, and automation in extracting
these polygons can lead to automation in roof extraction.
Classification-trees were used to map forest types and forest
type groups for the conterminous United States and Alaska
using Forest Inventory and Analysis data.
Investigation of the confounding effect of understory contributions
to satellite-derived estimates of LAI on two loblolly
pine (Pinus taeda) plantations (ages 19 and 23 years) located
in Virginia and North Carolina, USA.
Testing the suitability of AWiFS imagery with TM as a benchmark
for deriving row crop focused cover type maps over
highly cultivated regions of the central U.S.
A complex building model, which includes a mixture of fl at and
sloped planes, is simultaneously reconstructed using a coarse to fine approach accomplished by recursively partitioning an
initial building region with data-driven linear features into a set
of convex planar polygons having maximal co-planarity.
