Probablistic Mapping of Global Vegetation Structure Using Lidar
ICESat/GLAS,
MODIS, C#, PostGIS, ENVI, IDL, ArcGIS, Manifold.NET
|
Estimated vegetation height for the Southeastern US, realized from probability distributions
gathered from satellite-based lidar data (dissertation project, in progress).
|
Locating Urban Trees Using Lidar
MASSGIS lidar data and orthophotos,
C#, PostGIS, KML, Manifold.NET
|
Results of tree-finding algorithm displayed in Google Earth
with extruded building footprints, both based on Lidar data.
|
Transpiration from EVI and Temperature
MODIS EVI/LST products, C#, PostGIS, Manifold.NET
|
Transpiration in the Northeast US estimated from
regression equations derived from flux tower measurements,
satellite-based enhanced vegetation index, and temperature.
|
Daily Northern Hemisphere Snow Depth
NSIDC EASEGRID products, C#, MatLab, IDL, ArcGIS
|
Daily snow depth for 2002-2009 interpolated from weather station
data (Cryospheric Processes and Remote Sensing Laboratory).
|
Biomass Burning
MASSGIS orthophotos,
Landsat imagery, C#, ArcGIS, Manifold.NET
|
Animation of forest consumption by proposed
biomass generators (Mass Forest Watch).
|
Lidar / Thermal Mapping
MASSGIS lidar and orthophotos,
Landsat imagery, C#, PostGIS, Manifold.NET
|
A map of the urban thermal landscape in suburban Boston showing the
correlations between land cover and urban heat, based on Landsat and lidar data.
|
Aster Inventory
ASTER imagery, C#, MatLab, PostGIS
|
A Google Earth KML interface for browsing ASTER satellite images of supraglacial
meltwater lakes in Greenland (lighter means less meltwater; border color is month of
year; altitude is year) (Cryospheric Processes and Remote Sensing Laboratory).
|
Landsat Interpolator
Landsat imagery, MatLab
|
Utility to interpolate pixels missing from Landsat ETM+ imagery.
|
Modeled Versus Measured Sea Ice Extent
NSIDC EASEGRID products,
EDGCM, C#
|
Left is polar view of NIC January 2003 ice chart; center is model output monthly
average for January, 2003; right is difference image.
|
Cellular Automaton Rule Extraction
C#
|
A system for encoding and traversing the "rule space"
of cellular automata models extracted from daily West Nile
Virus risk rasters (CARSI).
|
Quadtree Index
C#
|
A quadtree-based raster comparison metric for binary
images that measures their similarity simultaneously at
multiple scales, without regard to orientation.
|
AVHRR Time Series
AVHRR data,
C#
|
An exploratory analysis of vegetation data derived from
AVHRR satellite imagery that validated the observed increase
in northern hemisphere vegetation from 1981 to 2001, as reflected
in the growing season length.
