Locating Urban Trees from Small Footprint Lidar
|
Image shows results of tree-finding algorithm displayed in Google Earth
with extruded building footprints, both based on Lidar data.
|
|
Mapping the Thermal Landscape with Small-Footprint Lidar and Landsat ETM+ Thermal Data. Boston-area imagery used to generate a map of correlations between land cover and urban heat.
|
|
|
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 (2001-2007).
|
|
|
Utility to interpolate pixels missing from Landsat ETM+ imagery acquired after May, 2003.
|
|
|
Comparison of climate model estimates of ice sheet extent versus NSIDC extent, under different climate change scenarios.
|
Left is polar view of NIC January 2003 ice chart; center is model output monthly
average for January, 2003; right is difference image.

|
A system for encoding and traversing the "rule space" of cellular automata models extracted from daily West Nile Virus risk rasters, presented at the Geocomputation 2007 conference (see CARSI lab for more information).
|
|
|
A quadtree based raster comparison metric for binary images that measures their similarity simultaneously at all scales, without regard to orientation, used for optimizing cellular automata rules.
|
|
|
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 length of the decidious growing season in the Eastern US.
|
|
|
A system to extract cellular automata transition rules from daily binary rasters of areas at risk of West Nile Virus infection.
