"Discovery of Patterns in Global Earth Science Data using Data Mining" | Abstract
Remote sensing data from global observing satellites, combined with data
from ecosystem models, offers an unprecedented opportunity for understanding
and predicting the behavior of the Earth's ecosystem. This data
consists of a sequence of global snapshots of the Earth, and includes
various atmospheric, land and ocean variables such as sea surface
temperature (SST), pressure, precipitation, vegetation index (NDVI),
and Net Primary Production (NPP). Due to the large amount of data
that is available, data mining techniques are needed to facilitate
the automatic extraction and analysis of interesting patterns from
the Earth Science data. However, mining patterns from Earth Science
data is a difficult task due to the spatio-temporal nature of the data.
This talk will discuss various challenges involved in analyzing the data,
and present some of our work on the design of efficient algorithms for
finding spatio-temporal patterns from such data and their applications
in discovering interesting relationships among ecological variables from
various parts of the Earth. A special focus will be on techniques
for land cover change detection (and their use in assessing the impact
on carbon cycle) and finding teleconnections between ocean and land variables.
Research funded by NASA, NOAA, and NSF
