Abstract
In this paper, the internal operations of an Extended
Kalman Filter is investigated to see if any useful information
can be derived to detect land cover change in a MODIS
time series. The Extended Kalman Filter expands its internal
covariance if a significant change in reflectance value
is observed, followed by adapting the state parameters to
compensate for this change. The analysis shows a change detection
accuracy above 90% can be attained when evaluating
the elements within the internal covariance matrix to detect
new human settlements, with a corresponding false alarm rate
below 11%.
