Spatial <strong>Data</strong> Mining: Motivation<br />
� In many applications, the interesting<br />
patterns are location dependent<br />
� Classical example is the 1854 cholera<br />
outbreak in London<br />
� Deaths were spatially clustered in a<br />
polluted water pump in Soho, as shown<br />
by the map by John Snow<br />
� The connection of cholera and polluted<br />
water was not known at the time<br />
� Nowadays, data <strong>mining</strong> is used to<br />
monitor disease outbreaks<br />
