Disaster Influence on Property Prices (1) • Objective: Provide computational analytics for estimating how an event influences property values • Dataset: Miami-Dade county records (~ 20M) • Community Boundaries: U.S. Census Blocks and Tracts (polygons) • Property transaction geo-database: Join of property public records (Deeds, Tax Roll) HPDRC.FIU.edu TerraFly.com
Disaster Influence on Property Prices (2) Map • Method • Virtual Community (VC): a set of homes with similar characteristics within a geographical area • Consider unit price per VC, e.g. median of $/sq-foot • Compute VC’s unit price rate change to compare communities • HadoopMapReduce: Temporal, in parallel, self-join of the dataset to compute property value rate change Reduce … … Reduce Map (Computes community values and change rate) (Partitions records by: Community, Type, Date) Output: Community value change rate Input: dataset, tstart, tend
