  6. TerraFly Maps HPDRC.FIU.edu TerraFly.com

  7. Your System Your Data TerraFly IntegrationSolution TerraFly system HPDRC.FIU.edu TerraFly.com

  8. Historical Property Values Time Series Animation Player Layer Control Query Date Range Census Block Groups are Selectable HPDRC.FIU.edu TerraFly.com

  9. MapReduce in TerraFly MapReduce use cases • Spatial data indexing [SSDBM’09] • Geospatial query support [SSDBM’10] • Parallel spatial data processing [GrC’10] • Parallel set-similarity spatial joins • Real Estate data analytics HPDRC.FIU.edu TerraFly.com

  10. 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

  11. 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

  12. Disaster Influence on Property Prices (3) Raise Hurricane Andrew, August 1992, Q2’92 vs. Q4’92 Drop No change HPDRC.FIU.edu TerraFly.com
