  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] • Support to geospatial queries [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: How an event influenced property values? • Property transaction geo-database • Join of property public records (Deeds, Tax Roll) • Method • Virtual Community (VC) is set of homes with similar characteristics within a geographical area • We considerunit price per VC, e.g. median of $/sq-foot • We compute VC’s change rate of unit prices to compare communities HPDRC.FIU.edu TerraFly.com

  11. Disaster Influence on Property Prices (2) • Dataset: Miami-Dade county records (~ 20M) • Community Boundaries: U.S. Census Blocks and Tracts (polygons) • Hadoop MapReduce to self-join the dataset in parallel on community values at different times and compute rates Map Reduce … … Reduce Map (Computes community values and change rate) (Partitions records by: Community, Type, Date) Output: Community value change rate Input: dataset, tstart, tend HPDRC.FIU.edu TerraFly.com
