  1. Innovative Data Collection Techniques for Public School Boundaries Management Information Systems Conference Presented by Tai Phan, Andrea Conver & Amy Ramsdell NCES, Sanametrix & Blue Raster

  2. School Boundary Geodatabase History • Continuation of the School Attendance Boundary Information System (SABINS) • Headed by Prof. Salvatore Saporito, The College of William & Mary • David Van Riper, Minnesota Population Center • www.sabinsdata.org • First release in the SDDS Map Viewer in May 2012 • 2009-2010 school boundaries for the top 350 districts • Census Bureau is summarizing the data by school boundary

  3. Current Data

  4. School Boundary Technologies • Using ArcSDE 10.1sp1 • Using ArcGIS Server 10.1 EC2 • Python (Arcpy)

  5. Data Model

  6. Data Processing Workflow • Collect boundaries • Dissolve boundaries into a 1 to 1 format • Associate boundaries with NCESSCH ID • Perform QA/QC • Sync data to the Cloud

  7. School Boundary QA/QC Procedures • Confirm that all regular schools have a boundary • Confirm that all attributes are correct and correspond to the NCESSCH school ID • Confirm that every geographical area is served by every grade

  8. Contact and Data Tracking Application • Tracks all contact between the district and the Census collection team • Stores original data type • Records the date completed and user name for each processing step • Generates a variety of reports

  9. Public School Boundary Collection and Verification • Collect boundaries for all 13,000+ U.S. school districts • Combination of data collection efforts by Census and a “group-sourced” mapping effort • The 2013-2014 school year will serve as a trial year

  10. School Boundary Collection Workflow

  11. Public School Boundary Collection and Verification Tool Demo

  12. Census Bureau Tabulations • Block rectification to create publicly available population counts and related information • These boundaries can be used for custom tabulations that meet the Census Bureau’s disclosure policies • Provide population counts at the school attendance boundary level • Product is not the same boundary lines as delineated by the districts

  13. The Significance of School Attendance Boundaries • Benefits to the Districts • Benefits to the State • Benefits to social science

  14. Moving Forward • Changes will be made to the workflow and tools based on process reviews and user feedback • The process will become easier and easier as more districts use the online collection and verification tool
