Current Data
School Boundary Technologies
Using ArcSDE 10.1sp1
Using ArcGIS Server 10.1 EC2
Python (Arcpy)
Data Model
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
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
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
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
School Boundary Collection Workflow
Public School Boundary Collection and Verification Tool Demo
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
The Significance of School Attendance Boundaries
Benefits to the Districts
Benefits to the State
Benefits to social science
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
