In May, 2012, the U.S. Department of Education (ED) published approximately 300 2009–2010 school boundaries from the Public School Boundary Geodatabase (PSBG) on the School District Demographic Data System (SDDS) Map Viewer (http://nces.ed.gov/surveys/sdds). Using the previous process as a spring board, ED created a new data model for the boundaries covering the 2010–2011 through 2012–2013 school years using Esri ArcGIS 10.1 for Server and Desktop in addition to custom built Python tools. Improvements included data storage and sharing on the GeoCloud as well as replication and versioning for QA/QC purposes. Having implemented the new data model, we will reflect on work flow issues that arose and helpful tool automation. We will also discuss the future plans for the project.

Transcript

  • 1. CREATING A CLOUD BASED DATA MODEL FOR SCHOOL BOUNDARY COLLECTION 2013 ESRI Federal GIS Conference Presented by Tai Phan, Andrea Conver, & Amy Ramsdell NCES, Sanametrix & Blue Raster2/27/2013
  • 2. School Boundary GeodatabaseHistory Continuation of the SABINS project  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
  • 3. School Boundaries CollectionInitiative Collection of school attendance areas for all 13,000+ U.S. school districts Combination of data collection by Census and a “group-sourced” mapping effort The 2013-2014 school year will serve as a trial year Census Bureau is summarizing the data by school boundary
  • 4. Contact and Data TrackingApplication  Tracks all contact between the district and the Census collection team  Stores original data type (PDF, jpeg, Shapefile, etc.)  Records the date completed and user name for each processing step  Generates a variety of reports
  • 5. Contact and Data TrackingApplication
  • 6. School Boundary Technologies  Using ArcSDE 10.1sp1  CentralizedData Repository on Cloud  Data Replication  Using ArcGIS Server 10.1 on the Cloud  Data visualization  Data dissemination  Python (Arcpy)
  • 7. Data Model
  • 8. Data Processing & CustomToolbox  Collectboundaries  Dissolve boundaries into a 1 to 1 format  Associate boundaries with an unique ID  Perform QA/QC  Sync data to the Cloud
  • 9. School Boundary CollectionWorkflow
  • 10. Public School Boundary Collectionand Verification Tool
  • 11. Workflow Issues  Working with different teams in a variety of locations  No shared network  Data collection from a variety of sources  Data collection for multiple years  Determining what to collect  Refactoring QA/ QC based on requirements and deliverables
  • 12. Conclusions A simplified data model decreases file size and streamlines QA/QC  Custom tools have minimized human error, improved overall data quality, and reduced processing time  Network speeds can be a hindrance when working with SDE and data replication  Collecting data from the source  Using servers in the cloud increases accessibility
