Transcript

  • 1. Building The Spatial Enterprise for Denver Public Schools Matthew Baker Department of Planning and Analysis
  • 2. ...Or: How I learned to stop worrying and love SQL Spatial.
  • 3. DPS Overview ● Fastest Growing District in USA ● 84,424 Students – Largest district in CO ● 120 Languages ● 172 Schools
  • 4. DPS Student Ethnicity
  • 5. DPS Student Performance
  • 6. Overview Planning & Analysis ● DPS Administration Building (900 Grant) – 1870 Lincoln (Summer 2014) ● Demographic Analysis and Projections – Student demand and performance ● Capacity and Resource Planning – Strategic Regional Analysis (SRA)
  • 7. Spatial Data and Client Applications
  • 8. Infinite Campus (IC) Students Teachers Principals Superintendent Administration Planning & Analysis All DPS database tables
  • 9. Spatial Data Primary ● School Points ● Boundaries ● Address Points ● Student Households (addresses) ● Planning and Forecast Regions ● October Count (Student count on Oct. 1)
  • 10. Address Point File ● Currently ~280,000 geocoded address points ● Central Database: Infinite Campus (IC) – Origin and source of truth for student data ● Weekly sync to IC addresses and GIS addresses – IC doesn't (yet) store spatial data!
  • 11. Spatial Data Other City & County of Denver ● Parcels ● Neighborhoods ● Street Centerlines ● Election Precincts ● Police Districts ● Historic Landmark Districts ● Zoning ● Land Use ● Council Districts Census ● Block Groups ● Blocks ● Tracts ● Birth data
  • 12. Clients DPS Enterprise ● IC - School Matrix ● School by Grade for each address point ● DPS Business Intelligence (BI) ● DPS Transportation Department ● Operational Data Store (ODS) ● Colorado Department of Education – CDE Pipeline
  • 13. DPS School Locator ● Enter Address ● Get: – Boundary Schools ● Elem ● Mid ● High – Transportation Info ● ArcGIS Server ● Google Maps API http://maps.dpsk12.org/
  • 14. Building the Spatial Enterprise
  • 15. Design Tasks Initial ● Identify and interview users and stakeholders ● Design GIS database – ArcGIS 9.3.1 to 10.1 ● Dev / QA database design ● Implement production ● Applications – Re-build ArcGIS Server – Re-build web applications (school locator, etc.)
  • 16. Workflow Challenges IC SQL Data Pull
  • 17. What's broken? ● Links to Data – Enterprise to GIS – SQL to Map ● ArcGIS – Access and create spatial data, no link to Enterprise ● SQL Server – Access tabular data – Enables enterprise-wide analysis – No access to spatial data
  • 18. Solution SQL Server Spatial
  • 19. Improvements ● SQL Server “workspace” – MS SQL Server 2012 – Analysts build and use spatial functions – Create and modify database views ● Use in Excel ● Use in ArcMap ● ETL Automation – To / From SDE – Analysis to DPS Enterprise, etc.
  • 20. Enabling SQL Spatial with FME ● FME Workbench – From SDE to SQL Spatial Native format – Create spatial index – Create Unique Object ID ● “Take What We Need” – Some fields for GIS – Some for SQL Analysis
  • 21. Creating Spatial Data with FME ● Assemble query in SQL ● Join Spatial data (shape field) – Using AddressID – Must also use OBJECTID for use in ArcMap ● Pull data from SQL to ArcSDE for use in GIS
  • 22. FME Workbench Example ● ~280,000 points x3 feature classes ● Reproject while loading ● Create SQL Spatial Index
  • 23. Other Benefits ETL with FME ● Promoting SDE Tables – Dev to QA – QA to Prod ● Simple tool for DBA to run ● Enter User/Pass ● ETL runs transparently
  • 24. SQL Spatial Example ● Need: – Grade 9 students – Projected School Assignment for 2015 – Within Specific Boundary ● Pulls from: – Projected Students – Address Master
  • 25. SELECT count( [Student_Number]) as StudentCount FROM [GISWork].[dpsdata].[ProjectedStudents] join [GISWork].dpsdata.[Address_Master] on (ProjectedStudents.addressID = Address_Master.AddressID) join GISWork.dpsdata.SchoolBoundaries_All on (Address_Master.shape.STIntersects(SchoolBoundaries_All.shape) = 1) where ProjectedGrade = '9' and SchoolBoundaries_All.HIGH_NUM = '464' group by ProjectedSchool order by StudentCount desc
  • 26. SQL Spatial Example ● Assign special needs transition-grade students to feeder or closest center program – Give top 3 closest schools by program – Distance to each school
  • 27. SELECT BT.[StudentID] ,BT.[LastName] ,BT.[FirstName] ,BT.[CurrentGrade] ,BT.[CurrentSchoolNum] ,BT.[CurrentSchoolName] ,BT.[ProjResSch] ,BT.[ProjectedEdLevel] ,BT.[CenterProgram] ,BT.[CenterProgramGroup] ,BT.[shape] ,ROW_NUMBER() OVER(PARTITION BY BT.[StudentID] ORDER BY ROUND((SC.Shape.STDistance(BT.Shape)/5280),2) ,CASE WHEN BT.[CenterProgramGroup] in ('AN','MI') and BT.[CurrentSchoolNum] = '447' THEN '466' WHEN BT.[CenterProgramGroup] in ('AUT', 'MI-Severe') and BT.[CurrentSchoolNum] = '419' THEN '469' ELSE SC.[CenterSchNum] END as [ProjFeederCenterSchNum] ,CASE WHEN BT.[CenterProgramGroup] in ('AN','MI') and BT.[CurrentSchoolNum] = '447' THEN 'DCIS/NCAS' WHEN BT.[CenterProgramGroup] in ('AUT', 'MI-Severe') and BT.[CurrentSchoolNum] = '419' THEN 'MLK' ELSE SC.[CenterSchName] END as [ProjFeederCenterSchName] --,CASE WHEN BT.[CenterProgramGroup] in ('AN','MI') and BT.[CurrentSchoolNum] = '447' THEN ,ROUND((SC.Shape.STDistance(BT.Shape)/5280),2) as [DistancetoFeeder] FROM (SELECT ST.[StudentID] ,ST.[LastName] ,ST.[FirstName] ,ST.[Grade] as [CurrentGrade] ,ST.[SchoolNum] as [CurrentSchoolNum] ,ST.[SchoolName] as [CurrentSchoolName] ,CASE WHEN ST.[grade] = '5th' THEN ST.[SCHOOL_6] WHEN ST.[Grade] = '8th' THEN ST.[SCHOOL_9] WHE [resschnum] END as [ProjResSch] --,ST.[ResSchNum] --,ST.[ResSchName] ,CASE WHEN ST.[grade] = '2nd' THEN 'ElemInt' WHEN ST.[grade] = 'Pre-K' THEN 'ElemPri' ELSE ST.[ --,ST.[DOB] --,ST.[Disability] ,ST.[CenterProgram]
  • 28. SQL Spatial Functions ● MSSQL Spatial – STIntersects – STContains – STDistance – STCentroid
  • 29. Tools Used ● SQL Server 2012 – Native Spatial Data / Geometry ● ArcGIS 10.1 – ArcGIS Server 10.2 ● FME Workbench ● PGModeler –
  • 30. Thank you! Matthew Baker Department of Planning and Analysis matthew_baker@dpsk12.org @MapBaker
