1. Building The Spatial Enterprise
for Denver Public Schools

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

7. 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)

8. Spatial Data and Client Applications

9. Infinite Campus (IC)
Students
Teachers
Principals
Superintendent
Administration
Planning
&
Analysis
All DPS database tables

10. Spatial Data Primary
● School Points
● Boundaries
● Address Points
● Student Households (addresses)
● Planning and Forecast Regions
● October Count (Student count on Oct. 1)

11. 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!

12. 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

13. 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

14. DPS School Locator
● Enter Address
● Get:
– Boundary Schools
● Elem
● Mid
● High
– Transportation Info
● ArcGIS Server
● Google Maps API
http://maps.dpsk12.org/

15. Building the Spatial Enterprise

16. 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.)

17. Workflow Challenges
IC
SQL Data Pull

18. 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

19. Solution SQL Server Spatial

20. 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.

21. 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

22. 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

23. FME Workbench Example
● ~280,000 points x3 feature classes
● Reproject while loading
● Create SQL Spatial Index

24. 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

26. SQL Spatial Example
● Need:
– Grade 9 students
– Projected School Assignment for 2015
– Within Specific Boundary
● Pulls from:
– Projected Students
– Address Master

27. 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

28. 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

29. 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]
