DESCRIPTION
The Planning and Analysis department at Denver Public Schools is the center of support for the 2nd largest school district in the State of Colorado, and spatial data is a crucial enabler of most of the analysis that is done in our department. Recently, however, we begun to re-think how our data could be used, and started a complete overhaul of our planning database. This session will examine the use of maps and analysis at DPS, the process of merging our Geographic Information System with a Spatial Information Technology workflow, and how this new database serves the needs of analysts throughout the district. Topics covered will include how we use spatial data, SQL analysis, and GIS processes to support the workflows of our analysts, the tools used to create the new database design, load data, and test it across the enterprise, and where our spatial and SQL analysis will go in the years to come.

DPS Overview
● Fastest Growing District in CO● 84,424 Students
– About to become largest district in CO
● 120 Languages● 172 Schools
DPS Student Ethnicity
DPS Student Performance
Overview Planning & Analysis
● DPS Administration Building● Demographic Analysis and Projections
– Student Demand and Performance
● Capacity and Resource Planning– Strategic Regional Analysis (SRA)
Special Challenges
● NCLB– DPS one of first districts in US to close school
● School of Choice Process– Choice Zones vs. School Boundaries– ½ of students choice “out”
● Aggressive Implementation of Charter and Innovation Schools
● School Phase In / Phase Out
History DPS GIS
● Originally Planning and Transportation had separate GIS
● GIS Specialist created to bridge gap● Transportation later silo'd to non-GIS routing● GIS managed by Planning & Analysis and
served to enterprise systems

Spatial Data Primary
● School Points● Boundaries● Address Points● Student Households (addresses)● Planning and Forecast Regions● Transportation● October Count
Address Point File
● Currently ~280,000 geocoded address points– Student Household locations
● Infinite Campus (IC): Central Database– Origin and source of truth for student data
● Weekly sync to IC addresses and GIS addresses– IC doesn't (yet) store spatial data!
● Upcoming Internship with CO OIT– Emily Griffith Technical College
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
Clients DPS Enterprise
● School Matrix– Address Point with Boundary, Grade Info
● Business Intelligence● IC● Operational Data Store (ODS)● Colorado Department of Education
– CDE Pipeline
Clients DPS School Locator
● Enter Address● Get:
– Boundary Schools● Elem● Mid● High
– Transportation Info
● ArcGIS Server● Google Maps API
http://maps.dpsk12.org/
● ArcGIS Online-based Application● Enabled non-GIS users in Facilities
to digitize and prioritize irrigation areas at all DPS facilities
● Took 2 days to complete!
Building the Spatial Enterprise
Design Tasks Initial
● Identify and Interview users and stakeholders● Design GIS database● DEV / QA database design● Implement production● Applications
– Re-build ArcGIS Server
– Re-build web applications
Workflow Example
IC
SQL Data Pull
What's Broken?
● Broken Data links– SQL to Excel
– SQL to Map
● ArcGIS creates spatial data● SQL Server creates tabular data● How to blend?
Improvements● SQL Server “Workspace”
– Planners Build and Use Spatial Functions– Storing Query Views
● Use in Excel● Use in ArcMap (spatial views)
● ETL Automation– From DPS Enterprise
● To SQL Workspace
– To / From SDE● To DPS Enterprise
SQL Spatial
GIS
Planning & Analysis
Workflow Target
ODS DPS Enterprise
Tools Used
● SQL Server 2012– Spatial data: geometry
● ArcGIS 10.1● FME Workbench● PGModeler
– PostgreSQL database modeler
