THE TRENTON BOARD OF EDUCATION MEETS GIS

  1. 1. The Trenton Board of Education meets GIS Mapping School Attendance Catchment Areas Trish Long Senior Planner City of Trenton Department of Housing and Economic Development June 2010
  2. 2. The Setting <ul><li># of K-8 schools in Trenton: 20 </li></ul><ul><li># of schools reconstructed since 2000: 4 </li></ul><ul><li># of schools to be closed in 2010: 3 </li></ul><ul><li>Board of Education Street Directory </li></ul><ul><ul><li>30 page listing, including </li></ul></ul><ul><ul><ul><li>street name , low address, high address, school name, “Odd Even,” grade </li></ul></ul></ul><ul><ul><li>last revised in 1997 </li></ul></ul><ul><ul><li>no existing electronic file </li></ul></ul><ul><ul><li>Over the years, changes were either handwritten on the front cover of the street directory or remained in a staff person’s head. </li></ul></ul>Introduction Project Goals Our Approach The Future
  3. 3. <ul><li>GOAL 1: To create a new Street Directory using up-to-date centerline data. This Directory could potentially be used by: </li></ul><ul><ul><li>Central Registration and the Transportation/Busing Department </li></ul></ul><ul><li>GOAL 2: To use the updated street directory to create a map of school attendance catchment areas </li></ul>Introduction Project Goals Our Approach The Future
  4. 4. <ul><li>STEP 1: Enter street directory data into a spreadsheet </li></ul><ul><li>STEP 2: Reconcile the Street Directory data with the City’s new Master Street File to: </li></ul><ul><ul><li>Identify streets missing from the directory </li></ul></ul><ul><ul><li>Determine if there are homes on the new streets (tax assessor was able to answer these questions) </li></ul></ul><ul><ul><ul><li>No residences? Keep street in the dataset, but do not assign a school to that street, at this time. </li></ul></ul></ul><ul><ul><li>Improve the quality of information associated with each street segment </li></ul></ul><ul><ul><ul><li>e.g., verify street names , break out “lo-high” into FromLeft, ToLeft, FromRight, ToRight, correct school assignments, incorporate notes </li></ul></ul></ul>Introduction Project Goals Our Approach The Future
  5. 5. STEP 3: Once the street data was updated, we began assigning the schools to each street. Here is a sample what the Directory now looks like: Grades Kindergarten to 8th From/To Left From/To Right
  6. 6. <ul><li>STEP 4: </li></ul><ul><li>Join the updated Street Directory with the new Master Street File (centerline data) in ArcGIS. </li></ul><ul><li>STEP 5: </li></ul><ul><li>Map the data to illustrate the problems/omissions. The map allowed us to see and make the necessary changes. </li></ul>Introduction Project Goals Our Approach The Future
  7. 7. <ul><li>Initial ideas for the catchment area maps: </li></ul><ul><li>The areas would be represented by polygons. </li></ul><ul><li>To identify gaps, we could generate one layer for each grade level. </li></ul><ul><li>We could also generate a layer for each school. </li></ul><ul><li>Lots of possibilities for overlaying layers. </li></ul><ul><li>Maps produced on May 14, 2010: </li></ul><ul><li>1) All K – 5 grades </li></ul><ul><li>2) All 6 – 8 grades </li></ul><ul><li>3) All schools with grades K - 5 </li></ul><ul><li>4) All schools with grades K - 8 </li></ul>Introduction Project Goals Our Approach The Future
  8. 8. <ul><li>Sample School Attendance Catchment Area maps… </li></ul>Introduction Project Goals Our Approach The Future
  9. 9. <ul><li>Sample School Attendance Catchment Area maps… </li></ul>Introduction Project Goals Our Approach The Future
  10. 10. <ul><li>Next Steps: </li></ul><ul><li>Final assignment of schools to street segments by Board of Ed staff </li></ul><ul><li>Republication of street directory and maps </li></ul><ul><li>Ultimate solution: Upload school catchment data layers to Trenton’s Internet DataViewer </li></ul>Introduction Project Goals Our Approach The Future
