Planning

The planning reflects clear near-term goals and general expectation of long-term goals. near-term means in weeks; long-term means in months. For deliverables, code must be checked in SVN; documents should be uploaded to wiki and linked on wiki page

  1. Jan 10: finish documenting anomalies in near table generation at block level and initial interpretation on the anomalies
    • Deliverable: a tech report demonstrating anomalies and initial interpretation
    • Deliverable: a set of shape files, each including the polygons involved (including neighbors) in the anomaly
  2. Jan 13: comparison of polygon adjacency & bordering matrix generation methods: ArcGIS near table, ArcGIS spatial relationship, GeoDa spatial weights calculation
    • Deliverable: a tech report on accuracy/correctness, scalability, and performance for the three aforementioned methods
  3. Jan 17: finish initialization strategy coding with hole checking
    • Deliverable: hole checking algorithm and associated data structure
    • Deliverable: a revised initialization algorithm
    • Deliverable: unit test cases which at least show two scenarios, one with holes, the other without
  4. Jan 24: finish tract-level redistricting code and technical documentation, ready for code review and testing; start writing for GIScience conference paper
    • Deliverable: code in SVN
    • Deliverable: technical document on how to run the code, with sample datasets
  5. Data pre-processing
    • Handle exception 1: a unit is contained in another unit. This can be done by removing the contained unit before running the algorithm and putting it back in final solution
    • Handle exception 2: a unit has two or more polygons. What to do?
  6. March 21: finish redistricting at tract level and produce a single SVN code version with README file; document runtime environment and library dependency, as well as compiling (if needed), running, and testing instructions
  7. March 21: review exception handling to see if, for exception 2, area difference among unit polygons is large or not
  8. March 21: discussion agenda: 1) extended abstract timeline; 2) journal paper development
  9. May 04: Extended abstract for GIScience 2012 due

Q&A

  • At tract level, should we do multi-scale optimization, i.e., using multi-obj pareto front at county-level to guide tract-level optimization? If yes, explain why and propose a time line; if not, explain why, too
