6. Calculate distance around Phoenix College and
reclassify distance into nine categories with an

9. Reclassify tract as a raster wih nine categories.
10. Download census tract data for Maricopa County, Arizona, from
http://www.factfinder.census.gov/ (median house value)

Fisrt weighted overlay
* Reclassed hospital: 25%
