Generic GIS Skills

Q300. You have been hired as a consultant to estimate the effects of a new criminal offender registry law that prohibits individuals on the registry from living within 1000 meters of a school. You are asked to

  • a point layer with school locations
  • a street layer
  • a census blockgroup layer with information on number of rental units (or at least renter occupied units as of the last census)
