Locally adaptive spatially explicit population projection system

A locally adaptive spatial system renders spatially explicit population projections. The system identifies selected land areas that are excluded from future development. It identifies potential growth areas that identify land areas that are projected to gain populations by modeling land variables. The system classifies the population projections as infill or sprawl based on the current local urbanization index and identifies potential loss surfaces that identify land areas that are projected to lose populations. The system spatially allocates population changes at a county level based on the infill, sprawl, and population loss designations.
