China 100m Urban change
DATASET: Alpha version of temporally-comparable 1990, 2000, and 2010 estimates of numbers of people per pixel ('ppp') and people per hectare ('pph') - produced using covariates that are either time-invariant or temporally explicit.
REGION: Asia
SPATIAL RESOLUTION: 0.000833333 decimal degrees (approx 100m at the equator)
PROJECTION: Geographic, WGS84
UNITS: Estimated persons per grid square
MAPPING APPROACH: : Random Forest
