Gridded Population of the World v4 (NASA SEDAC)

Gridded Population of the World v4 (NASA SEDAC)

MH Subset Needed

Census-based gridded population counts and density at ~1km (30 arc-second) resolution for 5-year intervals from 2000 to 2020 with projections to 2025. Essential for disaster risk assessment, urban planning, and service delivery planning when overlaid with satellite data for Maharashtra.

Build a population exposure analysis tool for Maharashtra hazards using NASA SEDAC gridded population.
Maharashtra subset not yet extracted. This is a global dataset that contains data covering Maharashtra. A regional subset can be extracted by filtering on geographic coordinates or administrative boundaries.
