Landsat GHSL: first available global dynamical assessment
Open public data + new processing methods
= new global information

Global population and built-up areas evolution in the last 40 years. The fine-scale built-up areas are estimated by the JRC GHSL using Landsat input imagery
Population estimates are extracted from the World Bank data

Global Human Settlement WG
• Established in October 2014 – supporting SB-04 “Global Urban Observation and Information”. http://www.earthobservations.org/ghs.php
• To develop a new generation of measurements and information products assessing new scientific evidences about global human settlement
• To support global policy processes with agreed, actionable and goal-driven metrics– the UN Third Conference on Housing and Sustainable Urban
Development (Habitat III, 2016) – the concurrent post-2015 processes on sustainable development, – the UN Framework Convention on Climate change – the Hyogo framework for Disaster Risk Reduction

GHS WG status (6 months life time)
• ~40 research teams registered alpha tester, >150 individual researchers
• Governmental, int. org., NGO, academic, private firms• Applications (so far): • damage and reconstruction assessment, impact assessment,
disaster early warning and alerting, losses estimates, exposure and risk mapping and post-disaster need assessment (PDNA)
• population spatial modeling, census planning, regional development and planning, transport planning, urban and global climate modeling, spatial epidemics analysis, ecological studies, environmental protection, agricultural fragmentation studies, and historical landscape protection
