Geo-information on human settlements
• Required for modeling, analysis, policy-making(i.e. producing indicators and monitoring targets):
• Sendai Framework for DRR 2015-2030 (adopted Mar. 2015)• 2030 Agenda for Sustainable Development (SDGs, Sept. 2015)• COP 21 Paris Agreement on Climate Change (Nov. 2016)• Habitat3 – New Urban Agenda (Dec. 2016)
• Exposure (to hazards, pollutants,…)• Access (to resources, services,…)• Impacts (from natural disasters, environmental change,…)

Geo-information on human settlements
• Producing indicators and monitoring targets, global scope:
• Up-to-date
• Detailed
• Consistent (comparable)
• Sustainable (repeatable, cost-effective)
• Transparent (clear methods)
• Open & free

What we detect: “built-up area” = all spatial units (30x30m) where a building or part of a building can be recognized
Low-level abstraction improve semantic interoperability

GEO Human Planet Initiative
• New initiative in the GEO 2017-2019 work programme supporting the GEO Strategic Plan 2016-2025.
• Aims to support novel evidence-based assessment of the human presence on the planet Earth.
• Leverages on advances of Earth Observation technologies and geo-spatial data analytics for improving the global awareness on the spatial patterns and processes of the today’s urbanizing world.

Conclusions
• Free and open data and methods• Leave no one behind• Create trust (reproducibility)
• Combination of EO data with non-EO data
• Networking outside the EO community is important
