What Earth Observation Can Do for Urban Areas
Earth observation (EO) offers urban planners, local authorities and city managers a powerful lens through which to understand, monitor and manage the complex dynamics of urban environments. Satellite data can map built-up areas and track urban expansion, monitor land surface temperatures and identify urban heat islands, assess green and blue infrastructure, detect subsidence and structural changes, and support flood and disaster risk management. By delivering consistent, up-to-date spatial information across entire cities and metropolitan regions, EO enables evidence-based urban planning and helps cities become more liveable, resilient and sustainable — in line with goals such as the UN Sustainable Development Goal 11 and the EU Mission for 100 Climate-Neutral and Smart Cities.
ESA's Role in Urban Applications
ESA supports urban communities through programmes and initiatives that develop space-based applications tailored to the needs of cities and local governments. Missions such as Copernicus Sentinel-1 and Sentinel-2 provide freely available, high-resolution data that underpin a wide range of urban monitoring services — from land cover mapping and green space assessment to infrastructure monitoring and emergency response. Through its Business Applications and Space Solutions programme and dedicated urban thematic activities, ESA collaborates with municipalities, urban research institutions and the private sector to co-develop and scale operational EO services. These efforts contribute to smarter, data-driven city governance and support Europe's broader ambitions for sustainable urban development.
How the Stakeholder Engagement Facility Supports Urban Authorities
The ESA Stakeholder Engagement Facility (SEF) works directly with urban authorities and city practitioners to lower the barriers to adopting Earth observation in urban planning and management workflows. SEF curates catalogues of EO-powered solutions relevant to urban applications and uses tools such as the Geospatial Explorer to demonstrate how satellite data can address the specific spatial and environmental challenges cities face. Through active community building, SEF helps urban stakeholders connect with the broader EO ecosystem and discover services suited to their needs.
Engagement with urban practitioners takes many forms. A cornerstone of SEF's outreach to cities is its close collaboration with the Covenant of Mayors Europe — the world's largest movement of local and regional authorities committed to climate and energy action. Together, SEF and the Covenant of Mayors have organised webinar series and joint outreach activities that bring Earth observation capabilities directly to city administrations across Europe, helping municipalities understand how satellite data can support their climate commitments, energy planning and urban resilience strategies. This partnership provides SEF with a direct and trusted channel to engage with a large and diverse community of local authorities at different stages of their EO journey.
At the individual level, SEF conducts deep dive sessions — focused, one-on-one interactions with urban authorities designed to understand their specific challenges, explore relevant EO solutions and provide tailored guidance on how to integrate satellite data into their decision-making processes. SEF also maintains an active presence at leading urban and smart city events, including the Smart City Expo World Congress in Barcelona and Urbis, engaging with city leaders and innovation communities to raise awareness of the transformative potential of space data for urban development.
