Urban areas are expanding rapidly, bringing a multitude of challenges such as uncontrolled urban sprawl, increased environmental pressure, and rising inequalities. Monitoring these changes and ensuring that urban development aligns with the Sustainable Development Goals (SDGs) requires accurate and timely data. This data is essential for tracking progress, making informed policy decisions, and supporting sustainable city planning. However, collecting this information from the ground is resource-intensive, and traditional methods often lack the resolution and timeliness required for effective decision-making.
Earth Observation (EO) technologies, particularly those provided by satellite data, offer a powerful solution for monitoring urban development. EO enables stakeholders to track key indicators related to urban growth, environmental impact, and sustainability providing continuous data updates. Tools developed by ESA-funded projects such as Urban TEP and IdeaAtlas specifically address the needs of cities, urban planners by offering dedicated platforms to process EO data that support the computing of related information such as land use change, air quality, heat islands, map and characterisation the spatial extent of slums. Through advanced analytics and AI-driven models, these platforms transform satellite data into actionable insights, supporting cities in their reporting obligations under SDG 11—"Sustainable Cities and Communities."
