Geospatial innovation is transforming urban landscapes by integrating advanced technologies such as Geographic Information Systems (GIS), remote sensing, artificial intelligence (AI), and the Internet of Things (IoT) to enhance smart city development, eco-synergy, and urban resurgence. This chapter explores how geospatial technologies enable data-driven urban planning, optimising infrastructure, resource management, and environmental sustainability. The role of geospatial intelligence in predicting urban growth patterns, mitigating risks, and improving real-time decision-making is highlighted, emphasising its significance in fostering resilient and adaptive cities. The chapter also examines eco-synergy, where geospatial technologies contribute to sustainable urbanisation by promoting green infrastructure, mitigating climate change impacts, and enhancing biodiversity conservation. Additionally, geospatial tools play a crucial role in urban resurgence by revitalising declining urban areas through digital twin technology, 3D city modelling, and spatial analytics. The evolution of geospatial technologies is traced from traditional cartography to modern AI-driven urban intelligence, showcasing their increasing relevance in contemporary city planning. By addressing challenges such as data interoperability, privacy, and the need for standardised frameworks, this chapter provides information on the future of geospatial innovation and its potential to drive smarter, greener, and more resilient cities.
