In urban planning, geospatial technologies—which include Remote Sensing (RS), Geographic Information Systems (GIS), Global Positioning Systems (GPS), and spatial data analytics—have emerged as transformative tools. These technologies help in precise spatial data collection, visualization, and analysis, laying the groundwork for well-informed urban planning and management decisions. As cities face rapid population growth and environmental challenges, geospatial technologies play a critical role in addressing these complexities by integrating spatial and temporal data to foster sustainable urban development. Remote sensing, through satellite and aerial images, offers real-time monitoring of urban growth and environmental changes. GIS facilitates mapping and management of urban resources, enabling urban planners to visualize land-use and zoning patterns. GPS, coupled with location-based services, enhances urban mobility planning by optimizing public transportation systems. Advances in spatial data analytics further enable predictive modelling and helping cities anticipate future growth patterns. Moreover, geospatial technologies contribute to smart city initiatives by integrating Internet of Things (IoT) data, enhancing urban resilience, and promoting involvement of urban residents. Further, these technologies align with the United Nations’ Sustainable Development Goals (SDGs). Despite their potential, challenges including shortages in technical competence, high implementation costs, and data privacy concerns are prevalent. To sum up, geospatial technologies are essential to contemporary urban development because they help cities move towards resilience, efficiency, and sustainability. Their incorporation into urban planning procedures promises transformative outcomes, creating smarter, more liveable cities for coming generations.
