A geospatial platform for visualizing underground utilities in growing urban centers

Abstract

Urban development in rapidly expanding cities, especially in developing countries, is often hindered by limited access to accurate and current information on underground infrastructure. This paper introduces a web-based dashboard developed to map and visualize subsurface utilities in Kampala, Uganda. To support the development of this system, a field survey was conducted to collect baseline data on existing underground assets, validate geospatial records, and assess on-the-ground conditions. Designed to address critical data gaps, the dashboard integrates this field-verified information with open-source web technologies and multilingual support, offering an interactive and accessible platform for planners, engineers, and city officials. By enabling non-intrusive identification and exploration of underground assets, the dashboard supports safer construction practices, reduces the risk of accidental utility damage, and improves coordination among stakeholders. Ultimately, this solution contributes to more efficient urban planning and lays the foundation for Kampala's transition toward sustainable smart city development.
