Mapping religious sites will allow a better understanding of the religious landscape of the participating countries. Maps connect you to the matter at hand. They are functional tools to compile, display and share information, and support spatial thinking and planning. The geographically referenced information displayed provide context as they are visualized at a large scale. This mapping effort is made possible thanks to the engagement of relevant networks of government and religious organizations in-country and builds on existing information. UNAOC launched a global Call to Action for Safe Worship to support the UN Plan of Action to Safeguard Religious Sites. This paper explores the application of drone technology in accurately determining and fixing GPS coordinates of the Holy shrines of Imam Hussein and Imam Abbas in Karbala, Iraq. With millions of visitors annually, precise geospatial data is essential for security, navigation, urban planning, and crowd management. This study examines the use of advanced drone mapping techniques, including RTK (Real-Time Kinematic) and PPK (Post-Processed Kinematic) GPS, to enhance the accuracy of spatial data. Case studies of successful drone-based mapping projects worldwide are included to highlight best practices and potential applications in Karbala. By leveraging aerial photogrammetry and geospatial mapping, this approach enhances precision in shrine documentation, facilitates pilgrimage planning, and contributes to heritage preservation. The paper outlines the methodology used, results obtained, and potential implications for urban planning, security, and tourism. Keywords: Drones, GPS, Imam Huss
