This document proposes an integrated management system for sea ports using geographic information systems (GIS). The key features of the proposed system include asset mapping, monitoring, and management; business intelligence maps and data analytics; security management; and integration with existing management information systems. The system aims to provide situational awareness of port assets, efficient utilization of assets, and effective planning and response to emergencies. Benefits include increased asset tracking and utilization, improved decision-making based on operational visualization, and maximized use of port infrastructure and assets.
