Abstract: This current invention relates to a system and method for 3D geospatial mapping that utilizes data from multiple sensors to deliver indoor positioning with precision at the floor level. The system combines GPS, barometric and an inertial magnetometer data through a multi-modal sensor fusion unit and utilizes machine learning for environmental calibration and atmospheric correction to improve precision in different conditions. A 15-state extended Kalman filter processor generates cohesive 3D location estimations, whereas a vertical positioning intelligence module identifies the user's floor level and changes. A rendering engine boosted by a GPU visualizes modified coordinates in engaging 3D settings and is helped by a smart cache management system for offline operation and a real-time sync controller for instant updates. The design helps in providing higher precision, offline dependability, making it suitable for emergency services, urban areas and intricate indoor navigation solutions. FIG.3
