Spatial AI & Autonomous Navigation Coordinate Systems Guide

Autonomous vehicles, robotics, and Spatial AI systems seamlessly bridge global satellite positioning (WGS84 / ECEF) with local sensor perception (LiDAR point clouds, Visual Odometry, HD Vector Maps). Converting between Earth-Centered Earth-Fixed (ECEF) coordinates and Local Tangent Plane (ENU / NED) frames is critical for millimetric obstacle avoidance and trajectory planning.
