Description: TOPOS is an automated framework that optimizes spatial sampling directly onto 3D topographic surfaces instead of flat maps. It solves this by using geodesic distances derived from surface geometry and employs a Riemannian Nesterov Accelerated Gradient engine. This method corrects planimetric distortion, leading to a ~74% improvement in optimal distribution quality compared to standard 2D methods.
