Claim 7:
8. A method for 3D reconstruction from satellite imagery, the method comprising:
providing (a) at least two at least partially overlapping 2D satellite images and (b) imaging device parameters for the at least two partially overlapping 2D satellite images to at least one trained Machine Learning Network (MLN),
wherein the MLN:
(a) has been trained on a training set comprising multi-view 3D geocoded ground truth data,
(b) the multi-view 3D geocoded ground truth data is at least one of (i) geocoded and extracted or (ii) rendered from a textured geocoded 3D surface model, and
(c) is configured to compute a depth map of the at least two partially overlapping 2D satellite images based on the corresponding imaging device parameters, wherein the computing of the depth map comprises associating data of the depth map to geocoded coordinate data.
