  • Publication number: 20230419655
    Abstract: Systems and methods herein describe an image generation system that accesses a semantic map and satellite image, manipulates the semantic map image, trains a machine learning framework using a set of map and satellite image pairs, uses the trained machine learning framework to generate a manipulated satellite image based on the manipulated semantic map, generates a blended satellite image based on a combination of the manipulated satellite image data and the originally accessed satellite image data, and stores the blended satellite image.

  • Patent number: 11842471
    Abstract: Systems and methods herein describe a metadata verification system that is configured to access a digital satellite image, generate a first discrete Fourier transform (DFT) pattern based on an ortho-rectified digital satellite image, generate a second DFT pattern based on rational polynomial coefficient (RPC) data of the digital satellite image, compare the first DFT pattern to the second DFT pattern, generate a score based on the comparison, and generate a determination of whether the digital satellite image has been manipulated based on the score.
