Automatic generation of a mosaic comprising a plurality of geospatial images. An embodiment of the automatic mosaic generation may include automated source image selection that includes comparison of source images to base layer image to determine radiometric similar source images. Additionally, an embodiment of an automatic cutline generator may be provided to automatically determine a cutline when merging two images such that radiometric differences between the images along the cutline are reduced. In this regard, less perceivable outlines may be provided. Further still, an embodiment of a radiometric normalization module may be provided that may determine radiometric adjustments to source images to match certain properties of the base layer image. In some embodiments, when processing source images, the source images may be downsampled during a portion of the processing to reduce computational overhead. Additionally, some highly parallel computations may be performed by a GPU to further enhance performance.

A method for radiometric normalization of a target image relative to a base image, comprising:
The method of claim 27, wherein the saturated pixel value removed from the calculating by way of the masking is identified as a pixel corresponding to water or a cloud.
The method of claim 31, wherein the geospatial base layer image comprises a global color balanced mosaic image.
A system for radiometric normalization, comprising:
