Claim One:
1. A method for automatic cutline generation for merging at least two geospatial images to produce a composite image, the method comprising: identifying at least a first geospatial image and a second geospatial image, wherein at least a portion of the first geospatial image and the second geospatial image overlap in an overlapping region; obtaining a low resolution first geospatial image corresponding to the first geospatial image and a low resolution second geospatial image corresponding to the second geospatial image; determining a low resolution cutline relative to adjacent pixels of the low resolution first geospatial image and the low resolution second geospatial image in the overlapping region, wherein the cutline is located between adjacent pixels from respective ones of the low resolution first geospatial image and the low resolution second geospatial image based on a radiometric difference therebetween; expanding the low resolution cutline to define a cutline area in the overlapping region of the low resolution first and second images, wherein the cutline area is defined by cutline area boundaries; applying the cutline area boundaries to the overlapping region of the first and second geospatial images to define a corresponding cutline area in the overlapping region of the first and second geospatial image; and establishing a high resolution cutline relative to adjacent pixels of the first geospatial image and the second geospatial image in the cutline area, wherein the high resolution cutline is located between adjacent pixels from respective ones of the first geospatial image and the second geospatial image based on a radiometric difference therebetween in the cutline area.
