Techniques for automatically removing slivers from orthomosaics. First, slivers may be identified, which may be based upon user-configurable characteristics such as width and length. Second, slivers may be replaced with portions of another image, such as an older image. Third, boundary slivers may optionally be removed. Fourth, remaining boundary or interior slivers can be inflated by expanding the sliver until it is no longer a sliver, which may include replacing a portion of an adjacent image portion with older imagery.
