Mosaic is a technique joining two or more satellite imagery in a single appearance that is consistent and continuous, aligned in terms of color and contrast
sustainable in terms of the object surface is perfectly connected. mosaicing process and remove the cloud can only be done on images that have been corrected geometrically well. Surface objects such as roads, rivers and other appearance due to human activities should not be interrupted in the joint image. when found object connection is lost on the image, then the process orthorectification must be repeated before going on the mosaic.
Meanwhile, remove the cloud is a process that aims to change inherent in the cloud Quickbird imagery with other data, can use Quickbird data different from the date of recording, data IKONOS high-resolution data and other, such WorldView1 and WorldView2. Not all Quickbird scene can be eliminated
clouds a hundred percent, in certain areas have a massive cloud coverage and intensive
This is an illustration of the mosaic between two images:
