Mosaicking is to join several overlapping images to form one uniform image. Think of it as similar to creating a jigsaw puzzle with your images, and then making the joints disappear. For the mosaic to look like a single image instead of a collage of images, it is important that the images fit together well.
The Mosaic Preparation module automatically performs all of the necessary preparatory procedures required to produce a high-quality image mosaic.
The module generates a series of files that describe how the image will be mosaicked. This includes creating cutlines for each image included in the mosaic, generating color-balancing and normalization coefficients to apply to each image, and applying exclusion masks to remove specific areas from the output mosaic.
After generating these components, you can either manually edit the results, or proceed directly to the Mosaic Generation module. Before running the Mosaic Generation module, you must prepare the mosaic, and you must do so regardless of whether you want to preview or edit your mosaic before generating it. Getting the results you want depends on the exclusion masks, the choice of color-balancing and cutline-generation algorithms, the scene order, and any manual adjustments you make.
The Mosaic Preparation module takes each scene specified and calculates radiometric-correction coefficients, cutlines, and a low-resolution mosaic-preparation overview.
