Why do we mosaic images?
Mosaics are used to create a continuous image surface across large areas. For example, among other scenarios, you can use mosaics to handle coverage of very high-resolution image files for an entire continent. Or you can manage an entire historical map series for a nation for every year and every map scale.
What is mosaic tool?
Mosaic is useful when two or more adjacent raster datasets need to be merged into one entity. … The overlapping areas of the mosaic can be handled in several ways; for example, you can set the tool to keep only the first raster dataset’s data, or you can blend the overlapping cell values.

What is mosaic effect?
Mosaic effect means a situation in which information in an individual dataset, in isolation, may not pose a risk of identifying an individual, but when combined with other available information could pose such a risk.
What is mosaics and its types?
