What is mosaic dataset?
Mosaic datasets are used to manage, display, serve, and share raster data. … A mosaic dataset consists of many parts: A catalog that provides the source of the pixels and footprints of the rasters. A feature class that defines the boundary. A set of mosaicking rules that are used to dynamically mosaic the rasters.

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 a mosaic image?

: the image formed by a compound eye (as of an insect) in which each visual facet receives independently a small portion of the image and the total visual impression is a composite of the various unit images.

What is raster data set?
A raster dataset is any valid raster format organized into one or more bands. Each band consists of an array of pixels (cells), and each pixel has a value. A raster dataset has at least one band. ArcGIS supports more than 70 different file formats for raster dataset, including TIFF, JPEG 2000, Esri Grid, and MrSid.
