What is a mosaic dataset ArcGIS?

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.

How many bands can a raster image have?

A raster dataset contains one or more layers called bands. For example, a color image has three bands (red, green, and blue) while a digital elevation model (DEM) has one band (holding elevation values), and a multispectral image may have many bands.
