Why do we mosaic images?
Mosaics are used to create a continuous image surface across large areas.

Or you can manage an entire historical map series for a nation for every year and every map scale.
What is a mosaic map?
A mosaic map is a map made up of different images which are displayed depending on availability and zoom level. The mosaic map can have one or more overlapping layers, so, if you zoom in or zoom out, one or another layer will be shown. For example, if you zoom out, low quality layers will be displayed.

What is a raster layer?
Raster layers are the most obvious kind. When you draw, paint, or paste an image as a new layer, you are working with raster layers. These layers are pixel based. The background layer is always a raster layer. Control layers are not visible themselves; they just control the appearance of other layers.
Can you merge raster data?
The Merge Rasters function groups or merges a collection of rasters. Use this function when you have multiple rasters that you want treated as a single item, such as calculating the same statistics for all images, or when color balancing so you don’t need to color balance each image separately.
