What is a mosaic layer?

Mosaic datasets consist of three layers: boundary, footprint, and image. … The image layer controls the rendering of the mosaicked image similar to a raster layer. Display and rendering properties, such as stretch, band combination, resampling, and mosaic method, are modified on this layer.

What is mosaic in image processing?

Abstract: In image processing, mosaic images are images made by cementing together small tiles. … Creation of mosaic images from a sequence of partial views is a powerful means of obtaining a larger view of a scene than available within a single view, and it has been used in wide range of applications.

What is a mosaic dataset ArcGIS pro?

The mosaic dataset, created using ArcGIS Pro (or ArcMap), is the basis of image management in ArcGIS. A mosaic dataset is a form of catalog that references the source data, maintains relevant metadata, and defines processing to be applied to the rasters.

How does mosaic differs from a 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.
