Using Overview Manager

In the Overview Manager window you can can create, manage, and remove raster overviews for a specific image file or layer. The window also displays relevant information about the current file, layer, and any existing overviews.

A raster overview is a reduced-resolution version of the raster itself. Using overviews can significantly increase your efficiency—espcially when working with large data sets—because overviews open and display much faster than full-resolution rasters.

Note: Building raster overviews can use a large amount of disk space. Make sure you have sufficient disk-free space before creating overviews.
