What is the purpose of a browse graphic?

A browse graphic is an image of the data set. The image allows prospective users to move beyond textual descriptions and see what the data set looks like. The image might show a simple display of the data set, the results of an application that used the data set, different aspects of the quality of the data set, or other information. Examples:

A reduced-scale plot of the hydrography overlay from the SDTS-encoded Digital Line Graph data set for Wilmington South, Delaware-New Jersey.

Portion of an orthophotoquad near Palm Springs, California.
