Discussion

Geospatial professionals by nature, rely to a large extent on visual information to gain understanding of resources. Browse graphics provide in the metadata a way to communicate with users visually.

Best Practice Recommendations

Therefore - in order to provide a quick way for users to discover and identify the resource they need, provide a graphic overview in the metadata. At a minimum this should include a name and link to the image.
