Granules (the individual files that make up a collection or data= set) can be associated with preview images. They can be either PDFs of comp= osite data or browse images associated with the actual data. To add thumbna= ils to your collection's granules, follow the steps below.
Providers create and update granule metadata with a variety of different= tools. As such, this article will not detail how to create a= nd update metadata, but focus on what metadata should be prov= ided.

Note, CMR indexes granules on ingest. When granules are ingested, CMR wi= ll look for the presence of a BROWSE OnlineResource. If one is found, the "= browse_flag" will be toggled from false to true. Earthdata Search looks for= "browse_flag: true" and will then pick up the image linked in the Online R= esource URL.
