Layers (OCGs)

PDF OCG (Optional Content Groups) dictionary represents a collection of graphic objects that can be made visible or invisible. Any graphic content of the PDF can be made optional, including page contents, XObjects, and annotations.

You can view the layers separation sample here.

With the introduction of PDF version 1.5 came the concept of Layers. Layers, or as they are more formally known as Optional Content Groups (OCGs), refers to sections of content in a PDF document that can be selectively viewed or hidden by document authors or consumers. This capability is useful in CAD drawings, layered artwork, maps, multi-language documents etc.
