Introduction:

Metadata, often referred to as "data about data", is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource. It represents the who, what, when, where, why and how of the resource.

Metadata found on this website is organized by category and theme. Each metadata record also includes a link to the data being described.

While the Department of Natural Resources hosts the data found on this website, it comes from a variety of sources, including the Department of Fish & Game and Department of Transportation & Public Facilities.
