Metadata, or "data about data", helps to ensure the long-term utility of a data set by capturing the basic characteristics of a data or information resource. A metadata record includes a general description, what time period the data represents, sources used to develop the data, and an overview of the data capture/automation procedures. As an official GIS Clearinghouse Node , NH GRANIT is required to provide FGDC-compliant metadata for all layers distributed through the online metadata database.
