Geospatial Metadata is information about a geospatial dataset that may not be contained in, or may not be readily apparent from, the Geospatial dataset itself. For example, you could view the coordinates of feature geometry in a vector data set, but may not be able to determine the spatial reference system from the coordinate values. You could view the name of a feature attribute, but that may not indicate what aspect of the real world that attribute represents. This is the type of inormation that can be encapsulated in geospatial metadata. | Geospatial Metadata is information about a geospatial dataset that may not be contained in, or may not be readily apparent from, the Geospatial dataset itself.

Geospatial Data Set
Simple Definition: A set or group of geospatial data with a common theme or association.
Additional Explanation or Clarification: Features belonging to a geospatial data set typically share a common feature schema or set of feature attributes. The term does not typically refer to a single feature. Geospatial datasets are often represented in a GIS by a thematic layer. Geospatial datasets are typically the main elements in a GIS Data Model.
Example: An ESRI Shapefile with a set of line features representing city streets could be called a Geospatial data set.

Geospatial Metadata
Metadata is often defined as "data about data". As an example, you might have metadata for a document might include the following information:
Identify the purpose of the document.
The date the document was written.
The date the document was last revised.
The author.
Geospatial Metadata is information about a geospatial dataset that may not be contained in, or may not be readily apparent from, the Geospatial dataset itself. For example, you could view the coordinates of feature geometry in a vector data set, but may not be able to determine the spatial reference system from the coordinate values. You could view the name of a feature attribute, but that may not indicate what aspect of the real world that attribute represents. This is the type of inormation that can be encapsulated in geospatial metadata.
