Feature classes

A feature class is a collection of geographic features with the same geometry type, attributes, and spatial reference. Feature classes can also store annotation, which you'll learn about later in this course.

For example, all the telephone poles in London could be represented as a feature class in a geodatabase. Streets would be another feature class. London districts would be a third feature class.

Feature classes may exist independently in a geodatabase as standalone feature classes or they can be grouped into feature datasets.

 

Three feature classes in the SouthAmerica geodatabase

 

The SouthAmerica geodatabase contains three standalone feature classes: a point feature class of cities, a polygon feature class of countries, and an annotation feature class of country names.
