Feature Types
The definition of features that share membership of a common theme is a feature type, though there are a number of terms for this characteristic, including category, feature class, group, layer, level, object, and theme.
Layer served as the traditional term of choice, but use of this word has declined as data has become more object-oriented and less concerned with cartographic layering.
Data modelers can use feature types to create a hierarchical structure. For example, a dataset may consist of types called highways, streets and lanes. The system may group these particular types together under a category called "Roads".
