The purpose of these derived datasets is more efficient and focused datasets for specific needs e.g., emergency services for disaster management without the need to duplicate capture and maintenance in multiple datasets. They are also viewed/portrayed as a feature class.
Within the Digital Topographic Data, the following datasets are derived datasets:

Feature Structure
In the vector data model, spatial features are represented as discrete geometric objects. These objects include points, lines, and polygons.
