feature class

A collection of geographic features with the same geometry type (such as point, line or polygon), the same attributes, and the same spatial reference.

1. Point - a geometric element defined by a pair of x,y coordinates
2. Poly Line - a shape defined by a series of connected line segments
3. Polygon - a closed shape defined by a connected sequence of x,y coordinate pairs, where the first and last coordinate pair are the same and all other pairs are unique

1. A classification describing the format of geographic features and supporting data in a coverage. Coverage feature classes for representing geographic features include point, arc, node, route-system, route, section, polygon and region. One or more coverage features are used to model geographic features; for example, arcs and nodes can be used to model linear features such as street centerlines. The tic, annotation, link, and boundary feature classes provide supporting data for coverage data management and viewing.
2. The conceptual representation of a geographic feature. When referring to geographic features, feature classes include point, line, area, and surface.

The type of feature represented in a coverage. Coverage feature classes include arcs, nodes, label points, polygons, tics, annotation, links, boundaries, routes, and sections.
