map feature

A map feature is an object that represents a cartographic data as it was read from its source file. It can be a segment of road, an aerial image, the summit of a hill, or a digital terrain model. A map feature holds three main information fields: its geometry, the projection in which its geometry is expressed, and its attributes.
