Vector features:
Points:
Points geometry: A point feature is described by its X, Y and optionally Z coordinate. Point attributes: id, name description Example: 2, Tree, outside our classroom
Lines:
Polyline geometry: A polyline is a sequence of joined vertices. Each vertex has an X, Y (and optionally Z) coordinate. Example: 2, Footpath 2, Ferom the school gate to the hall.
Polygons:
A Polygon like a polyline, it is a sequence of vertices. However in a polygon, the first and last vertices are always at the same position.
