Vertex
A single coordinate point in a ring or line; polygons are made of many vertices.
Category: Geometry
Definition (expanded)
Vertices are the individual points defining geometry shape. Too many vertices can slow down browser tools and GIS operations. Simplification reduces vertex count while approximating shape.
