Vector layer geometry types: Point, line and polygon

Each vector layer in GIS has one type of geometry. It can be:

  1. Point – a location on the ground described by a pair of X and Y coordinates. E.g. the location of a tree, or a hydrant lamp post.
  2. Line – a segment consisting of one or more segments or more geometrically speaking: a broken line. We use a line to draw a water pipe, cable, or road.
  3. Polygon, surface, or most formally: a closed broken line. A type of geometry that allows you to mark a lake, a district, or a municipal boundary.

What does the geometry type affect?

  1. analytical tools
  2. symbolisation tools
  3. editing tools
