Write the definition of vector data in G.I.S.

Vector Data in GIS:

• Definition: A spatial data model in GIS that represents geographical features on Earth using discrete geometric coordinate pairs ($X, Y$), classified into three basic topological primitives:
  1. Points: Discrete locations (e.g., wells, city locations).
  2. Lines (Polylines): Linear features (e.g., rivers, roads, railways).
  3. Polygons: Enclosed two-dimensional areas (e.g., lake boundaries, forest parcels, administrative districts).
