Topology, in spatial data, records

  • A.how features connect and adjoin one another
  • B.the exact coordinates of every single vertex
  • C.the colours used when drawing each feature
  • D.the projection in which the data are stored

Answer: A

Connectivity, adjacency and containment are stored explicitly, so the software knows that two districts share a boundary rather than merely having lines that happen to coincide. This is what makes network and overlay analysis possible.
