Topological relationships describe relationships between objects in space. By objects we mean natural or manmade features like lakes, trees, houses, roads, etc. Important topological relationships are explained below:
- Proximity describes how close or how far away two (or more) objects are - my school is near my house.
- Connectivity means how two objects are linked with each other the downtown is connected with a subway.
- Adjacency explains whether two objects are next to each other or not - Tom’s house is next to Pam’s.
- Membership means whether an object belongs to a particular group or not apple is a type of fruit.
- Orientation describes the location and direction of an object - the house is located 10 miles north of the city
Topological relationships support map reading and allow important spatial decisions.
