A map of the New York City Subway, an example of a topological map.
An office environment consisting of two rooms connected by a hallway. A topological map is super-imposed.
In cartography , geology , and robotics ,[ 1] a topological map is a type of diagram that has been simplified so that only vital information remains and unnecessary detail has been removed . These maps lack scale, also distance and direction are subject to change and/or variation, but the topological relationship between points is maintained. A good example are the tube maps for the London Underground and the New York City Subway .[ 2]
