# Reverse Direction Isoline

This use-case calculates an isoline in the reverse direction. The result is the answer to the question: from where can I get to the destination within a given range? This can be useful to determine which vehicles from a fleet of vehicles (for example, a taxi service) can get to the destination within a given time. To trigger calculation in reverse direction, use the destination parameter instead of origin.
