Time Map Simple (Isochrones)anchor icon

Summaryanchor icon

This tool creates isochrones, also known as travel time polygons or catchment areas. It visualises all the locations that are reachable within a time limit based on selected parameters including transport mode & departure/arrival time.

Only the key parameter fields are configurable. The more complex parameter fields (available in the Advanced tool) take standard, sensible values.
