Overview
The Isochrones API calculates the area that a person can reach from a specific
origin point within a set amount of time. Unlike a radius, which measures a
straight-line distance, an isochrone accounts for actual road network travel
times to create a polygon that represents true reachability.
Common use cases include:
- Delivery logistics: Determine which customers are servable within 30 minutes of a warehouse.
- Real estate: Find properties within a 45-minute commute of a workplace.
- Urban planning: Analyze the accessibility of essential services like hospitals or grocery stores.
To get started, see Set up the Isochrones API.
