Calculate an isochrone to target your customers

Imagine you are a store owner and like to target customers that live within a 15-minute drive from your store. You could draw a circle on a map, but it will not tell you the time it will take for the customer to get to your store. For example, a customer living near a motorway can live further away from the store than a customer living on the other side of the city. An isochrone is a curve (an area on a map) of equal travel time representing the travel time it will take to get to a specific point (your store, in this case). Calculating an isochrone correctly, including all the variables like traffic, road, and vehicle conditions, is very hard to do by yourself.



Using the Get Route Range API from Azure Maps makes it very easy to calculate the isochrone. For our store example, we need to calculate a 15-minute isochrone for every store we have. We only need the coordinates (longitude and latitude) from our stores and the drivetime in seconds (15 x 60 = 900 sec).



Search Customer Address

To determine which customer is living inside the 15-minute drive isochrone, we first need the coordinates for every customer’s address. Then, we simply loop through all our customers and use the Get Search Address API to get the coordinates.

GET[subscription-key]&api-version=1.0&query=15127 NE 24th Street, Redmond, WA 98052

Point In Polygon

The last step is to check if a customer coordinate is inside one of our store isochrones. We use the Point In Polygon API to determine if this is true.



And in the request body the store isochrone.


We now can target those customers with store-specific offers and promotions.



What schools are within a 20-minute walk from my home? What available jobs are within a 30-minute transit commute? Where you are located and what is near you brings context to the choice of where you want to live and Azure Maps Isochrone API can help you bring that location intelligence into your applications.
