Distance-Based Isoline
To calculate a distance-based isoline, specify the distance as rangetype
and range
in meters. mode
can be either shortest or fastest. The driver can arrive at a destination within a certain area by always driving the fastest possible route or by always driving the shortest possible route. The request below calculates a 4km isoline around the center of Berlin in shortest
mode. This results in the answer to the question: What area can I reach by travelling 4km or less?

Drivers normally choose the fastest possible route. It is possible to calculate an isoline which simulates this behavior, while limiting it to a given distance. The request below calculates a 4km isoline around the center of Berlin in fastest
mode. This results in the answer to the question: What area can I reach by travelling 4km or less, while taking the fastest possible route?
