How to: Calculate an Isochrone by Time

The following example plots a polygon that shows the area that is accessible from the specified point. The size of the area depends on a given travel time (the time is equal to 10 minutes in the example below):

Time-based isochrone

            // Call the ZoomToFitLayerItems method to zoom the map so that it displays the created isochrone.
