Stores the options that are used to calculate an isochrone.

Namespace: DevExpress.XtraMap

Assembly: DevExpress.XtraMap.v24.2.dll

Declaration

public class BingRouteIsochroneOptions :
    MapNotificationOptions

VB.NET

Public Class BingRouteIsochroneOptions
    Inherits MapNotificationOptions

Related API Members

The following members return BingRouteIsochroneOptions objects:

• BingRouteIsochroneDataProvider.IsochroneOptions

Remarks

You can specify the following options for distance-based isochrones (refer to CalculateIsochroneByDistance for more information):

• Mode
• DistanceUnit

You can specify the following options for time-based isochrones (refer to CalculateIsochroneByTime and CalculateIsochroneByTimeWithTraffic for more information):

• Mode
• TimeUnit

Example

The following code 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 (10 minutes in the example below):

• Create an InformationLayer object and add it to the MapControl.Layers collection.

• Initialize the layer’s InformationLayer.DataProvider property with a BingRouteIsochroneDataProvider object.

• Specify the adapter’s BingKey property.

• Optional. Define the Mode and TimeUnit parameters.

• Call the CalculateIsochroneByTime method to calculate an isochrone.
