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):

• 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 provider’s BingKey property.

• Define the Mode and TimeUnit parameters.

• Call the CalculateIsochroneByTime method to calculate an isochrone.

C#

using System.Windows.Forms;

namespace IsochroneSample {
    public partial class Form1 : Form {

        private void Form1_Load(object sender, EventArgs e) {
            ImageLayer imageLayer = new ImageLayer();
            mapControl1.Layers.Add(imageLayer);
            BingMapDataProvider provider = new BingMapDataProvider();
            provider.BingKey = "Insert your Bing key.";
            provider.Kind = BingMapKind.RoadLight;
            imageLayer.DataProvider = provider;

            InformationLayer infoLayer = new InformationLayer();
            mapControl1.Layers.Add(infoLayer);

            BingRouteIsochroneDataProvider isochroneDataProvider = new BingRouteIsochroneDataProvider();
            isochroneDataProvider.BingKey = "Insert your Bing key.";
            GeoPoint origin = new GeoPoint(36.1532403246368, -86.7701703811725);
            mapControl1.CenterPoint = origin;
            isochroneDataProvider.IsochroneOptions.TimeUnit = TimeMeasureUnit.Minute;
            isochroneDataProvider.IsochroneOptions.Mode = BingTravelMode.Driving;
            isochroneDataProvider.CalculateIsochroneByTime(new RouteWaypoint("", origin), 10);
            infoLayer.DataProvider = isochroneDataProvider;

            infoLayer.DataRequestCompleted += OnDataRequestCompleted;
        }

        private void OnDataRequestCompleted(object sender, RequestCompletedEventArgs e) {
            // Call the ZoomToFitLayerItems method to zoom the map so that it displays the created isochrone.
            mapControl1.ZoomToFitLayerItems();
