Class: Isochrone

cercaliagl.service/Isochrone


Javascript ES5

const isochroneService = new cercaliagl.service.Isochrone({ ... });

This class offers the service of calculating isochrones given an origin point, weight and value.<br/< It also allows to obtain a detailed or simpler geometry.

Example usage:

const isochroneService = new cercaliagl.service.Isochrone({
  position: new cercaliagl.LonLat(2.153665978, 41.395293973);
  weight: cercaliagl.service.Isochrone.Weight.DISTANCE,
  method: cercaliagl.service.Isochrone.Methods.DETAILED,
  isolevels: 20000
});

isochroneService.calculate((data) => {
  const wkt = data.cercalia.isochrones.isochrone.value;
  const feature = new cercaliagl.Feature({
    wkt: wkt
  });
  map.addFeature(feature);
  map.centerToFeatures([feature]);
});

weight string

Proximity with real route distance. Possible values: time, distance, money.
inverse boolean

Can be true or false. With a false value, the distances are calculated from the reference to the target. With a true value, the distances are calculated from the references to the targets. The default is false.
method string

Calculation method. Por defecto: convexhull or concavehull. Default value convexhull.
isolevels number

Value, or incremental values list used for isochrone calculation (meters or miliseconds). Ex: 10000, 5000,10000,20000.
net string

Calculation net. Possible values: car, bike, foot. Default value car.
