Isochrones

Isochrones, by car

Request:

Example:

&cmd=isochrone&weight=time&mocs=4326&ocs=4326&mo=2.8260807,41.9723144&isolevels=120000,300000,600000&method=concavehull&net=esp

Where:

• cmd=isochrone request type (isochrone)
• mo= coord X,Y isochrone center point
• mocs / ocs= coordinate system (4326 = geog lat,long)
• weight= isochrone calculation type: driving time (time) / maximum distance (distance)
• isolevels= isochrones values. You can add several isochrones in a single request.
  • weight=time value in milliseconds
  • weight=distance value in meters
• method= isochrone type:
  • convexhull: simplified shape isochrone
  • concavehull: improved shape isochrone
• net= logistics (only for truck routing)

* Rest of parameters, add them with the values ​​indicated in the example
