          }, {

            alias: "name",

            type: "string"

          }],

        title:"Vehiculos de serenazgo",

        objectIdField: "ObjectID", 

        geometryType: "point", 

        spatialReference: { wkid: 4326 },

        popupTemplate : {

          title: "Hola",

            content: "<b>Objectid:</b> {ObjectID}<br><b>Nombre:</b>{name}<br>"

         },

       renderer: {

          type: "simple",

          symbol: {

            type: "simple-marker",

      }); 

function getJSON(){

        fetch('https://www.datos.gov.co/resource/g373-n3yy.json')

        .then(response => response.json())

        .then(locations => {

            var i=1;

            var features = [];

            locations.forEach(location => {

                features.push(new Graphic({

                  geometry: {

                    type: "point",

                    latitude: location.punto.coordinates[1],

                    longitude: location.punto.coordinates[0]

                  },

                  attributes: {

                    ObjectID: i,

                    name: location.nombre_sede

                  }

                }));                

                i++;

            });

            serenazgo.source=features;            

            map.remove(serenazgo);

            map.add(serenazgo);                        

        })

       }

       mapView

          .when()

          .then(getJSON)

          .catch(function (e) {

            console.error("Creaacion de feature de serenazgo fallo ", e);

          });

       //Llama al servicio de GPS 

       setInterval(getJSON,5000);

       // Fin de la funcion
