<ion-content>
  <div #map id="map"></div>  
</ion-content>

and my map.tas contains following code

import { Component, ViewChild, ElementRef } from '@angular/core';
import { IonicPage, NavController, NavParams } from 'ionic-angular';
import { Geolocation } from '@ionic-native/geolocation';

declare var google;

@IonicPage()
@Component({
  selector: 'page-google-map',
  templateUrl: 'google-map.html',
})
export class GoogleMapPage {
  @ViewChild('map') mapElement: ElementRef;
  map: any;

  constructor(public navCtrl: NavController, public navParams: 
NavParams,public geolocation: Geolocation) {
  }

  ionViewDidLoad() {
    console.log('ionViewDidLoad GoogleMapPage');
    this.loadMap();
  }

  loadMap(){

this.geolocation.getCurrentPosition().then((position) => {

  let latLng = new google.maps.LatLng(position.coords.latitude, position.coords.longitude);

  let mapOptions = {
    center: latLng,
    zoom: 15,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  }

  this.map = new google.maps.Map(this.mapElement.nativeElement, mapOptions);
  this
}, (err) => {
  console.log(err);
});

  }
      addMarker(){

    let marker = new google.maps.Marker({
      map: this.map,
      animation: google.maps.Animation.DROP,
      position: this.map.getCenter()
    });

    let content = "<h4>Information!</h4>";          

    this.addInfoWindow(marker, content);

  }
      addInfoWindow(marker, content){

    let infoWindow = new google.maps.InfoWindow({
      content: content
    });

    google.maps.event.addListener(marker, 'click', () => {
  infoWindow.open(this.map, marker);
    });

  }
 }
