Hi Yogitha, 
 
You can add google maps in SfMaps control. Please refer the following Kb. 
 
 
Please find the following UG link for more information.

Hi Yogita, 
 
To display the google street map view, you can assign the given google map Url of “lyrs” value is “m” as shown in below code. 
 
        private void ImageryLayer_RequestTileUri(object sender, Syncfusion.SfMaps.XForms.TileUriArgs e) 
        { 
            var link = "http://mt1.google.com/vt/lyrs=m&x=" + e.X.ToString() + "&y=" + e.Y.ToString() + "&z=" + e.ZoomLevel.ToString(); 
            e.Uri = link;          
        } 
 
Likewise, you can change to the other view type by assigning the below layer value. 
  
h = roads only 
m = standard roadmap (street map) 
p = terrain 
r = somehow altered roadmap 
s = satellite only 
t = terrain only 
y = hybrid 
  
Please find the sample link from below location.

Regards, 
Ramya.

Hi Yogita, 

Thanks for your response. 

Currently SfMaps does not have direct support to achieve your requirement. So, we have achieved this requirement in sample level by calculating the bounds of the Markers collection. From that Marker bounds, calculated the center, ZoomLevel values and set those values to GeoCoordinate and ZoomLevel property of SfMap. Please find the snippet from below. 

[C#]: 
… 
private void AddMarkersButton_OnClicked(object sender, EventArgs e) 
{ 
    this.AddMarker(); 
} 
… 
private void AddMarker() 
{ 
    this.imageryLayer.Markers.Add(new CustomMarker { Latitude = "22.787998", Longitude = "72.539067" }); 
    this.imageryLayer.Markers.Add(new CustomMarker { Latitude = "22.589499", Longitude = "75.842287" }); 
    this.imageryLayer.Markers.Add(new CustomMarker { Latitude = "22.122114", Longitude = "85.158694" }); 
    this.imageryLayer.Markers.Add(new CustomMarker { Latitude = "17.213389", Longitude = "78.457033" }); 
    this.imageryLayer.Markers.Add(new CustomMarker { Latitude = "10.259969", Longitude = "77.512209" }); 
 
    this.CalculateZoomLevel(this.imageryLayer.Markers); 
} 
… 
// Calculate the ZoomLevel based on the Markers collection. 
private void CalculateZoomLevel(ObservableCollection<MapMarker> markers) 
{ 
    CalculateMarkerBounds(markers, out Point northEast, out Point southWest); 
    var center = new Point((northEast.Y + southWest.Y) / 2, (northEast.X + southWest.X) / 2); 
    var northEastWithPadding = new Point(northEast.X + ((northEast.X - center.X) / 2), northEast.Y + (northEast.Y - center.Y) / 2); // added half distance as padding for north east 
    var southWestWithPadding = new Point(southWest.X - (center.X - southWest.X) / 2, southWest.Y - (center.Y - southWest.Y) / 2); // added half distance as padding for south west 
    var zoomLevel = GetBoundsZoomLevel(northEastWithPadding, southWestWithPadding, sfMaps.Width, sfMaps.Height); 
 
    if (this.sfMaps.ZoomLevel == zoomLevel) 
    { 
        this.sfMaps.ZoomLevel = 1; // reset the zoom level value in order to update the property 
    } 
 
    sfMaps.ZoomLevel = zoomLevel; 
 
    if (imageryLayer.GeoCoordinates == center) 
    { 
        this.imageryLayer.GeoCoordinates = new Point(0, 0); // reset the center value in order to update the property 
    } 
 
    imageryLayer.GeoCoordinates = center; 
}… 

Please find the sample from the below location. 

Already, we have logged feature request for the above requirement, and you can track from the below feedback report link.   


It will be available in our upcoming volume 2020 Volume 1 release which is scheduled to be rolled out by March 2020. We appreciate your patience until then.  

Please continue with the above workaround until our 2020 volume 1 release. 

Regards, 
Vignesh.
