Zooming
The zooming feature is used to zoom in and out of Maps to show in-depth information. It is controlled by the ZoomFactor property of the MapsZoomSettings of the Maps. The ZoomFactor is increased or decrease dynamically based on zoom in and out interaction.
Enable zooming
Zooming of Maps is enabled by setting the Enable property of MapsZoomSettings to true.
Enable panning
To enable the panning feature, set the EnablePanning property of MapsZoomSettings to true.

}Various type of zooming
Zooming can be performed in following types:
Zooming toolbar
By default, the toolbar is rendered with zoom-in, zoom-out, and reset options when it is set to true in the Enable property of MapsZoomSettings.
The following options are available in toolbar.
- Zoom - Provides rectangular zoom support.
- ZoomIn - Zoom in the Maps.
- ZoomOut - Zoom out the Maps.
- Pan - Switches to panning if rectangular zoom is activated.
- Reset - Restores the Maps to the default view.

Enable selection for polygons
When the enable property of selectionSettings is set to true, the polygon shapes can be selected via user interaction. The following properties are available in selectionSettings to customize the polygon shape when it is selected.
- enableMultiSelect - It is used to enable multiple selection of polygon shapes.
- fill - It is used to change the color of the selected polygon shape.
- opacity - It is used to change the opacity of the selected polygon shape.
- border - This property is used to change the color, width, and opacity of the border of the selected polygon shape.
The following example shows how to select the polygon shape in the geometry map.

Tooltip
On mouse over or touch end event, the tooltip is used to get more information about the layer, bubble, or marker. It can be enabled separately for layer or bubble or marker by using the Visible property of MapsTooltipSettings as true. The ValuePath property in the tooltip takes the field name that presents in data source and displays that value as tooltip text. The TooltipDisplayMode property is used to change the display mode of the tooltip in Maps. Following display modes of tooltip are available in the Maps component. By default, TooltipDisplayMode is set to MouseMove.

Changing duration in mobile devices
To change the duration of the tooltips and tooltip templates in mobile devices, you can use the Duration property in MapsTooltipSettings. By default, this property is set to 2000 milliseconds. Setting the value to 0 will keep the tooltip visible indefinitely. If it is greater than 0, the tooltip will be removed after the specified time.
@using Syncfusion.EJ2.Maps;
@{
var tooltip = new Syncfusion.EJ2.Maps.MapsTooltipSettings

Visible = true,

Fill = "#D0D0D0",
TextStyle = new MapsFont
{
Color = "green",
FontFamily = "Times New Roman",
FontStyle = "Sans-serif"
},
Duration = 3000
};
