Navigation line in EJ2 TypeScript Maps control

27 Apr 20237 minutes to read

The navigation lines are used to denote the path between two locations. This feature can be used to draw flight or sea routes. Navigation lines are enabled by setting the visible property of the navigationLineSettings to true. To render the navigation line in Maps, NavigationLine Module must be injected into the Maps using the Maps.Inject(NavigationLine) method.

import { Maps, NavigationLine } from '@syncfusion/ej2-maps';
Maps.Inject(NavigationLine);
let map: Maps = new Maps({ });

Customization

The following properties are available in navigationLineSettings to customize the navigation line of the Maps component.

color - To apply the color for navigation lines in Maps.
dashArray - To define the pattern of dashes and gaps that is applied to the outline of the navigation lines.
width - To customize the width of the navigation lines.
angle - To customize the angle of the navigation lines.
highlightSettings - To customize the highlight settings of the navigation line.
selectionSettings - To customize the selection settings of the navigation line.

To navigate the line between two cities on the world map, latitude and longitude values are used to indicate the start and end points of navigation lines drawn on Maps.
