The maps is maintained through layers, and it can accommodate one or more layers.
The multilayer support allows you to load multiple shape files in a single container. This enables maps to display more information.
The shape layers are the core layers of a map. The multiple layers can be added in the shape layers as subLayers within the shape layers.
The subLayer is the collection of shape layers.
In this example, the world map shape is used as shape data by utilizing the “WorldMap.json” file in the following folder structure obtained from downloaded Maps_GeoJSON folder.
..\ Maps_GeoJSON\
Refer both shape data and shape settings as illustrated in the following code example.
@using Syncfusion.EJ2;
@Html.EJS().Maps("maps").Layers(l =>
{
l.ShapeSettings(ss =>ss.Fill("#9CBF4E").Border(border => border.Color("white").Width(0.5)))
.ShapeData(ViewBag.worldMap).Add();
l.ShapeSettings(ss => ss.Fill("orange").Border(border => border.Color("white").Width(1)))
.ShapeData(ViewBag.usMap).Add();
}).Render()using System;
