Map 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, enabling maps to display more information.

Adding Multiple Layers in the Map

The shape layers is the core layer of the map. The multiple layers can be added in the shape layer type as SubLayer.


In this example, 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\

You can assign the complete contents in WorldMap.json file to new JSON object. For better understanding, a TS file WorldMap.ts is already created to store JSON data in JSON object “worldmap” and also copy the USA.json file data, bind value to “usMap” like “worldmap”.


export let world_map = //Paste all the content copied from the JSON file//


export let usMap = //Paste all the content copied from the USA.JSON file//

Note: USA Map rendered as a sublayer using layer.type as “SubLayer”.
