Create amazing mapping applications using Cesium and Angular components. Angular-Cesium is focused on high performance and simple usage. Check out our Docs and our blog post Intro to angular-cesium.
- add
angular-cesium
:$ ng add angular-cesium
Manual installation details here.
- You can try and learn about angular-cesium from our demo.
- The demo contains many examples, check out the
demo-map.component.ts
file. - Run:
$ git clone https://github.com/articodeltd/angular-cesium.git $ cd angular-cesium $ yarn $ yarn demo:start $ open http://localhost:4200

In your HTML file :
<ac-map> <ac-layer acFor="let plane of planes$" [show]="showTracks" [context]="this"> <ac-billboard-desc props="{ image: plane.image, position: plane.position }"> </ac-billboard-desc> <ac-label-desc props="{ position: plane.position, text: plane.name }"> </ac-label-desc> </ac-layer> </ac-map>
-
ac-map
creates the map -
ac-layer
component represent an array of entities that will be displayed on the map.acFor
attribute accepts an RxObserverplanes$
,ac-layer
will subscribe to the observer and will handle all updates for you.
-
Add descriptions components to determine which entity to render, in our example:
ac-billboard
andac-label
.- This example will render a billboard(icon) and label for each plane in the stream.
props
accepts the same member options as cesium corresponding class. For exampleac-billboard-desc
accepts same members as cesium Billboard.

MapEventsManagerService
is a util service for managing all the map events (Click, Mouse_up...), it expose easy API for entity selection, event priority management
and adds custom events (drag and drop, long press).
Usage:
@Component(...)
export class SomeComponent{
constructor(private eventManager: MapEventsManagerService){
// Input about the wanted event
const eventRegistration: EventRegistrationInput = {
event: CesiumEvent.LEFT_CLICK, // event type enum. [required!]
modifier: CesiumEventModifier.CTRL, // event modifier enum. [optional]
entityType: AcEntity, // raise event only if AcEntity is clicked. [optional]
priority: 0, // event priority, default 0 . [optional]
pick: PickOptions.PICK_FIRST // entity pick option, default PickOptions.NO_PICK. [optional]
};
const clickEvent = this.eventManager.register(eventRegistration).subscribe((result) => {
// The EventResult will contain:
// movement(screen location of the event), entities(your entities) , primitives( cesium primitives, like label,billboard...)
console.log('map click', result.movement, 'primitives:', result.primitives, 'entities', result.entities);
});
}
}
For further details check the map events guide
With angular cesium you can define your map provider in a declarative way using ac-map-layer-provider
:
<ac-map-layer-provider *ngIf="appSettingsService.showMapLayer" [provider]="MapLayerProviderOptions.ArcGisMapServer"
[options]="{
url : 'https://server.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer'
}">
</ac-map-layer-provider>
- All cesium imagery map layers are supported , defined with
[provider]
according to theMapLayerProviderOptions
enum - Pass additional configuration to
[options]
.url
is mandatory. - Support multi map layers, map ordering and map image layer configuration.
- Check out usage example from our demo here
<ac-3d-tile-layer
*ngIf="appSettingsService.show3dtiles"
[options]="{
url: 'https://beta.cesium.com/api/assets/1461?access_token=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJqdGkiOiJkYWJmM2MzNS02OWM5LTQ3OWItYjEyYS0xZmNlODM5ZDNkMTYiLCJpZCI6NDQsImFzc2V0cyI6WzE0NjFdLCJpYXQiOjE0OTkyNjQ3NDN9.vuR75SqPDKcggvUrG_vpx0Av02jdiAxnnB1fNf-9f7s'
}">
</ac-3d-tile-layer>
Angular Cesium supports integration of multiple maps, for more details here
Service that manages keyboard keys and execute actions per request. Inject the keyboard control service into any layer, under your ac-map component, And defined you keyboard handlers using setKeyboardControls.
this.keyboardControlService.setKeyboardControls({
W: { action: KeyboardAction.CAMERA_FORWARD },
S: { action: KeyboardAction.CAMERA_BACKWARD },
D: { action: KeyboardAction.CAMERA_RIGHT },
A: { action: KeyboardAction.CAMERA_LEFT },
},
Util service that wraps cesium camera, exposes the scene's camera and screenSpaceCameraController.
Angular Cesium extends cesium api and expose additional features, but if you want to use pure cesium api you can use MapsManagerService to receive cesium viewer or any other util service that was created by ac-map
.
class MyComp {
constructor(mapsManagerService: MapsManagerService)
const viewer = mapsManagerService.getMap().getCesiumViewer();
const mapEventManager = mapsManagerService.getMap().getMapEventsManager();
const cameraService = mapsManagerService.getMap().getCameraService();
}
MapsManagerService
manages all of the maps. The service exposes a getMap()
function that can be used to retrieve a specific map by id.
A service that is used to activate a zooming tool that enables the user to draw a rectangle over the map and zoom into the drawn rectangle
