Angular-Cesium

Drawing

CircleCI npm version

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.

Getting started

If you are using Angular CLI, you can add the angular-cesium library using schematics

Demo

Basic example

For better understading check out the layer guide

Supported Entity types

Map Events

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

Map layers

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>

3d Tiles

   <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>

Multiple maps support

Angular Cesium supports integration of multiple maps, for more details here

MapLayerProviderOptions Updates

MapboxStyleImageryProvider has been added to MapLayerProviderOptions for mapBox styles support.

Component Usage:

  import{ MapLayerProviderOptions } from 'angular-cesium'
  @Component(...)
  class SomeComponent{
    mapboxStyleImageryProvider = MapLayerProviderOptions.MapboxStyleImageryProvider

Template Usage:

<ac-map>
  <ac-map-layer-provider 
  [provider]="mapboxStyleImageryProvider"
  [options]="{
      styleId:'style id from mapbox style dashboard item',
      url:'https://api.mapbox.com/styles/v1/',
      username:'your user name',
      scaleFactor:'@2x',
      tilesize:'512',
      accessToken : 'your access token from map box'
    }">   
  </ac-map-layer-provider> 
</ac-map>

Camera

Camera Keyboard Control Service

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 },
    },

CameraService

Util service that wraps cesium camera, exposes the scene's camera and screenSpaceCameraController.

MapsManagerService

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.

ZoomToRectangleService

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

Geometry Editors And Widgets

Part of AngularCesiumWidgetsModule are useful geometry editors tool:

ScreenshotService

Take screenshot of your cesium globe.

ContextMenuService - stackblitz

create any custom angular component and anchor it to a map position, context menu guide.
