Use Cesium in the real angular way!
bower install angular-cesium
Using angular-cesium is easy as pie! Just add it as a dependency:
angular.module('myModule', ['angularCesium']);
And start using the map components!
<map>
<web-map-service-layer ng-repeat="layer in layers" url="layer.url" layers="layer.layers"></web-map-service-layer>
<billboards-layer>
<billboard ng-repeat="billboard in billboards"
image="billboard.image"
color="billboard.color"
position="billboard.position"></billboard>
</billboards-layer>
</map>
