Simple way to get camera position?

MeganWirth — Tue, 08 Nov 2016 14:47:35 GMT

Is there a simple way to set a scenes camera position? i.e. Lat, long, z, heading, and tilt? I ask because i spend a lot of time trying to set these parameters in the api.

Ryan,

Sure use:

// Clone the camera to modify its properties
var camera = view.camera.clone();

// Set new values for heading and tilt
camera.heading = 180;
camera.tilt = 45;

// Set the new properties on the view's camera
view.camera = camera;‍‍‍‍‍‍‍‍‍

Thanks for the reply Robert hope all is well with you.

I believe I need to rephrase the question. Is it possible to be able to pan, tilt and zoom a scene manually and then be able to see the camera parameters so that you can set the camera position values for the camera? Sorry hard to explain ha

Ryan,

Ok, now I understand. You can use your browsers developer tools to watch the cameras properties:

The other way to do it is in the code. You can set up watches on different properties

      var view = new SceneView({
        container: "viewDiv",
        map: map,
        scale: 50000000,
        center: [-101.17, 21.78]
      });

      view.watch('camera.tilt', function(newValue, oldValue, property, object) {
          console.log(property , newValue);
      });
    });
