Hi there,

You can correct the issue in your example by replacing

var cartesian = scene.pickPosition(movement.endPosition);

``

with

    var ray = viewer.camera.getPickRay(movement.position);
    var cartesian = viewer.scene.globe.pick(ray, viewer.scene);

``

getPickRay will get you a more precise position.

Best,
