Instructions:
1. Use approximate location control on the map to change initial approximation for the algorithm.
2. Place at least 3 markers on the 3D model (ctrl+click) - drag to position more precisely.
3. Move all markers on the map to update their location - drag to position more precisely.
4. Click this button - the results will appear in a dialog window with "apply"/"cancel"
5. To save the result click upload button (Initial location and heading) in the menu.' class='edit'></div>
