To get the trajectory, you have to initialize hector_trajectory_server node.To do this you can directly call "geotiff_mapper.launch" file in "hector_geotiff" package. After launching this node, to visualize the path in rviz add "Path" and select topic as /trajectory.
Edit:

I did what you told me but i still don't have the path, do i need to set any parameter on "geotiff_mapper.launch" file ?
Comment by gp on 2016-05-25:
Can you please share your launch files or elaborate what procedure you are following. In "geotiff_mapper.launch" file, you will need to set argument "trajectory_source_frame_name" to tf for which you want to visualize the path.
