its working , thank you a lot , you saved me

no, I didn't . i don't see any path with rviz

first i run the file of hokuyo and hector_mapping that i obtained here

https://github.com/DaikiMaekawa/hecto...

and than i run the launch file provided in the hector_mapping package

<launch> <arg name="trajectory_source_frame_name" default="/base_link"/> <arg name="trajectory_update_rate" default="4"/> <arg name="trajectory_publish_rate" default="0.25"/> <arg name="map_file_path" default="$(find hector_geotiff)/maps"/> <arg name="map_file_base_name" default="hector_slam_map"/>

<node pkg="hector_trajectory_server" type="hector_trajectory_server" name="hector_trajectory_server" output="screen"> </node>

<node pkg="hector_geotiff" type="geotiff_node" name="hector_geotiff_node" output="screen" launch-prefix="nice -n 15"> <remap from="map" to="/dynamic_map"/> </node>

</launch<>

hi, please how did you do to see the trajectory on rviz??

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 ?
