Unable to view 3D map on rviz [closed]

edit

I am trying to build ROS and octomap on ubuntu 14.04. These are the steps I follow:

1. I run roscore
2. I launch roslaunch openni_launch openni.launch
3. I launch roslaunch octomap_server octomap_mapping.launch

I have made a few changes to these files after referring the previous issues faced by people and I dont know if its correct.

This is my octomap_mapping.launch file

<launch>
    <node pkg="octomap_server" type="octomap_server_node" name="octomap_server">
        <param name="resolution" value="0.05" />

        <!-- fixed map frame (set to 'map' if SLAM or localization running!)
        <param name="frame_id" type="string" value="odom_combined" /> -->
        <param name="frame_id" type="string" value="map" />

        <!-- maximum range to integrate (speedup!) -->
        <param name="sensor_model/max_range" value="5.0" />

        <!-- data source to integrate (PointCloud2)
        <remap from="cloud_in" to="/narrow_stereo/points_filtered2" /> -->
        <remap from="cloud_in" to="/narrow_stereo/points_filtered2" />

    </node>
</launch>

This is my octomap_mapping_nodelet.launch file

<launch>
  <node pkg="nodelet" type="nodelet" name="standalone_nodelet"  args="manager"/>

  <node pkg="nodelet" type="nodelet" name="octomap_server_nodelet" args="load octomap_server/OctomapServerNodelet standalone_nodelet">
        <param name="resolution" value="0.05" />

        <!-- fixed map frame (set to 'map' if SLAM or localization running!)
        <param name="frame_id" type="string" value="odom_combined" /> -->
        <param name="frame_id" type="string" value="map" />

        <!-- maximum range to integrate (speedup!) -->
        <param name="sensor_model/max_range" value="5.0" />

        <!-- data source to integrate (PointCloud2) -->
        <remap from="octomap_server_nodelet/cloud_in" to="cloud_in" />

      <!-- output collision map -->
      <remap from="octomap_server_nodelet/collision_map_out" to="collision_map_out"/>

    </node>
</launch>

1. I run rosrun rviz rviz

2. I add MarkerArray topic and change the topic to occupied_cells_vis_array (I also tried changing it to occupied_cells_vis but didn't work)

3. I get a fixed frame error: no tf data found. So, I run rosrun tf static_transform_publisher 0.0 0.0 0.0 0.0 0.0 0.0 map my_frame 100 and the error is resolved but still I don't see any maps.

4. I add PointCloud2 topic

I still can't visualize any map. Please please help!
