I'm new to ROS, I'm trying to create a map with V-REP USING hector_slam, but I'm not able to make the map appear on rviz, can someone help me?

edit

Hi, there is way to little information in your post to really help you. Is the map server working is rviz configured? In rviz there is a section where you can add for example topics you can choose in the dialog to show availabe data, if your map is there just ad it. However as I said most likely its more complex.

Please help me, I need to do this scene for my course completion work, I've tried everything

I'm trying to create the transformation tree by V-REP, I'm using the rosinterface, but when I create the tree and run it, roslaunch hector_slam_launch autonomo.launch, it opens the rviz, but it doesn't show the map, nor the laser data, Could you help me?

This is the link to the moon code, if you prefer I can share everything from catkin_ws

i need help

Maybe rviz just isnt configured, post a screenshot. what does "rostopic list" show? what does "rosnode list" show? Post the screenshots.

rostopic list /map /clicked_point /clock /cmd_vel /initialpose /move_base_simple/goal /odom /rosout /rosout_agg /scan /tf /tf_static

Need more info, as I said maybe its just rviz isnt configured to show the map, or the map is Null and there is just nothing to see yet etc...
