Make a map

[space03]

Hi. I'm very newbee in ROS.
So I don't know about blam and other things....

I recorded rosbag data and i want to make the 3D Map using this data.

How can i do for making 3D map??

For now,
1st terminal, roslaunch blam_example test_online.launch
2nd terminal, rviz
3rd terminal, rosbag play my_data.bag --clock --topic /velodyne_points

So in Rviz, recorded data is shown but i don't know how to make and save map.

Please help me...

Any of you did solve the problem ? I'm still stuck at the roslaunch blam_example test_online.launch. DOn't understand much aout the difference between the internal and external workspaces and not fiding any documentation or tutorial online...
