Of all of the topics published by RGBDSLAM (I think the correct way to see this is rostopic info /rgbdslam), /rgbdslam/aggregate_clouds seem to be what I'm looking for, but I have encountered a couple problems with this:

With /rgbdslam/aggregate_clouds, Its not publishing anyting when I am doing echo,I am not getting anything.

And is rgbdslam/aggregate_clouds the right topic to subscribe to,If I want full map in rviz to be used by navigation stack?

Thanks.

Since this takes a lot of computation for large maps, you have to trigger it. There's a gui option for sending the model and a ros service call that you can use. See the README -> Usage without GUI

Thanks.One more thing, how to track kinect in gui(localization) while mapping and how to use it for path planning and obstacle avoidance.

The latest pose is send out on the /tf topic. For online path planning and obstacle avoidance you'd probably get better answers from other people. And it depends greatly on your application. Checkout the existing questions and answers or post your own question for your specific use case.

I have also been unable to get the aggregate_cloud to publish. I have tried using the rosservice call /rgbdslam/ros_ui send_all command, however it only publishes the online_coulds and none of the other pointclouds. Any recommendations for getting it to publish the aggregate_cloud?
