I'm working on the tutorial "ROS Autonomous Vehicles 101". In chapter 2 (Sensors) I follow the steps to get the AerialMapDisplay loaded, but RVIZ gives the error "Failed to create cache folder [..]" (see alt text)

I guess it is due to missing access rights on this folder. Does there exist any workaround?

Hi,

Its due to the fact that its using the installed version of the rviz_satellite ROS package where you dont have access. To solve this you just have to do the following:

  • Step 1)

    roscd catvehicle

    cp -r rviz_config /home/user/catkin_ws/src/

    cd /home/user/catkin_ws/src/

    chown -R user:theconstruct rviz_config

  • Step 2) Then you download the rviz_satellite package and source it so that when we run rviz in this shell it gets that package, and not the one installed in the system to avoid permission issues. The problem was that the rviz was trying to write in that package that is installed in the system, and therefore you didn't have permissions as user to modify it.

    cd /home/user/catkin_ws/src/

    git clone https://github.com/gareth-cross/rviz_satellite.git

    cd /home/user/catkin_ws

    source devel/setup.bash

    rosapck profile

  • Step3) Launch the RVIZ and load the file in rviz_config/catvehicle_gps.rviz

You should then get something like this:
