Unable to run demo

[sadu]

Ubuntu 16.04 fresh install with ROS kinetic. I followed steps from readme and while executing the command roslaunch aerial_mapper_demos 0-synthetic-cadastre-dense-pcl.launch the following error message is shown. What could be wrong here? p.s. I am new to ROS/catkin

source ../devel/setup.bash is required after catkin build aerial_mapper to run the demos, fixes my issue

Hi, kindly guide about running custom dataset. My system cant find ROS nodes. Error is here: ERROR: cannot launch node of type [aerial_mapper_demos/aerial_mapper_demos_dense_pcl]: can't locate node [aerial_mapper_demos_dense_pcl] in package [aerial_mapper_demos]

I have set path of dataset in config file

See the previous question. You have to source your workspace after the build.
