The Node can be started either through .launch and via rosrun. It has that classy publish, service server stuff inside Well now when i start the node with rosrun everthing is ok but when i also start rostopic echo /map then i got like only stuff out of an occupancygrid but NOT at the Terminal where i typed the topic command i get it in the terminal where i started my node. after the output the node cancels himself.

If i start with roslaunch then everything works fine....

any idea?

I'm confused. What exactly did you do, got as results, and expected differently?

Well i read a Picture and transfer it into an OccupancyGrid. Then the Publisher gets called which should give it to /map. This should be an alternative for a laserscanner to be able to simulate different cases.
