It is not shown in rqt_graph the service call connection for SelfLocalizer node to where ? From rosnode info SelfLocalizer it shows

* /SelfLocalizer/get_loggers
 * /SelfLocalizer/set_logger_level

Are they from MapServer node ? And what does MapServer node do, because is is not in Nav2d package ?

afaik mapserver publishes the map as it is (occupancy grid). The localization happens with other algorithms, like AMCL for example.

Yes it is, but service connections are not shown in rqt_graph. You can use "rosservice list" to show the available services, but this will also not show which node is calling these services.

The MapServer is from the ros-navigation stack:

Thanks for confirming that.
