I have created a first version of a separate node se2_grid_map_generator_node to generate grid_maps to debug the behavior of the planner without the need for any rosbag or simulate sensor. This is useful for the upcoming PR to have online map updates.
It is possible to send messages to the node to modify the map which is then published to a desired topic. See README.
The entire node is very specific for the se2_navigation package. Let me know if you have any ideas how to generalize it. If you think this is useful, we could also add an RViz plugin for it. Similar to the one for se2_navigation package. Maybe we should also use a different name since it does not have any relation to the se2 space...
