Change location of global costmap relative to map frame / cartographer mark prohibited area

edit

Hi there

I am trying to implement outdoor navigation. When i do so i come to a point where the maps from Google Cartographer do not separate street and meadow good enough. Due to the fact that i want to stay on the street i came up with the idea of editing the map. I do not found a way to edit the .pbstream which is normally the Input for my navigation. To be able to edit a map i run the assets writer, which resulted in a nice map.pgm picture and a map.yaml file. This enables me to edit the map.pgm with normal tools like ImageMagick. Therefore i can draw meadow and other obstacles in this map.

My plan is it still to localize with Cartographer and send the location info over tf to the move_base node. The global_costmap should then initialize on the edited map published with map_server. With enabling the option clearing = false the painted area should stay restricted. to reach that only the /map topic from the map_server gets published is simply commented out cartographer_occupancy_grid_node. This works fine.

The problem is neither the overlapping from the published maps (submaps (black/white right bottom) represents cartographer map, /map (purple right bottom with transparency edited lines) represents the edited map from the map_server) as apparent under visualization of all maps. I simply solved this with changing

origin: [5.51, 8.09, 3.14159] in the map.yaml file...

The problem indeed is, that the global_costmap (purple/turquoise left top) does not adopt its origin an gets published at the [0.0, 0.0, 0.0 ] location. Is there a way to force the global_costmap also to get published at a distinct location (same as the map_server map in the /map frame)? Or do you got any other suggestions to mark the prohibited area with google cartographer?

Thanks in advance
