how to set max size of map when i generate map using cartographer?

edit

Hi,

i tried to generate a 2D map using cartographer.

it works well when i generate small area, like 30m x 30m length of area. but when i tried to get a map in wide area, it generated a map at first, but as i went to farther and farther, at some point, it didn't draw map anymore. it looks, it can only draw a map in specific size of area.

can i change that specific size of area?

i want to generate wide and huge area, so i need to change max size of generated map.

my environment is

Ubuntu 20.04 ros2-galactic

plz help me! thx :)
