How to change costmap orientation-z ?

edit

I have changed my map.yaml params.

image: /home/jason/catkin_ws/src/robot_localization/maps/map.pgm
resolution: 0.050000
origin: [-110, 11, -1.57]
negate: 0
occupied_thresh: 0.65
free_thresh: 0.19

the orientation is -1.57.

but when I load global costmap

my global costmap params:

obstacle_range: 2.5
raytrace_range: 3.5
footprint: [[-0.5, -0.5], [-0.5, 0.5], [0.5, 0.5], [0.5, -0.5]]
#robot_radius: 0.105

cost_scaling_factor: 0.5
map_type: costmap
transform_tolerance: 0.2
global_costmap:
  global_frame: /map
  robot_base_frame: /base_footprint
  update_frequency: 2.0
  publish_frequency: 0.1
  static_map: true
  transform_tolerance: 1.0
  plugins:
    - {name: static_map,      type: "costmap_2d::StaticLayer"}
    - {name: inflation_layer, type: "costmap_2d::InflationLayer"}
  inflation_layer:
    inflation_radius: 0.65
