grid_map_msgs¶

Message types¶

• grid_map_msgs/GridMapInfo
• grid_map_msgs/GridMap

grid_map_msgs/GridMapInfo¶

Field:	header (std_msgs/Header) – resolution (float64) – length_x (float64) – length_y (float64) – pose (geometry_msgs/Pose) –

Header (time and frame)

# Header (time and frame)
Header header

# Resolution of the grid [m/cell].
float64 resolution

# Length in x-direction [m].
float64 length_x

# Length in y-direction [m].
float64 length_y

# Pose of the grid map center in the frame defined in `header` [m].
geometry_msgs/Pose pose

grid_map_msgs/GridMap¶

Field:	info (grid_map_msgs/GridMapInfo) – layers[] (string) – basic_layers[] (string) – data[] (std_msgs/Float32MultiArray) – outer_start_index (uint16) – inner_start_index (uint16) –

Grid map header

# Grid map header
GridMapInfo info

# Grid map layer names.
string[] layers

# Grid map basic layer names (optional). The basic layers
# determine which layers from `layers` need to be valid
# in order for a cell of the grid map to be valid.
