## Launch
This package file includes a launch file named spawn_sign.launch which is intended to be included from other launch file that requires to spawn traffic signs in a simulated Gazebo world. This launch file has the following parameters:
***name**: (default=stop1) name given to the traffic sign used to to name the nodes and topics associated with the sign description.
***model**: (default=sign) URDF model to use. At the moment only static traffic signs are supported.
***tag**: (default=alvar0) Name of the Alvar AR tag used to identify the traffic sign.
***type**: (default=stop) Type of the traffic sign. The currently supported types are: giveway, haveway, max_100, max_50, no_entry, no_overtaking, one_way, parking, pedestrian_crossing, roadworks, roundabout, stop, unmarked_intersection and ahead_only.
***x** (default=0.0) x position where the traffic sign will placed in the simulated environment with respect to the parent frame.
***y** (default=0.0) y position where the traffic sign will placed in the simulated environment with respect to the parent frame.
***yaw** (default=0.0) orientation of the traffic sign with respect to the parent frame.
***parent** (default=map) parent reference frame used to place the traffic sign in the simulated environment.
To spawn a traffic sign from an other launch file, include the following lines:
A test launch file is provided to visualize the traffic sign in RVIZ. To use it, execute the following command:
```
roslaunch sign_description spawn_test.launch
```
