Spawn service timed out, sdf model deprecated?

edit

I am trying to launch a model to gazebo, but it failed with the following message:

Deprecated: the -gazebo tag is now -sdf
[INFO] [WallTime: 1474618632.137629] [0.000000] Loading model xml from ros parameter

I noticed it said "Deprecated: the -gazebo tag is now -sdf" and "SpawnModel: Model pushed to spawn queue, but spawn service timed out waiting for model to appear in simulation under the name land_station1"

I googled the error and found someone having same prob with me HERE

and it said that the problem is because: the urdf had some deprecated functions from old versions of gazebo.

Iam new to gazebo. Appreciate if you can help me to correct the sdf model:
