Set up elevation mapping with ouster 1-128

[youweik2]

I'm a little confused about how to setup the elevation mapping parameters with ouster 1-128 lidar. So we try to change the pointcloud topic to the topic that our driver published. But it doesn't work. It seems that ouster is using pointcloud2 but the elevation map only takes pointcloud. How to do the conversion between these 2 different type?
