Zero lies in z=0.0m in your global map frame, however you arrange that with tf. That depends on where and how you built your map. Of course all units are meters as it is the standard in ROS.
When you slice with occupancy_min/max_z, make sure that the interval is large enough to hold one voxel, i.e., larger than the octree file resolution.
