Currently this information is available only for those surveys that specifically provide it.  Planned Data Lab enhancements include MOC (Multi-Order Coverage) services that can be used to provide footprints of surveys or particular result sets, and more detailed column statistics for tables that might be useful in providing depth information.  Crude estimates of coverage/depth can sometimes be obtained using just the min/max functions in your SQL query.
