This code list is used in association with the Physical Level attribute which is present within multiple OS NGD feature types across various OS NGD themes. The code list describes the physical level of the feature, for example, 'Surface Level' or 'Level 1' if the feature is on a supported structure.

Label	Definition
Level 1	Physical level of the feature, for example 'Surface level' or 'Level 1', if it is on a supported structure.
Level 2	Physical level of the feature, which is above a 'Level 1' supported structure.
Level 3	Physical level of the feature, which is above a 'Level 1' supported structure.
Overhead	Physical level for features captured overhead. These features do not interact with the topology of the features captured at other physical levels.
Surface Level	Physical level where ground surface level is the lowest identifiable level that is not underground.
