sec.5Defining a stratum lot

### sec.5 Defining a stratum lot A stratum lot must be defined by regular planes, that may be horizontal or inclined, fixed by reference to levels in relation to Australian height datum. If a stratum lot is defined by an inclined plane, elevations or sections must be shown, identifying the plane with enough information to enable the level of any point on the plane to be calculated. A stratum lot must be illustrated in orthographic form or isometric form. In this section— Australian height datum means the Australian height datum adopted by the National Mapping Council of Australia for referencing a level or height back to a standard base level. (sec.5-ssec.1) A stratum lot must be defined by regular planes, that may be horizontal or inclined, fixed by reference to levels in relation to Australian height datum. (sec.5-ssec.2) If a stratum lot is defined by an inclined plane, elevations or sections must be shown, identifying the plane with enough information to enable the level of any point on the plane to be calculated. (sec.5-ssec.3) A stratum lot must be illustrated in orthographic form or isometric form. (sec.5-ssec.4) In this section— Australian height datum means the Australian height datum adopted by the National Mapping Council of Australia for referencing a level or height back to a standard base level.
