Feature code lookup table

This table gives descriptions for each feature code value. The feature code itself is arbitrarily assigned and so carries no information without this table.

In the 'Descriptive term' column, a blank box means multiple, other, or none. This code is used for features with multiple descriptive terms, with no descriptive term, or with one descriptive term that does not have its own feature code.

The column 'Feature type' has been abbreviated by omitting the words topographic, boundary and cartographic from the feature type names. Where ‘Line’ appears in this column, it includes both TopographicLine and BoundaryLine Feature Types.
