This section describes the three features available in the OS VectorMap District product. The attributes associated with these feature types are listed below along with a brief description of their data properties.
The name of the attribute and what it is describing.
The nature of the attribute, for example a numeric value or a code list value.
The length of the attribute provided (optional).
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory within the product. These are denoted by:
‘1’ there must be a value.
‘2’ there must be two values.
‘n’ there may be one or more values.
‘0’ population is optional.
An association identifies the relationship between features. These relationships are by reference only and the value will be the identifier of the referenced feature.
