This section describes the three features available in OS OpenMap – Local. 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.
Values are given here to indicate the maximum length that you will find in the data, to aid in developing applications. Length is not constrained in the GML (Geography Markup Language).
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory, and it may have multiple occurrences. For example:
‘1’ – there must be a value.
‘2’ – there must be two values.
‘n’ – there may be one or more values.
‘0’ – population is optional.
These values may be used in combination.
An association identifies the relationship between features. The relationships are by reference only and the value will be the identifier of the referenced feature.
Not all features available in the product are included in the raster format. For a full list of features and their styling in the raster format, please refer to the product's legend, which is available online via the OS OpenMap – Local Product Support page on the OS websiteort).
A road is defined as a metalled way for vehicles. A vehicle is defined as one with wheels on both sides of its body. Metalling is defined as any artificial (man-made) surface including areas of asphalt, concrete and gravel. Roads that form part of the public network and driveways to private properties that are over 100m in length are captured. Dual carriageways are represented by centrelines when the two carriageways are closer than 32.5m, roundabouts are represented by points when smaller than 450m², dead ends are removed when shorter than 36m, and roads are simplified with a 4m tolerance.
