Attributes
An attribute is a particular piece of data that describes a property of an object. Each Element Type is described by a different set of attributes, although there are some attributes that are common to many Element Types.
The table below lists the attributes that are applicable to this Element Type, along with the data profile requirements for each attribute and details of when and how each should be used and delivered.

Edge LineString 1 A spatial lineString locating the exposed edge or spatial feature of an element further classified by the associated LineStringType attribute. Edge lineStrings may be singular (Edge LineString1) required in all cases, or paired (Edge LineString 1 and 2); the second may not be required indicated by 'n/a'. A lineString is a series of design or measured spatial triple points (easting, northing, elevation) each connected by a single non-crossing line, with single points at each end, that locate an element. A lineString is expressed as a JSON array of type geoJSON lineString, e.g. [[x1,y1,z1],[x2,y2,z2],...] It is further classified by the associated LineStringType attribute confirming its relative location to the element. Interim points should be spaced at a maximum of 2m for lines < 10m in length, or 10m otherwise.
