Edge LineString 2 A spatial lineString locating the landward 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. The default CRS is a 3D CRS to EPSG 7405 with confirmed type, European reference frame and UK OS transformation with geoCOBie Unit of 'LineString:EPSG7405:ETRS89:OSTN15:OSGM15' | Geometry Units: LineString:EPSG7405:ETRS89:OSTN15:OSGM15 | EA2 | P09 Operations | No | Component.Attribute.Name.EdgeLineString2 | 18-04-2024 |
