Implementation of ISO 19148:2021 §6.3 Linear Element concept for DIGGS.
A LinearExtent defines a location as a linear extent or interval, with the first
vertex representing the starting location and the last vertex representing the end
location. This is the fundamental spatial object along which linear referencing V
measurements are made. For DIGGS applications, LinearExtent typically represents: -
Borehole centerline (3D path from collar to bottom) - Well trajectory (including
deviated wells) - CPT sounding path - Geophysical trackline - Survey transect or
traverse The geometry is stored in gml:posList with coordinates in the order they
are traversed during measurement. Measurements proceed from first to last
coordinate.

QName Type Use Annotation
axisLabels gml:NCNameList optional
gml:id ID optional 
Database handle for the object. It is of XML type ID, so is constrained to be
unique in the XML document within which it occurs. An external identifier for the object in
the form of a URI may be constructed using standard XML and XPointer methods. This is done
by concatenating the URI for the document, a fragment separator, and the value of the id
attribute.
srsDimension positiveInteger optional
srsName anyURI optional
uomLabels gml:NCNameList optional
