Borehole must identify a BoreCollar that must be used as the reference location. The reference BoreCollar shall have a collarElevationType equal to http ”• • – ww.opengis.ne —• req { gwml2 ~ constructi ˜ ™{ construction ~ origin ~ elevation . Note that this BoreCollar need not be a physical feature, but would normally coincide with one. In a typical instance, we would find 2 or more collars, one or more real physical features, and another one as the reference collar that might or might not match one of the physical collars. { | eq { } wml2 ~ constructi ˜ ™{ construction ~ origin ~ elevation Eac š “ orehol ‡ ƒ „ A … … š ˆ › e one bhol ‡ „ eadworks Š “ oreCollar:collarElevati ‘ ‰ œ  ž ‡ Ÿ xlink:href “http: Š Š www.opengis.net Š r ‡  Š gwml Ž constructi ‘ ‰ Š construction  origin  elevation The Borehole shape SHALL be a 3D geometry that represents the complete well that includes any construction elements above the ground. 98 Copyright © 2016 Open Geospatial Consortium ¡ ¢ eq ¡ £ wml2 ¤ constructi ¥¦ ¡ borehole ¤ shape § orehole:s ¨ © ª « ¬ ­ A ® ® ¯ « © ° ± geometry that represents the complete borehole that includes any Construction Component above the ground.
