Class <<FeatureType>> BoreholeCollar

A Borehole Collar is a feature corresponding to the start point of a borehole.
These are often plotted on a map. If a text descripiton of the location is available, which should be placed in the gml:description for that feature.
If no GM_Point is available, URN:CGI:unknown should be used
Implementers delivering 3-D collar locations should provide and elevation to improve interoperability.

location GM_Point 1..1 BoreholeCollar The location of the BoreholeCollar
Attribute tagged values
Tag Value
sequenceNumber 2
elevation DirectPosition 1..1 BoreholeCollar Compromise approach to supply elevation explictly for location; this is to allow for software that cannot process 3-D GM_Point. Use null if elevation is unknown. Direct position shall have a dimension of 1, and CRS will be a "vertical" CRS (e.g. EPSG CRSs in the range 5600-5799).
