The GeoSciML Borehole package contains model elements for representing Boreholes. This is primarily through re-use of standard components from the (external) Observations and Measurements package. v2.0.1 - all links to elements in GMD namespace 'by reference' v2.0.2 - inserted XML declaration Schematron constraints for "Borehole" shape must contain either Curve or nothing (and carry an xlink:href instead) 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. The location of the 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). The hole that has this collar for its start point A special kind of Mapped Feature whose shape is 1-D (a curve) The following properties inherited from parent classes are overridden in Schematron assertions: association: shape A borehole is the generalized term for any narrow shaft drilled in the ground, either vertically or horizontally. One end of the GM_Curve that defines the shape Usually the point at a surface where drilling started. Specifies the Borehole details Links to 1-D MappedFeature instances that are logged (interpreted) intervals within a borehole. This requirement is common in geoscience boreholes Borehole specific index (or metadata) information CI_ResponsibleParty Organisation responsible for commissioning the borehole (as opposed to drilling the borehole) CI_ResponsibleParty The organisation responsible for drilling the borehole (as opposed to commissioning the borehole) The date on which drilling of the borehole commenced Indicates the drilling method used. Appropriate terms would include Rotary; Shell & Auger; Downhole Air Hammer; Hand Auger etc Indicates the position relative to ground surface where the borehole commenced. Appropriate terms would include Drilled from Ground Surface; Drilled Underground; Drilled from Quarry Floor etc The starting diameter Indicates the inclination of the borehole. Appropriate terms would include vertical; inclined up; inclined down, horizontal Interval(s) within the borehole from which core was recovered Use GM_Envelope with 1-D CRS corresponding to borehole curve shape CI_ResponsibleParty Organisation that is custodian of the core recovered from the borehole drilling started from a natural topographic surface Drilling started from the wall of an open pit or quarry Drilling started from an underground location, such as a driveway, chamber or open-stope New drill hole spudded off the wall of an existing hole http://en.wikipedia.org/wiki/Drilling_rig#Auger_drilling http://en.wikipedia.org/wiki/Drilling_rig#Air_core_drilling http://en.wikipedia.org/wiki/Drilling_rig#Cable_tool_drilling http://en.wikipedia.org/wiki/Drilling_rig#Diamond_core_drilling http://en.wikipedia.org/wiki/Drilling_rig#Direct_Push_Rigs http://en.wikipedia.org/wiki/Drilling_rig#Hydraulic-rotary_drilling http://en.wikipedia.org/wiki/Drilling_rig#Percussion_rotary_air_blast_drilling http://en.wikipedia.org/wiki/Drilling_rig#Reverse_circulation http://en.wikipedia.org/wiki/Drilling_rig#Sonic_%28Vibratory%29_Drilling
