Schema documentation for component diggs:electrodeSpacing

<element name="electrodeSpacing" type="diggs:LengthMeasureType"> <annotation> <documentation>The separation between adjacent electrodes, for arrays in which that separation is uniform: the "a" dimension of a Wenner array, and the probe spacing of a Wenner probe applied to a concrete surface.</documentation> </annotation> </element>

The full separation between the two current electrodes, for arrays in which the current and potential pairs are separated differently, principally Schlumberger. It is not the half-separation against which sounding curves are conventionally plotted.

The full separation between the two potential electrodes, for arrays in which the current and potential pairs are separated differently, principally Schlumberger. It follows the same convention as diggs:ResistivityReadingType/currentElectrodeSeparation.

The length of the current dipole of a dipole-dipole array: the separation between the two current electrodes, which equals the separation between the two potential electrodes (the "a" spacing in the n-a dipole-dipole notation).

<element name="dipoleLength" type="diggs:LengthMeasureType"> <annotation> <documentation>The length of the current dipole of a dipole-dipole array: the separation between the two current electrodes, which equals the separation between the two potential electrodes (the "a" spacing in the n-a dipole-dipole notation).</documentation> </annotation> </element>

The separation between the current dipole and the potential dipole of a dipole-dipole array, as a multiple of diggs:ResistivityReadingType/dipoleLength (the "n" in the n-a notation) rather than as a length. The multiplier is what a survey steps from one reading to the next at a fixed dipole length.

<element name="nFactor" type="double"> <annotation> <documentation>The separation between the current dipole and the potential dipole of a dipole-dipole array, as a multiple of diggs:ResistivityReadingType/dipoleLength (the "n" in the n-a notation) rather than as a length.

The bearing of the line along which the electrode array was laid out, for surveys in which orientation is varied or otherwise significant. An array line has no direction, so give the one of its two opposed bearings that falls between 0 and 180 degrees. The reference direction is carried by the refAzimuth attribute of the measure.

The position of the array for this reading, normally its center. Give it where readings were taken at different positions, principally constant separation traversing and successive points on a structure. Where every reading shares one position, the sampling feature the test was performed at carries it.

<element minOccurs="1" name="measuredResistance" type="diggs:ElectricResistanceMeasureType"> <annotation> <documentation>The resistance read from the instrument for this reading.</documentation> </annotation> </element>

The apparent resistivity computed from the measured resistance and the array geometry. It is the resistivity of an equivalent homogeneous medium; where the ground is layered or anisotropic it is not the resistivity of any one layer.

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.

The three forms are never combined on one reading - a Wenner array's single uniform spacing, a Schlumberger array's independently stated current and potential pair separations, and a dipole-dipole array's dipole length and separation multiplier describe the same underlying idea (how far apart the electrodes are) in three shapes that do not share a common representation, which is why this is a choice rather than three independently optional siblings.</documentation>
