This property should be used in preference to lithDescription to define lithology for rigid definitions that adhere to a specific classification system. Either a classificationCode property or lithDescription property must be present (or both). lithDescription should be use in conjunction with classificationCode (eg. well-graded sand for classification code = SW) to further describe the lithology or for a more extensive description in lieu of using color, particleSize, grainSizeDistribution, descriptiveProperties, and constituents property elements (eg. well-graded sand (SW), fine-grained, dark grey, massive, dry, hard).

An act ("event"), whose results are estimates of the value of a property of the investigation target, measured at a time instant or within a time interval, and within a spatial domain, typically derived from a test procedure. Describes the time that the result applies to the property of the investigation target. This is often the time of interaction by a sampling activity or measurement procedure with a real-world feature. Describes the time when the result became available, typically when the procedure associated with the observation was completed For some observations this is identical to the samplingTime. However, there are important cases where they differ. The resultTime is the time when the procedure associated with the measurement act was applied. For some measurements this is identical to samplingTime, in which case the resultTime may be omitted. Example: Where a measurement is made on a specimen in a laboratory, the samplingTime should record the time the specimen was retrieved from its host, while the resultTime should record the time the laboratory procedure was applied. Example: Where monitoring observation results are post-processed, the resultTime is the post-processing time, while the samplingTime preserves the time of initial interaction with the world. Describes the time period during which the result is intended to be used. A property that contains the information about what properties are being measured, the results of the measurement, and the associated locations that the measurement results relate to. A code or name for the property as used by the data provider. This value can come from a controlled list of terms or be an uncontrolled text string. The value would be commonly used to label a column of a log sheet or provide other local meaning to the property. The value of mnemonic should be unique for all of the properties included in the dataValue block transmitted as part of this measurement. The data type for this property (eg. double, long, string, etc.) The official name of this property as derived from a dictionary of defined terms. The codespace value must be populated and should contain the URN to allow applications to validate this value as a known property. Unit of measurement for the property.

This value defines a value to be interpreted as null for this property in the dataValues block. The reason attribute can be used to define the reason for the null value, (eg. witheld). This can be customized with an other: qualifier (eg. other:below detection limit) or reference a URI for a more complete definition. If the property should be interpreted in a particular context (eg. value is only valid for range of overburden pressures, etc.), then the context of the property is described here. Fraction of total sample analyzed (from enumerated list) A description of corrections used to obtain the reported result. Commonly used to report N-values from SPT tests, or to describe any other adjustments made to the reported data. Can come from a controlled list. The method by which the property value is obtained.

For example, if a procedure requires a collected sample to be screened such that the procedure operates on a specific size fraction of an overall soil sample, this description could be used to describe the size fraction(s) used in the prepared sample for analysis. However, if a more detailed and quantitative breakdown of size fractions is needed, the retainedSizeFraction property within the specific test procedure should be used to detail this information. Size fraction from which test portion was obtained. The weight of the specimen prior to drying The weight of the sample following drying. The shape of the specimen being tested, defined by the following controlled terms: 1) cylinder; 2) cube 3) cuboid - a square cylinder or cube with uneven sides disturbed intact specimen; 4) sphere The vertical dimension of the specimen The vertical dimension of the specimen For cylindrical specimens, a measure of the cylinder's diameter A measure of one of the cross-sectional, or horizontal, dimensions of the prepared sample. A measure of the other of the cross-sectional, or horizontal, dimensions of the prepared sample The vertical dimension of the specimen An object that describes the procedure(s) used to prepare a sample for a particular test. It can optionally reference a sample (if this preparation procedure occurs on a specific sample as part of another test procedure that uses more than one sample. The gml:description field is used to carry the description of the preparation procedure. A component of a sensor that measures one specific property (measurand), optionally along a single geometric axis The location that the detector measures (eg response zone of the detector) Contains the code value of the property being measured. Codespace must be defined and the value should occur within a dictionary Compass bearing direction (relative to true north) defining the measurement axis direction (for directional measurements, eg. component of an extensometer, accelerometer, etc.) Inclination of measurement axis (measured positively down from horizontal); used for directional measurements, eg. extensometer, accelerometer, etc. The constraint defines a condition under which the limit applies An enumeration of various parameters upon which the property result may be qualified This will typically be used to record environmental parameters, or event-specific parameters that are not tightly bound to either the earth materials for which properties are being estimated, or the procedure. Parameters that are tightly bound to the procedure should be encoded within the procedure object. Identifies the reference point location for the sensor. This may be the top of casing for a tape used to detect water level or it could be a location within the response zone itself. A controlled list that indicates the target being investigated by this feature: Deep Foundation - investigation of deep foundation elements Earthworks - earth materials excavated and/or emplaced by engineering activity Ground Water - hydrology and chemistry of ground water; Indoor Atmosphere - meteorology and chemistry of air in indoor spaces Natural Ground - earth materials sampled in natural or undisturbed state; Outdoor Atmosphere - meteorology and chemistry of air in outdoor spaces Surface Water - hydrology and chemistry of surface water; An act ("event"), whose results are estimates of the value of a property of the investigation target, measured at a time instant or within a time interval, and at a location or series of locations, derived from a test procedure. Identifies the location of the response zone within the sampling feature that is being monitored. For example, for a water level measurement, the location would be the depth interval in the well where perforations are located (or where water enters the well) A property that contains the information about what properties are being measured, the results of the measurement, and the associated locations that the measurement results relate to.

Both minimumGrainSize and maximumGrainSize may be populated to represent a sample with grain sizes between the two specified. A sampling feature that is an installation within a borehole, used for observing, withdrawing, or injecting fluids.
