SamplingFeatures are feature types that are used primarily for making observations:
SamplingFeature and collections are described in samplingBase.xsd
Station (0-D)
Profile (1-D)
SurfaceOfInterest (2-D)
SolidOfInterest (3-D) are described in this schema document
In many cases the properties of interest vary within the site, so may be represented as a coverage associated with the SamplingFeature.

A "Station" is an identified position (0-D geospatial feature).
It may be revisited for various purposes, in particular to retrieve multiple specimens or make repeated or complementary observations.
The position property of the station provides the value of the position property of observations an specimens associated with the station.
By using the Station feature, this position information and any metadata associated with it may be encoded in one place, i.e. normalised, and then re-used _by reference_ on other feature instances associated with it.
Use the srsName attribute to record the elevation datum
A "Profile" is an identified 1-D spatial feature.
It may be revisited for various purposes, in particular to retrieve multiple specimens or make repeated or complementary observations.
Specialized names for Profile include Sounding, ObservationWell, FlightLine, Transect.
In addition to the constant "property" inherited from the base type, Profiles may also have properties that vary along their length.
These are encoded as discrete coverages.

A "SurfaceOfInterest" is an identified 2-D spatial feature.
It may be used for various purposes, in particular for observations of cross sections through features.
Specialized names for SurfaceOfInterest include CrossSection, Section, Flitch, Swath, Scene, MapHorizon.
In addition to the constant "property" inherited from the base type, Surfaces may also have properties that vary across their extent.
These are encoded as discrete coverages.

A "SolidOfInterest" is an identified 3-D spatial feature used in sampling.
In addition to the constant "property" inherited from the base type, Solids may also have properties that vary within their extent.
These are encoded as discrete coverages.
A "SolidOfInterest" is an identified 3-D spatial feature used in sampling.
