Notes:A SpatialEntity is part of a soil description.
It provides a link between a notional feature (description package) and one spatial representation of it, or part of it. (Sites, Transects, Exposures, Surface Traces and Intercepts, etc)
* the specific bounded occurrence, such as a map polygon
* the SpatialEntity carries a geometry or shape
- the association with a Soil or Landscape Feature provides the specification of all the other descriptors
- the association with a Sampling Feature provides the context and dimensionality

A SpatialEntity is always associated with some sampling feature - e.g. a Soil Sample, a Landscape, a Soil Layer etc.

<<voidable>>observationMethodSpatialObservationMethodTerm1...-1SpatialEntity observationMethod is a metadata snippet indicating how the spatial extent of the mapped feature was determined. ObservationMethod is a convenience property that provides a quick and dirty approach to observation metadata when data are reported using a feature view (as opposed to observation view). This property corresponds (loosely) to ISO19115 Lineage. (eg: digitised, Global Positioning System, published map, field observation, aerial photography, field survey

<<voidable>>positionalAccuracyDQ_PositionalAccuracy1...1Quantitative values define the radius of an uncertainty buffer around a mappedFeature (eg: a positionAccuracy of 100 m for a line feature defines a buffer polygon of total width 200 m centred on the line). Corresponds to ISO19115 DQ_PositionalAccuracy.
