The number of items in the ordered sequence.
A numeric position within a base sequence that represents the start of the subsequence.
A class representing numeric parameters explicitly as objects (versus representing them as datatype properties). These parameters can be inserted into containers and sequenced. This enables reuse of the same parameter value in multiple sequences.
Well-Known Text geographic representation
The WKT string representation of a location. Well-known text (WKT) is a text markup language for representing vector geometry objects on a map, spatial reference systems of spatial objects and transformations between spatial reference systems. WKT is a standards-based representation stored as an alternative to the explicit polygon boundary representation employed in the Ontology (see gen:PolygonBoundary).
A subclass of NumericParameter representing parameters with interger values.
A boolean property that specifies whether or not the starting point of the time interval is closed (inclusive of the point).
The radius of a circular region. Note: Unfortunately, the units are currently dependent the type of circular region defined. This needs to be improved.
An ordered sequence of point locations where the last point connects back to the first point, closing the polygon.
Links a subsequence to its base sequence.
Links a sequence to the first item being sequenced.
Links an item in a sequence to the subsequent item in the sequence.
A two-dimensional region defined by a polygonal boundary.
A place defined by a point or a contiguous geographic region.
A two-dimensional region defined by a geographic centerpoint and radius.
Represents a subsequence of existing base sequence. The subsequence does not replicate the items of the sequence, but merely points to the start and end positions within the base sequence.
Links a sequence to the last item being sequenced.
The ending time of a defined time interval.
The starting time of a defined time interval.
Links a polygonal region to its boundary representation.
A time interval with starting and ending time points. Intervals can be open (including the end points) or closed including the end points) or mixed including one but not the other end point).
A subclass of NumericParameter representing parameters with floating-point values.
A boolean property that specifies whether or not the endpoint of the time interval is closes (inclusive of the point).
Links a sequence to each of the items being sequenced.
A numeric position within a base sequence that represents the end of the subsequence.
Specifies the length dimension of a polygonal volume.
A class representing a demarcated region on or above the surface of the Earth.
A three-dimensional volume defined by a two-dimensional polygon plus a length component that stretches the polygon along an axis perpendicular to the polygon surface.
Indicates the ordered position of this item within the sequence, where 1 signifies the first position in the sequence.
Links to the center point of the 2-D circular region.
A location in three-space defined by a latitude, longitude, and altitude.
