Classes and creation functions for Sampling Features

Sampling Feature classes.

SamsShape represents the geometry of a spatial sampling feature, that can be used as a feature of interest. Currently, only points are supported.

Objects from the Class

Objects can be created by calls to the creation functions:

SamsSamplingFeature(...)

SamsShape(...)

Slots

identifier:

Object of class "character" ~~

name:

Object of class "character" ~~

type:

Object of class "character" ~~

sampledFeature:

Object of class "character" ~~

shape:

Object of class "SamsShape" ~~

id:

Object of class "character" ~~

point:

Object of class "GmlPoint" ~~

id:

Object of class "character" ~~

srsName:

Object of class "character" ~~

srsDimension:

Object of class "integer" ~~

axisLabels:

Object of class "character" ~~

uomLabels:

Object of class "character" ~~

Extends

SamsShape extends "GmlGeometry", directly.

SamsSamplingFeature extends "GmlFeature", directly. SamsSamplingFeature extends "GmlFeatureOrNULL", by class "GmlFeature", distance 2. SamsSamplingFeature extends "GmlFeatureOrGmlFeaturePropertyOrNULL", by class "GmlFeature", distance 2.

Methods

sosCoordinates

signature(obj = "SamsSamplingFeature"): access to the coordinates of the feature.

sosFeatureIds

signature(obj = "SamsSamplingFeature"): access to the identifier of the feature.

sosFeaturesOfInterest

signature(obj = "SamsSamplingFeature"): access the feature itself.

sosName

signature(obj = "SamsSamplingFeature"): access a human-readable name of the feature.
