Classes of the Namespace sa

Classes and construction functions for elements from the OGC specification “Observations and Measurements - Part 2 - Sampling Features”.

SaSamplingPoint(sampledFeatures, position, relatedObservation = list(NA),
                relatedSamplingFeature = list(NA), surveyDetails = NA, id = NA_character_)

Arguments

sampledFeatures	~~
position	~~
relatedObservation	~~
relatedSamplingFeature	~~
surveyDetails	~~
id	~~

Objects from the Class

Objects can be created by calls to the construction functions of the form SaSamplingPoint(...).

Slots

sampledFeatures:

Object of class "list" which contains the sampled features.

position:

Object of class "GmlPointProperty" which contains the position of a feature.

relatedObservation:

Object of class "list" which contains identifiers of related observations.

relatedSamplingFeature:

Object of class "list" which contains identifiers of related sampling features.

surveyDetails:

Object of class "ANY" which can contain information about survey details (which are currently no modeled in an R class).

id:

The identifier of a sampling elements (object of class "character").

shape:

Object of class "ANY" which could be used to model the shape of a sampling surface.

area:

Object of class "ANY" which could be used to model the area of a sampling surface.

Extends

SaSamplingPoint and SaSamplingSurface: Class "GmlFeature", directly. Class "GmlFeatureOrNULL", by class "GmlFeature", distance 2.

Methods

show

signature(object = "SaSamplingPoint"): ...

show

signature(object = "SaSamplingSurface"): ...

sosCoordinates

signature(object = "SaSamplingPoint"): access to the coordinates of the feature.

sosFeatureIds

signature(object = "SaSamplingPoint"): access to the identifier of the feature.

sosFeaturesOfInterest

signature(object = "SaSamplingPoint"): access to the feature of interest, i.e. the point itself.

Value

Construction functions: An object of the respective class.
