Classes of the Namespace sa

Description

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

Usage

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

Arguments

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

Value

Construction functions: An object of the respective class.

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.
