Classes and construction functions for objects from the OGC Observations and Measurements specification.

Usage

OmObservation(samplingTime, procedure, observedProperty, featureOfInterest, result, metadata = NA, resultTime = NULL, resultQuality = NA, parameter = NA)
OmObservationProperty(href = as.character(NA), obs = NULL)

Arguments

samplingTime

See slot description.

procedure

See slot description.

observedProperty

See slot description.

featureOfInterest

See slot description.

result

See slot description.

metadata

See slot description.

resultTime

See slot description.

resultQuality

See slot description.

parameter

See slot description.

href

See slot description.

obs

See slot description.

Value

• The construction functions return an object of the respective class.

# TBD examples for construction methods
OmObservationProperty(href = "http://link.to/myObservation")

# get result from an observation
result <- observation@result

# the accessor method also works with lists of observations
result <- sosResult(observation)
resultList <- sosResult(observationList)
