Description

Base class of a connection to a Sensor Observation Service.

Usage

SOS(url, method = SosDefaultConnectionMethod(), version = "1.0.0", parsers = SosParsingFunctions(), encoders = SosEncodingFunctions(), dataFieldConverters = SosDataFieldConvertingFunctions(), curlOptions = list(), curlHandle = getCurlHandle(), timeFormat = sosDefaultTimeFormat, verboseOutput = FALSE, switchCoordinates = FALSE, ...)
# accessor methods ...

Additional parameters that are passed on to the getObservation call that is done within this function.

Value

  • The construction functions returns an object of class SOS-class.

Objects from the Class

Objects can be created by calls to the construction function of the form SOS(...).

Object from the class can be used in calls to function for metadata retrieval of sensors (link{describeSensor-methods}) and observation data queries (link{getObservation-methods} and link{getObservationById-methods})

Details

From the introduction of the specification document: The goal of SOS is to provide access to observations from sensors and sensor systems in a standard way that is consistent for all sensor systems including remote, in-situ, fixed and mobile sensors.
