Value

The returned output depends on the type of the input parameter

time. If time is type

c("POSIXct", "POSIXt") the returned object contains queried and interpolated water levels. If

time is type Date the returned object contains daily averaged water levels.

Details

This functions queries online water level data through the REST service of PEGELONLINE. The gauging data from PEGELONLINE have a high temporal resolution of 15 minutes, enabling meaningful linear temporal interpolation if time is supplied with type c("POSIXct", "POSIXt"). If time is supplied with type Date water level data are aggregated to daily averages.

Since data from PEGELONLINE expire after 31 days, this function is only applicable to query unvalidated water level values for the last 31 days before function call. If you need older and validated data, feel free to contact the data service at the Federal Institute of Hydrology by email (Datenstelle-M1@bafg.de).
