The package has five data download functions: GetServices(): show all public
HydroServers from the HIS Central Catalog.
HISCentral_GetSites() and HISCentral_GetSeriesCatalog(): search for sites or time series
from the HIS Central catalog based on geographic bounding box, server, or keyword.
GetVariables(): Show a data.frame with all variables on the server.
GetSites(): Show a data.frame with all sites on the server.
GetSiteInfo(): Show what variables, methods and quality control levels are
available at the specific site. GetValues(): Given a site code, variable code, start time
and endtime, fetch a data.frame of all the observation time series data values.
The data.frame has two columns: time and DataValue. This function has an optional "daily"
parameter, you can set daily="max", daily="min" or daily="mean" to get aggregated daily
values. The GetValues function can also retrieve WaterML 1 or WaterML 2.0 data
from a custom URL. The package also has five data upload functions:
AddSites(), AddVariables(), AddMethods(), AddSources(), and AddValues().
These functions can be used for uploading data to a HydroServer Lite ODM database
via the JSON data upload web service interface.
