wqpSpecials: Site Data Import from Water Quality Portal

In USGS-R/dataRetrieval: Retrieval Functions for USGS and EPA Hydrology and Water Quality Data

Site Data Import from Water Quality Portal

Description

Returns a list of sites from the Water Quality Portal web service. This function gets the data from: https://www.waterqualitydata.us. Arguments to the function should be based on https://www.waterqualitydata.us/webservices_documentation. The return from this function returns the basic metadata on WQP sites. It is generally faster than the whatWQPdata function, but does not return information on what data was collected at the site.

Usage

whatWQPsamples(..., convertType = TRUE, checkHeader = FALSE)

whatWQPmetrics(..., convertType = TRUE, checkHeader = FALSE)

whatWQPsites(..., checkHeader = FALSE)

Arguments

...	see https://www.waterqualitydata.us/webservices_documentation for a complete list of options. A list of arguments can also be supplied. One way to figure out how to construct a WQP query is to go to the "Advanced" form in the Water Quality Portal: https://www.waterqualitydata.us/#mimeType=csv&providers=NWIS&providers=STORET Use the form to discover what parameters are available. Once the query is set in the form, scroll down to the "Query URL". You will see the parameters after "https://www.waterqualitydata.us/#". For example, if you chose "Nutrient" in the Characteristic Group dropdown, you will see characteristicType=Nutrient in the Query URL. The corresponding argument for dataRetrieval is characteristicType = "Nutrient". dataRetrieval users do not need to include mimeType, zip, and providers is optional (these arguments are picked automatically).
convertType	logical, defaults to TRUE. If TRUE, the function will convert the data to dates, datetimes, numerics based on a standard algorithm. If false, everything is returned as a character.
checkHeader	logical, defaults to FALSE. If TRUE, the code will check that the curl header response for number of rows matches the actual number of rows. During transition to WQX 3.0 profiles, it's unclear if the counts will be correct.
