Summary of Data Available from Water Quality Portal
Description
Returns a list of sites with year-by-year information on what data is available. The function gets the data from: https://www.waterqualitydata.us. Arguments to the function should be based on https://www.waterqualitydata.us/webservices_documentation. The information returned from this function describes the available data at the WQP sites, and some metadata on the sites themselves.
Usage
readWQPsummary(...)
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). |
