# Site Data Import from Water Quality Portal Returns a list of sites from the Water Quality Portal web service. This function gets the data from: [https://www.waterqualitydata.us](https://www.waterqualitydata.us). Arguments to the function should be based on [https://www.waterqualitydata.us/webservices_documentation](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. ```r whatWQPsamples(..., convertType = TRUE, legacy = TRUE) whatWQPmetrics(..., convertType = TRUE) whatWQPsites(..., legacy = TRUE, convertType = TRUE) ``` ## Arguments - ``...``: see [https://www.waterqualitydata.us/webservices_documentation](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](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, 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. - `legacy`: Logical. If TRUE, uses legacy WQP services. Default is TRUE. Setting legacy = FALSE uses WQX3.0 WQP services, which are in-development, use with caution. ## Returns A data frame with information on the sampling activity available from the Water Quality Portal for the query parameters. data frame that includes information on site metadata. ## Examples ```r site1 <- whatWQPsamples(siteid = "USGS-01594440") type <- "Stream" sites <- whatWQPsamples(countycode = "US:55:025", siteType = type) lakeSites_samples <- whatWQPsamples(siteType = "Lake, Reservoir, Impoundment", countycode = "US:55:025") type <- "Stream" sites <- whatWQPmetrics(countycode = "US:55:025", siteType = type) lakeSites_metrics <- whatWQPmetrics(siteType = "Lake, Reservoir, Impoundment", countycode = "US:55:025") site1 <- whatWQPsites(siteid = "USGS-01594440") type <- "Stream" sites <- whatWQPsites( countycode = "US:55:025", characteristicName = "Phosphorus", siteType = type ) ``` ## See Also whatWQPdata readWQPsummary whatNWISdata
