Generalized USGS Water Meta Data API retrieval function
Source:R/read_waterdata_metadata.R
read_waterdata_metadata.RdFunction to get metadata from Water Data API. These are useful to get the human readable words and other metadata associated with USGS codes.
Arguments
- collection
character, can be any existing collection such as "parameter-codes", "agency-codes", "altitude-datums", "aquifer-codes", "aquifer-types", "coordinate-accuracy-codes", "coordinate-datum-codes", "coordinate-method-codes", "hydrologic-unit-codes", "medium-codes", "national-aquifer-codes", "reliability-codes", "site-types", "statistic-codes", "topographic-codes", "time-zone-codes".
- max_results
The optional maximum number of rows to return. This value must be less than the requested limit.
- limit
The optional limit parameter is used to control the subset of the selected features that should be returned in each page. The maximum allowable limit is 10000. It may be beneficial to set this number lower if your internet connection is spotty. The default (
NA) will set the limit to the maximum allowable limit for the service.
