Returns a POINT feature class of active, stream network, NWIS gages for an Area of Interest. If a POINT feature is used as an AOI, then the returned sites within the requested buffer, are sorted by distance (in meters) from that POINT.
sf (MULTI)POINT or (MULTI)POLYGON. An 'area of interest' can be provided as either a location (sf POINT) or area (sf POLYGON) in any Spatial Reference System.
character (PROJ string or EPSG code) or numeric (EPSG code). A user specified - target -Spatial Reference System (SRS/CRS) for returned objects. Will default to the CRS of the input AOI if provided, and to 4326 for ID requests.
numeric. The amount (in meters) to buffer a POINT AOI by for an extended search. Default = 20,000. Returned results are arrange by distance from POINT AOI
The returned object(s) will have the same
Spatial Reference System (SRS) as the input AOI. If a individual or set of
IDs are used to query, then the default geoserver CRS of EPSG:4326 is
preserved. In all cases, a user-defined SRS can be passed to
which will override all previous SRS's (either input or default).
All buffer and distance operations are handled internally using in
EPSG:5070 Albers Equal Area projection
