The 'Geospatial Attributes of Gages for Evaluating Streamflow, version II'
(GAGESII)
provides geospatial data and classifications for 9,322 stream gages maintained by the U.S. Geological Survey (USGS). findGAGESII
returns a SpatialPointsDataFrame*
of GAGESII outlets within an AOI. Data comes from the USGS CIDA server and contains the following attributes:
'id' : character
Internal feature number
'STAID' : character
USGS NWIS Station ID
'STANAME': character
USGS NWIS Station Name
'CLASS' : character
Classification (Ref or Non-ref)
'AGGECOREGION' : numeric
Aggregated ecoregion
'DRAIN_SQKM' : numeric
Drainage area, sq km
'HUC02' : numeric
Hydrologic Unit Code, 2-digit
'LAT_GAGE' : character
'LNG_GAGE' : character
Longitude, decimal degrees
'STATE': character
State at gage location
'HCDN_2009' : character
If gage is part of HCDN-2009
'ACTIVE09' : numeric
If gage active in water year 2009
'FLYRS1990' : numeric
Number of complete years of flow data between 1900 and 2009
'FLYRS1950' : numeric
Number of complete years of flow data between 1950 and 2009
'FLYRS1990' : numeric
Number of complete years of flow data between 1990 and 2009
If basins = TRUE
a SpatialPolygonsDataFrame
of the gage drainage basin will also be appended
to the returned list and contain the following attributes:
'id' : character
Internal feature number and data identifier
'ogr_fid' : character
Internal feature number
'area': character
Basin Area
'perimeter' : character
Basein Parameters
'gage_id' : numeric
USGS NWIS Station ID
