This statewide point datalayer represents active and
discontinued stations at which USGS collects or had previously
collected streamflow data.
(ESRI Shapefile with ArcGIS .lyr and ArcView 3x .avl)
ManuscriptData-collection station locations and attributes were derived from the National Water Information System data base of the USGS.
MethodologyUSGS staff created an ascii file of latitude, longitude and attribute data pulled from the data base. This file was then used to generate a point coverage. The coordinates were originally measured from USGS 1:25,000 and 1:24,000 topographic quadrangles with an accuracy to one second.
AttributesThis data layer has a .PAT with the following items:
|STATION#||data-collection station identifier|
|LONG||longitude of station|
|LAT||latitude of station|
|TYPE||type of data-collection station, where streamflow records are or have been collected:|
|1 = streamflow-gaging station where continuous
streamflow records are or have been collected
2 = peak-flow partial-record station
3 = low-flow partial-record or miscellaneous-measurement station
4 = peak- and low-flow partial-record station
MaintenanceMassGIS is maintaining this datalayer. Updates will be made as information is made available from USGS.
