This is a Vector data set. It contains the following vector data types (SDTS terminology):
Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000001. Longitudes are given to the nearest 0.000001. Latitude and longitude values are specified in Decimal degrees.
The horizontal datum used is D_WGS_1984.
The ellipsoid used is WGS_1984.
The semi-major axis of the ellipsoid used is 6378137.000000.
The flattening of the ellipsoid used is 1/298.257224.
Sequential unique whole numbers that are automatically generated.

The primary purpose of this coverage is to produce an imagemap for use on the World Wide Web.
Every hour, an automatic process retrieves the realtime pages from each District and parses them to find the stations served and the URL for each station's data. The station numbers on this list are matched against a master list of USGS stations to find the station name and the latitude/longitude of each realtime station. This information is used to prepare an updated point coverage.
CLASS values for the flow are: > le 0 Not valid (internal use) > 1 New minimum > 2 ge old minimum and le 5th percentile > 3 gt 5th percentile and le 10th percentile > 4 gt 10th percentile and le 25th percentile > 5 gt 25th percentile and le 75th percentile > 6 gt 75th percentile and le 90th percentile > 7 gt 90th percentile and le old maximum > 8 New maximum

Latitudes and Longitude are specified to the nearest second. The position is determined from 1:24,000-scale maps, where available, but other lower scale (i.e. less resolution) maps may be used also.
This coverage includes only those stations with data actually being served on the WWW at the time of compilation. Some stations -- and sometimes whole states -- may be excluded because of temporary webserver or network problems. In addition, a station with data may not be shown on the map if its name and location are not yet in the master list.
All locations are points.
Are there legal restrictions on access or use of the data?
