- Abstract
- This datalayer is a point coverage representing United States Geological Survey (USGS) realtime streamflow sampling station locations in the United States and territories. This layer contains geographic and attribute data for 7,055 stations with streamflow measurements recorded for a single date between July 7, 2003 and August 4, 2003. Attribute data also includes a URL for each station that provides a direct link to the most recent streamflow data available from the USGS water resources Web site. Historical data is also available from the USGS water resources Web site. The datalayer was published as part of the USGS Global GIS : global coverage database. Sampling stations are equipped with telemetry to transmit data on streamflow, temperature, and other parameters back to a database for real-time viewing via the World Wide Web. A map of the realtime stations is produced every day and is available from the USGS Web site: http://waterdata.usgs.gov/nwis/.
- Purpose
- This map layer was created to show the locations of the stream gage sampling network. The locations are used to enable links to station Web pages that provide the latest observational data using an internet map server. This layer is intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production. This layer will provide a basemap for layers related to socio-economic and political analysis, statistical enumeration and analysis, or to support graphical overlays and analysis with other spatial data. More advanced user applications may focus on demographics, urban and rural land use planning and related areas including defining boundaries, managing assets and facilities, integrating attribute databases with geographic features, spatial analysis, and presentation output.

- Data Quality Information
- Logical Consistency Report
- All locations are points.
- Completeness Report
- 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.
- Horizontal Positional Accuracy Report
- 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.

- Hydrologic Unit Code of the station. The United States is divided and sub-divided into successively smaller hydrologic units which are classified into four levels: regions, sub-regions, accounting units, and cataloging units. The hydrologic units are arranged within each other, from the smallest (cataloging units) to the largest (regions). Each hydrologic unit is identified by a unique hydrologic unit code (HUC) consisting of two to eight digits based on the four levels of classification in the hydrologic unit system.
