How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    The stream gaging station attributes were used as supplied from the USGS and not significantly checked for accuracy.

  2. How accurate are the geographic locations?

    Positions of the gaging stations were given in latitude and longitude coordinates by the source agency, and used without edits. Contact the USGS for details on the station sources.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This file represents all USGS stream-gaging stations within the Tar-Pamlico River Basin. This data is considered unverified. This data set was developed with the best resources available at the time of its creation.

  5. How consistent are the relationships among the observations, including topology?

    Using ESRI's ARC/INFO GIS software, the dataset was built for point topology using the "build" command. Topology has not been edited since the last build or clean.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?

Access_Constraints: None
