Frequently-asked questions:

What does this data set describe?
Title:
GISDATA.SAVEM_benthic

Abstract:
All active and proposed benthic water quality sample sites for the Southern Appalachian Volunteer Environmental Monitoring (SAVEM) project.

Supplemental information:
Merged version of all SAVEM Save Our Stream sample sites.
Points digitized by Andy Brown and Equinox Environmental in original customer input shapefiles.  NBII SAIN GIS group made modifications such as deleting, adding, and moving points, adding ID field, and merging all points together.
Bugs were collected in the soil at the bottom of a stream.

  5. What is the general form of this data set?

    Geospatial data presentation form: vector digital data

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):
      • Entity point (57)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. 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.

      Vertical coordinate system definition:
      Altitude system definition:
      Altitude resolution: 1.000000
      Altitude encoding method: Explicit elevation coordinate included with horizontal coordinates

How reliable are the data; what problems remain in the data set?
  1. How well have the observations been checked?

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

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

    Points digitized by Andy Brown in original customer input files proposed sos sample stations.shp, and active sos sample stations.shp.  Multiple parent files were merged by NBII SAIN GIS group into with modifications such as deleting, adding, and moving points.  And ID field was added by NBII SAIN GIS group.

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