Description:
Abstract:
The North Carolina Department of Environment and Natural Resources, Division of Water Quality, in cooperation with the NC Center for Geographic Information and Analysis, developed the GIS data set, Ambient Water Quality Monitoring Sites data to enhance planning, siting, and impact analysis in areas directly affecting water quality. This file identifies locations in North Carolina where water quality data are collected on a routine basis and analyzed for presence of various chemicals.
Purpose:
This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

>Revisions and updates to this layer include:
>3.)  filename: awqms900  The September 30 2000 update consisted of
>CGIA receiving from DWQ an EXCEL spreadsheet that listed active
>ambient water quality monitoring stations. This database contained
>corrections to many of the sites from the original database.
>Additionally, many stations were moved, discontinued, or added since
>the original database.  NC Division of Water Quality has changed the
>process by which station locations are mapped. With the submission
>of this new data the layer is longer considered unverified.
>2.) filename: uvawqms1298  The December 1998 update to this layer
>consisted of projecting the data from NAD27 datum, State Plane
>projection, units of measure feet TO: NAD83 DATUM, State Plane
>PROJECTION, UNITS OF MEASURE METERS.  This was
>done to comply with the NC Geographic Information Coordinating Council's
>"Statement of Direction for North Carolina Corporate Geographic Database
>Horizontal Reference, Datum and Unit of Measure".  This reprojecting was
>done in various ways depending on the data type and content.  Vector
>data was projected using the 'project' command in ESRI's Arc software
>and topology was cleaned and built based on coverage needs.  Raster
>data was projected using ESRI's Grid module and various steps as
>applicable.
>1.) uvawqms794 - This July 11, 1994 version represents the original
>version of this data.  There was a file from March of 1991 which
>contained a point improperly placed. This 7/11/94 version corrected
>that location and the old version was deleted.  This file is
>considered unverified (UV).

Attribute_Accuracy:
Attribute_Accuracy_Report:
The attributes contained in this data were supplied by the source agency as part of the digital file from their database. Data represents information as supplied. No additional background checks were performed.
Logical_Consistency_Report:
Using ESRI's ARC/INFO GIS software, the dataset was built for point topology using the "build" command. The data set was then cleaned using the "clean" command. Topology has not been edited since the last build or clean.
Completeness_Report:
This data represents information as supplied from an internal SQL database located at DWQ.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The Ambient Monitoring Sites were manually mapped on 24k USGS paper topographic maps which meet National Map Accuracy Standards, using a best estimate with reference to surrounding features.  Latitudes and longitudes were generated using a grid overlay and entered into an internal SQL database.  DWQ then converted the data from to an EXCEL spreadsheet for conversion to a GIS coverage.  Points were checked for accuracy against NC Corportae GIS Data layers.  Refinement of the georeferencing occurred through the use of "Terrain Navigator" software which generates latitude and longitude values at the location of the cursor.

Process_Description:
NC DENR-DWQ,WQS collected the monitoring sites data and locations in an internal SQL database. The point locations were interpreted from USGS 1:24,000-scale topographic quadrangles using a grid overlay. The point locations and attribute data in this file was exported into an EXCEL spreadsheet and transferred to CGIA via e-mail for conversion to an ARC/INFO coverage for use with GIS software.
