The North Carolina Department of Environment and Natural Resources, Division of Water Quality,with funding from the NC Clean Water Management Trust Fund and in cooperation with the NC Center for Geographic Information and Analysis, developed the digital fish community sampling data to enhance water quality assessment & plan review of Trust Fund project applications. This file identifies points where fish community sampling has been done.
This data was created to assist governmental agencies and others in making resource management decisions through use of a Geographic Information System (GIS).

The NC DENR-DWQ maintained the biological records in a 4D database with no geographic reference. The database includes attributes for river basin, subbasin, site description, and collection date. The data was converted to an EXCEL spreadsheet for conversion to a GIS coverage. The digital file is updated as changes occur.
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"
These data represent the locations and results of the fish community sampling conducted and documented by the NCDWQ.
The NC DENR-DWQ maintained the biological database in a 4D database. The monitoring points 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. Points were checked for accuracy against NC Corporate GIS Data layers. In 1998 "TopoScout" software was purchased. The software generates lat/longs for the location of the cursor. DWQ will continue to refine the georeferincing of the sampling sites. DWQ converted the 4D data into an EXCEL spreadsheet for conversion to a GIS coverage. NCGIA converted this dataset to a GIS coverage using ESRI's ARC/INFO software on UNIX. The digital file is updated as changes occur.
spreadsheet with monitoring locations
Creation of digital coverage, and file updates.
The NC DENR-DWQ mapped the monitoring points on 24k USGS paper topographic maps. DWQ entered the sampling data into a 4D database and geographically referenced the data by latitude and longitude. DWQ converted the data to EXCEL and supplies CGIA with updates.
CGIA coverted the spreadsheet to a shapefile using ESRI's ArcView GIS software. The shapefile was then converted to a coverage using ESRI's ARC/INFO GIS software. CGIA updates the digital file as needed.
