TITLE: SAND SOURCES FOR THE STATE OF FLORIDA

Geodataset Name:      FLSAND
Geodataset Type:      SHAPE
Geodataset Feature:   POINT
 

GENERAL DESCRIPTION:

This dataset contains data on sand sources for the State of Florida.  
This data represents a combination of several sediment texture 
datasets offshore. Sediment grain size, percent composition of mud, 
sand, and clay and water depth are described at each sampling location.

USER NOTES:

The purpose of these data is to assist coastal managers in the location of
compatible sand resources for beach nourishment in order to facilitate the project
planning process. 
These data are based on interpretation of available information and should
not be construed as legally binding.
 

FGDL QUALITY ASSURANCE STATUS:

-Reprojected data to FGDL Albers HPGN (See "Map Projection Parameters" below)
-Extent set to the State of Florida
-Upcased all character records
-Dropped old internal coverage items: AREA, PERIMETER, SE_SAND_, SE_SAND_ID

DATA LINEAGE SUMMARY:

This data was downloaded by the FGDL in 2002 from Ocean Planning and Governance
Geographic Information System (Ocean GIS) webpage at: 
http://www.csc.noaa.gov/opis/html/data.htm 
The data was clipped to the State of Florida and then projected to FGDL Albers HPGN.
When received, data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980,
Units: Decimal degrees.
The dataset's prior history from OPIS is as follows:
These data were acquired from the Florida Geological Survey (FGS), and the U.S.
Geological Survey (USGS). Attribute data provided by the FGS and USGS were compiled and joined to
an ARC/INFOĢ coverage for the coasts of Florida and Georgia that had been
generated by the NOAA Coastal Services Center using the latitudinal and longitudinal
sampling station coordinates. Two additional ARC/INFOĢ coverages for the
west-central coast of Florida were reprojeted and appended. The attributes were
simplified. Finally, the South Carolina Department of Natural Resources provided
data in the form of an ARC/INFOĢ coverage. In order to append these files,
attributes were simplified.
