FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION
VERSION 2006
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:

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/INFO 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/INFO 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/INFO coverage. In order to append these files, attributes were simplified.
