FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION

TITLE: CRITICAL BEACH EROSION IN FLORIDA - 2010 

Geodataset Name:       CRITBEACH_JUN10
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polyline
Feature Count:         194
GENERAL DESCRIPTION:
This dataset provides an inventory of Florida's erosion problem areas fronting on the Atlantic Ocean, Straits of Florida, Gulf of Mexico, and the roughly seventy coastal barrier tidal inlets. The erosion problem areas are classified as either critical or noncritical and is based on the Critical Erosion Report for 2010. Indicates the condition of shoreline, determined by our staff of Coastal Engineers. This report is used to document areas of change and to help the beach management staff with prioritizing projects and resources to the areas of greatest need. This is an update to the critbeach_jun09.shp layer.

Local or common name of the feature.
















COUNTY

County where the feature is located.
















DESCRIPT

FGDL added field based on STATUS.
















FGDLAQDATE

The date FGDL acquired the data from the source.
















AUTOID

Unique ID added by GeoPlan
















SHAPE.LEN

USER NOTES:








This data is provided 'as is'. GeoPlan relied on the integrity
of the original data layer's topology













Lines were drawn to be offshore from the shoreline in our photos. They may not align 
with other data sources. Since the  shapefile is to be used only as a graphic, we did 
not require any survey quality accuracy. This is the final version for the year 2010.













GeoPlan relied on the integrity of the attribute information within
the original data.













Critically eroded area is a segment of the shoreline where natural processes 
or human activity have caused or contributed to erosion and recession of 
the beach or dune system to such a degree that upland development, 
recreational interests, wildlife habitat, or important cultural resources are 
threatened or lost. Critically eroded areas may also include peripheral segments
or gaps between identified critically eroded areas which, although they may be 
stable or slightly erosional now, their inclusion is necessary for continuity of 
management of the coastal system or for the design integrity of adjacent beach 
management projects.















To show the areas and severity of beach erosion as determined by our engineering staff.

The Florida Geographic Data Library is a collection of Geospatial Data

who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY: 








Determination of location and status of eroded areas in Florida.
Process Date: October 2009 to May 2010


Creation of shapefile
Process Date: 20100601


Added a new layer. Replaces DEP.COASTAL_CRIT_EROSION_AREAS08 in DataCatalog, DataMiner and MapDirect.
Process Date: 20090803


Dataset copied from previous year.
Process Date: 20100520


Updated layer inserted in ArcSDE. Metadata updated.
Process Date: 20101018


GeoPlan downloaded this dataset from the Florida Department of Environmental 
Protection's GeoData Directory website (http://www.dep.state.fl.us/gis/datadir.htm) 
in May 2011. The data was downloaded in shapefile format and was in the following 
projection: Albers NAD 83 HARN. During the AQ/QC process the following tasks were
undertaken:
- Redefined the dataset's projection from FDEP Albers to FGDL Albers.
- Upcased all records in the table.
- A DESCRIPT field was added based on STATUS.
- A FGDLAQDATE field was added based on date downloaded from its source.
- Renamed file from COASTAL_CRIT_EROSION_AREAS to critbeach_jun10
Process Date: 20110504
