SHAPE                    Data attribute inherent to the ESRI shapefile format,
                         which defines the data as a point, polyline, or polygon.
   
COUNTY                   County name
          
SURGE_ELEV               The elevation of the water for that zone above mean sea  
                         level. To get the elevation of the water above the land 
                         you would need to subtract the land elevation from this 
                         number. Refer to the Hurricane Storm Tide Atlas produced 
                         by the SWFRPC for that particular county for more 
                         information
       
CATEGORY                 The storm category for that zone. Either 4 or 5

USER NOTES:

This data was developed as part of the local mitigation strategy grant. The 
Southwest Florida Regional Planning Council was contracted to do the LMS critical
facility work on Lee, Collier, Glades and Hendry Counties. Sarasota County and 
Charlotte County were done by thier own in house GIS department. 

Because the SWFRPC did not produce those 2 counties critical facilities data, we 
can not attest to the accuracy of it. While the Charlotte County data apears to be 
accurate, the Sarasota County data has some blatant errors of which they admit, as 
in points falling far out in the water. The data here was the latest available they 
had at the time.

The dataset provides location and attribute information for use in national and 
regional cartographic and network analysis applications.
A note concerning data scale:

Scale is an important factor in data usage. Certain scale datasets are not
suitable for some project, analysis, or modelling 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.

1:250000 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 analyses. 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 web pages at:

DATA LINEAGE SUMMARY:

This data was originally released by individual counties in 2001. In 2001, the 
GeoPlan Center downloaded this dataset in shapefile format from the Southwest 
Florida Regional Planning Council (http://www.swfrpc.org/maps.htm). When received, 
the data was in the following projection: State Plane East, Datum: NAD 27, Units: 
Feet.  The shapefile was then projected to FGDL Albers HPGN (See "Map Projection 
Parameters" below).
