TITLE: SOUTHWEST FLORIDA WATER MANAGEMENT DISTRICT LANDS

Geodataset Name:       SWFDL
Geodataset Type:       SHAPEFILE
Geodataset Feature:    POLYGON
GENERAL DESCRIPTION:
This dataset includes Southwest Florida Water Management District land boundaries. Included are both acquired and proposed land acquisitions. It includes fee, less-than-fee and perpetual easement acquistions. It also includes areas proposed for fee or less-than-fee acquisition. This layer is an update of the SWFDL layer that was released with FGDL Version 2003.

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

A note concerning data scale:

Scale is an important factor in data usage. Certain scale 
datasetsare 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.

1:250000 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 sectionand the Data Source Contact section of 
this documentation. For more information regarding scale 
and accuracy, see our web pages at:

DATA LINEAGE SUMMARY:
FEE AND LESS-THAN-FEE ACQUISITIONS
The ground control surveys used for creating the majority 
of these data were made by the Survey section of the 
Southwest Florida Water Management District (SWFWMD).

Some surveys were completed by individual survey firms 
under contract to the seller, but had to meet the Southwest 
Florida Water Management District Survey Section's requirements.  
A Professional Surveyor verified these from the Survey section 
of the SWFWMD.

For large multi-parcel acquisition projects, such as the Green 
Swamp and Annutteliga Hammock, surveys were not obtained 
for the small tracts (most are less than 20 acres).  Sketches 
were made based on the legal descriptions.  These projects 
are located in Lake, Polk and Hernando counties.
Process Date: Unknown

ACQUIRED LANDS This layer is derived from the Parcel layer. The ArcINFO DISSOLVE command was used to eliminate internal parcel lines and leave only the exterior project boundaries. A metadata report for the Parcel layer is available from the District. Each new parcel is combined with the existing coverage and attributed within ArcEdit. Topology is created for the coverage using CLEAN or BUILD. Process Date: Unknown
PROPOSED LANDS Areas targeted for acquisition were delineated on USGS 7.5 quadrangles or paper copies of USGS color infrared (CIR) DOQQ's. Process Date: Unknown
PROPOSED LANDS USGS 1:24,000 Quadrangles were tied down with a minimum of four control points. Project boundaries were digitized onscreen using ArcEdit software with the USGS color infrared DOQQ's as a backdrop. Topology was generated using the ArcINFO BUILD command. Attribute items were added to the feature attribute table and the appropriate attribute assigned to each polygon. The method of choice now is to use heads-up digitizing on-screen with the DOQQ's as a backdrop in ArcEdit. Process Date: Unknown
GeoPlan downloaded this dataset from the Southwest Florida Water Management District website: (http://www.swfwmd.state.fl.us/data/gis/index.htm) in April 2005. The data was downloaded in shapefile format and was in the following projection: NAD_1983_HARN_UTM_Zone_17N. The dataset was projected to FGDL Albers HPGN. - Upcased all characters in the table - A DESCRIPT item was added based on the item PROJECTNAM. Process Date: 20050427
