| 2005-2006 Southwest Florida Water Management District (SWFWMD) Lidar: Polk County
(Including Hampton, Judy, Lake Wales, Peace River (North), and Polk District Remainder
Tracts) |
| This data set is one component of a digital terrain model (DTM) for the SWFWMD Polk
District. This record includes information about the LiDAR data for the following
SWFWMD tracts: Hampton, Judy, Lake Wales, Peace River (North) and Polk Remainder.
All of these tracts are located in Polk County. Please see the Bounding Coordinates
for each tract for the location within Polk County. Information that is specific to
each tract has been maintained. HAMPTON TRACT This data set is one component of a
digital terrain model (DTM) for Hampton Tract, Polk County, Florida encompassing approximately
43 square miles. This dataset is comprised of 48 LiDAR files, based on the DISTRICT
5,000’ by 5,000’ sheet index system (17951-17958, 18114-18121, 18363-18370, 18526-18533,
18259-18266 and 18594-18601) in the LAS file format. The raw data was collected at
an average ground sample distance of 1-meter. Other components of the DTM include:
3-D breaklines along hydrographic features in the Shape file format; lake/pond polygons
(in 3D) in the shape file format; obscured area polygons (in 2D) in the Shape file
format; and hard/soft breaklines (in 3D) in the Shape file format. Date of Collection:

Coordinate: 28.238391 JUDY TRACT This data set is one component of a digital terrain
model (DTM) for Judy Tract, Polk County, Florida encompassing approximately 12.6 square
miles. This dataset is comprised of 14 LiDAR files, based on the DISTRICT 5,000’ by
5,000’ sheet index system (17632-17636, 17795-17799, and 17959-17962) in the LAS file
format. The raw data was collected at an average ground sample distance of 1-meter.
Other components of the DTM include a personal geodatabase containing: obscured vegetation
polygons; road overpass polygons; road breaklines; soft feature breaklines; water
body polygons; coastal shorelines; 1-foot contours; hydrographic feature breaklines,
and island polygons in accordance with the SWFWMD 2006 Topographic Database Design.

28.238391 POLK DISTRICT REMAINDER This dataset is one component of a digital terrain
model (DTM) for the Southwest Florida Water Management District’s FY2007 Remainder
Polk District LiDAR Mapping Project and Polk District Contours Project (L672) encompassing
approximately 428 square miles in Polk County, Florida. This dataset is comprised
of 478 LiDAR files, based on the FL Statewide 5,000’ by 5,000’ sheet index system
in the LAS version 1.1 file format. LiDAR acquisition dates were January 27, January
30 through February 20, 2005. The raw data was collected at an average ground sample
distance of 2.1 feet. Other components of the DTM include a personal geodatabase in
accordance with the SWFWMD 2006 Topographic Database Design containing: obscured vegetation
polygons; road overpass polygons; road breaklines; soft feature breaklines; water
body polygons; coastal shorelines; hydrographic features breaklines; island polygons;
and 1-foot contours. Final products include FEMA-compliant LIDAR-derived DTM data
and 1-foot contours (for cartographic visualization purposes only) meeting or exceeding
National Map Accuracy Standards for 2-foot contours. This area is not a tract, but
an addition of areas to the Polk District data set. This data set consists of three
areas within Polk County. The approximate bounding coordinates for each area are given
below. Area 3 borders the east and north sides of the Peace River (North) and Judy
Tract data sets. The bounding coordinates for Area 3 are generalized here, but it
is actually a multi-sided polygon with many vertices. Date of Collection: 20050127,
