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, 20050130-20050220 Bounding Coordinates of Area 1: Area 2 Area 3

name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description
HAMPTON TRACT, JUDY TRACT, LAKE WALES, PEACE RIVER (NORTH) The intended horizontal accuracy is consistent with features on
digital orthophotographs that meet National Map Accuracy Standards at a scale of 1:1200. Compiled to meet 1.1 m (3.6-feet)
horizontal accuracy at the 95% confidence level, not tested. POLK COUNTY REMAINDER Horizontal accuracy shall be tested to
meet or exceed a 1.37 m (4.5 foot) horizontal accuracy at 95 percent confidence level using RMSE(r) x 1.7308 as defined by
the National Standard for Spatial Data Accuracy (NSSDA).
