This data set is one component of a digital terrain model (DTM) for the Southwest Florida Water Management District's
FY2006 Digital Orthophoto (B089) and LiDAR Project (L470/L471), encompassing approximately 1,216 square miles across
Citrus and Sumter counties. The 2006 LiDAR dataset is comprised of 3-D masspoints delivered in the LAS file format
based on the District's 5,000' by 5,000' grid (1,356 cells). The other DTM component is 2-D and 3-D breakline features
in the ESRI ArcGIS Personal Geodatabase format. In accordance with the 2006 SWFWMD Topographic Database Design,
the following breakline features are contained within the database: closed water bodies (lakes, reservoirs, etc)
as 3-D polygons; linear hydrographic features (streams, canals, swales, embankments, etc) as 3-D breaklines;
coastal shorelines as 3-D linear features; edge of pavement road features as 3-D breakines; soft features
(ridges, valleys, etc.) as 3-D breaklines; obscured vegetation polygons as 2-D polygons; overpasses and bridges
as 3-D breaklines; 1-foot contours for visualization purposes; and island features as 3-D polygons. This data falls
in Citrus and Sumter Counties.
Intensity values, or the measure of reflectance of the laser are also captured.
Breakline features were captured to develop a hydrologically correct DTM. Contours (1-foot) were generated from
the DTM that meet the National Map Accuracy Standards for 2-foot contours (FEMA specifications). Bare earth LiDAR
masspoint data display a vertical accuracy of at least 0.3-feet root mean square error (RMSE) in open unobscured areas

This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
The DTM was developed to support the DISTRICT's regulatory, land management and acquisition, planning,
engineering, and habitat restoration projects

Horizontal Positional Accuracy
The intended hroizontal accuracy is consistent with features on digital
orthophotographs that meet National Map Accuracy Standards at a scale of 1:1200. 3.6 feet horizontal
accuracy at the 95% confidence level, not tested.
Vertical Positional Accuracy
The intended vertical accuracy of this project is 0.59-feet (95% confidence level) vertical.
RMSE= 0.3 feet for unobscured points, not tested.

Completeness Report
All elevation measurements within the bounding coordinates of this XML were used to derive this dataset.
Conceptual Consistency
The LiDAR DTM was developed in accordance with the 2006 SWFWMD LiDAR specifications.
The DTM is intended to support 2-foot contours, and the vertical accuracy of ground points in unobscured areas
is 0.3-feet RMSE.
The LiDAR data was acquired using a Leica ALS50 from an altitude of 2,400' above ground level to provide an
nominal ground sample distance of 2.4-feet. The scanner field of view was 28-degrees, and the scan rate was 46-hertz.
First and last return data was collected along with the signal return intensity. A total of 278 flights of LiDAR data
were acquired. Flight lines were flown with a 30% sidelap, providing a line-to-line swath width of 957-feet.
Thirty (30) Two redundant airborne GPS bases stations were utilized during the data acquisition with maximum
line-of-sight distance between the base station and aircraft of 20-km.
The LiDAR data was reduced using Grafnav (Waypoint Consulting) for GPS post-processing, PosProc (Applanix Crop) for
IMU processing, ALS50 Post Processor (LH Systems) to initial LiDAR processing, TerraScan (Terrasolid) for initial point
classification, and proprietary Woolpert developed software for refining the point classification and QC.
The LAS files contain 5 classifications: 1 = unclassified; 2 = ground; 9 = water; and 10 = photogrammetric mass
points and 11=swamp/wetland points. The class 1 consists of all points not on the ground. Class 2 consists of bare
earth points. Class 9 points are those points falling within lake/pond polygons. Class 10 consists of supplementary
mass points that were photogrametrically compiled on points features suchs as peaks or pits, and they were created to
maintain the accuracy of the DTM. Class 11 consists of points within swamps and/or wetlands polygons classified as ground.

Metadata imported.
The NOAA Office for Coastal Management (OCM) received the the files in LAS
format. The files contained Lidar elevation measurements. The data was in Florida State Plane Projection
and NAVD88 vertical datum. OCM performed the following processing to the data to make it available within
the Digital Coast Data Access Viewer (DAV):
1. The data were converted from Florida State Plane West coordinates to geographic coordinates.
2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid03.
3. The LAS data were sorted by latitude and the headers were updated.

The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
