Process Steps
Process Step 1
| Description: |
HAMPTON TRACT, JUDY TRACT, LAKE WALES, PEACE RIVER (NORTH) The LiDAR data was acquired using a Leica ALS50 from an altitude of 1,000-meters above ground level to provide an average ground sample distance of 1-meter. The scanner field of view was 44-degrees, and the scan rate was 33-hertz. First and last return data was collected along with the signal return intensity. 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 4 classifications: 1 = unclassified; 2 = ground; 9 = water; and 10 = photogrammetric mass points. The class 1 consists of all points not on the ground. Class 2 consists of bare earth points. Class 9 consists of points within water polygons such as swamps and/or wetlands. Class 10 consists of supplementary mass points that were photogrametrically compiled on points features such as as peaks or pits, and they were created to maintain the accuracy of the DTM.

Process Step 2
| Description: |
POLK REMAINDER The LiDAR data was acquired using a Leica ALS50 from an average altitude of 3,000-feet above ground level to provide an average ground sample distance of 3.3-feet. The scanner field of view was 44-degrees, and the scan rate was 33-hertz. First and last return data collected along with the signal return intensity. 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 LiDAR data was reviewed in 3D using a digital photogrammetric work station using ADS40 digital stereo imagery. The LiDAR ground points are adjusted, if needed, to fit the ground. Breaklines were added to hydrologically enforce the DTM. The edited LiDAR data and the photogrammetrically compiled breaklines are merged and processed to create the final DTM files. During the production process, LiDAR data gaps between the flight lines were observed. These gaps between flight lines were corrected by adding photogrammetrically compiled mass points. These points are classified as class 10, in the LAS file. In the areas with the compiled masspoints, it may be noted that the masspoints are not as dense the areas with complete LiDAR coverage. The masspoints were compiled at a sufficient density to define the surface to contract specifications. Anomalies were noted in the 2005 Peace River North and Hampton Tract LiDAR data, during the LiDAR QA/QC process for the 2007 Remainder Polk County Project. The 2005 LiDAR datasets for Peace River North (P692) and Hampton Tract (DO19) required additional processing to ensure correct ground points classification. In areas with gaps in the LiDAR coverage, photogrammetrically compiled masspoints were added to the surface data. The LAS files contain 5 classifications: 1 = unclassified; 2 = ground; 9 = water; 10 = photogrammetric masspoints; and 11 = swamp and/or wetlands. The class 1 consists of all points not considered to be ground. Class 2 consists of bare earth (ground) points. Class 9 consists of points within water polygons. Class 11 consists of point within swamps and/or wetlands. Class 10 consists of supplementary mass points that were photogrametrically compiled on points features such as peaks or pits, and LiDAR data gaps. These points were created to maintain the accuracy of the DTM. 3D breaklines were collected at the digital photogrammetric workstation during the LiDAR data review. These breaklines were delineated to insure the DTM is hydrologically correct. Hydrologically Enforced Elevation Data is defined as "Hydro enforced TINS, DEMS, or contours ensure that top surfaces of bridges and culverts are cut by stream breaklines so that computer models will accurately represent drainage flow" per FEMA's Appendix A A.4.10. The breaklines were collected for hydrologically significant features as appropriate to support the development of the generation of 2-foot contours meeting National Map Accuracy Standards. The following breakline features were classified and separated: Closed Water Body Features, Linear Hydrographic Features, Coastal Shorelines, Road Features, Soft Features, Obscured Vegetated Areas, Island Features, Overpasses, and Bridges. Per contract specifications, culverts were not collected as part of this project. Therefore continuity of hydrographic features may not be consistent. For a complete description of survey methods, processing methods, software, system parameters, and accuracy analysis, see the Florida MTS Report of Specific Purpose Survey, SWFWMD MTS Report of DOI Survey, FY2007 Digital LiDAR (L672) (dated 4/8/2008)). |

The NOAA Office for Coastal Management (OCM) received the files in LAS format. The files contained Lidar elevation measurements.
