        abstract:  The Light Detection and Ranging (LiDAR) LAS dataset is a survey of select areas within Southwest Florida. These data were produced for the Southwest Florida Water Management District (SWFWMD). Two SWFWMD datasets are included in this metadata record; they are Peace River South and Carter Creek. The Carter Creek portion of this data is a small data set in the northwestern part of Highlands County, which has been appended to the larger data set of Peace River South for ease of use within the NOAA Coastal Services Center (CSC) Lidar Data Retrieval Tool (LDART). Information that is specific to each data set has been maintained. PEACE RIVER SOUTH The Peace River South LiDAR (P692)Survey project area consists of approximately 1,801 square miles and covers Hardee and DeSoto Counties and portions of Highlands and Charlotte Counties. The LiDAR point cloud was flown at a density sufficient to support a maximum final post spacing of 6 feet for unobscured areas. 3001 inc. acquired 445 flightlines between February 11, 2005 and April 14, 2005. The data was divided into 5000' by 5000' foot cells that serve as the tiling scheme. The Peace River South LiDAR Survey was collected under the guidance of a Professional Mapper/Surveyor. CARTER CREEK The Carter Creek LiDAR Survey project area consists of approximately 26 square miles and is located in northwestern Highlands County. The LiDAR point cloud was flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas. 3001 Inc. acquired 60 flightlines between February 6, 2006 and February 7, 2006. The data was divided into 5000' by 5000' foot cells that serve as the tiling scheme. The Carter Creek LiDAR Survey was collected under the guidance of a Professional Mapper/Surveyor.
        purpose:  The Southwest Florida Water Management District uses topographic information to support regulatory, land management and acquisition, planning, engineering, and habitat restoration projects. The Peace River South and Carter Creek LiDAR Survey data will support the creation of Federal Emergency Management Agency Flood Insurance Rate Maps (FEMA FIRM) and an integrated ground and surface water model for the Peace River Watershed. All data will be public record as defined by applicable Florida statutes. The Peace River South and Carter Creek LiDAR Survey were collected under the guidance of a licensed and professional Surveyor and Mapper.
        credit:  Acknowledgement of the Southwest Florida Water Management District would be appreciated in products derived from these data.

            evaluationMethodDescription:  PEACE RIVER SOUTH The accuracy assessment was performed using a standard method to compute the root mean square error (RMSE) based on a comparison of ground control points (GCP) and filtered LiDAR data points. Filtered LiDAR data has had vegetation and cultural features removed and by analysis represents bare earth elevations. Testing was performed prior to gridding of the filtered LiDAR data points and construction of the Intergraph .dtm file format. The RMSE figure was used to compute the vertical National Standard for Spatial Data Accuracy (NSSDA). Ground control was established by 3001, Inc. A spatial proximity analysis was used to select edited LiDAR data points contiguous to the relevant GCPs. A search radius decision rule is applied with consideration of terrain complexity, cumulative error and adequate sample size. Cumulative error results from the errors inherent in the various sources of horizontal measurement. These sources include the airborne GPS, GCPs and the uncertainty of the accuracy of the LiDAR data points. This accuracy is achieved prior to the sub sampling that occurs through integration with the inertial measurement unit (IMU) positions that are recorded. It is unclear at this time whether the initial accuracy is maintained. The horizontal accuracy of the GCPs is estimated to be in the range of approximately 1 to 1.6 inches. Finally, sample size was considered. The specification for the National Standard for Spatial Data Accuracy is a minimum of 20 points to conduct a statistically significant accuracy evaluation (Minnesota Planning, 1999, Positional Accuracy Handbook, Minnesota Planning Land Management Information Center, St. Paul, Minnesota., p.3). Most statistical texts indicate that a minimum of 30 sample points provide a reasonable approximation of a normal distribution. The intent of the NSSDA is to reflect the geographic area of interest and the distribution of error in the data set (Federal Geographic Data Committee, 1998, Geospati

                description:  The ABGPS, inertial measurement unit (IMU), and raw scans are collected during the LiDAR aerial survey. The ABGPS monitors the xyz position of the sensor and the IMU monitors the orientation. During the aerial survey laser pulses reflected from features on the ground surface are detected by the receiver optics and collected by the data logger. GPS locations are based on data collected by receivers on the aircraft and base stations on the ground. The ground base stations are placed no more than 35 km radius from the flight survey area. Process date for Carter Creek is 2006.

                description:  Filtered and edited data are subjected to rigorous QA/QC according to the 3001 Inc. Quality Control Plan and procedures. Very briefly, a series of quantitative and visual procedures are employed to validate the accuracy and consistency of the filtered and edited data. Ground control is established by 3001, Inc. and GPS-derived ground control points (GCPs) points in various areas of dominant and prescribed land cover. These points are coded according to land cover, surface material and ground control suitability. A suitable number of points are selected for calculation of a statistically significant accuracy assessment as per the requirements of the National Standard for Spatial Data Accuracy. A spatial proximity analysis is used to select edited lidar data points within a specified distance of the relevant GCPs. A search radius decision rule is applied with consideration of terrain complexity, cumulative error and adequate sample size. Accuracy validation and evaluation is accomplished using proprietary software to apply relevant statistical routines for calculation of Root Mean Square Error (RMSE) and the National Standard for Spatial Data Accuracy (NSSDA) according to Federal Geographic Data Committee (FGDC) specifications. Process date for Carter Creek is 20060807-20060914.

                description:  The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.0 format. The header file for each dataset is complete as define by the LAS 1.0 specification. In addition the following fields are included: Flight Date Julian, Year, and Class. The LAS files do not include overlap. The data was classified as follows: Class 1 = Unclassified. This class includes vegetation, buildings, noise etc. Class 2 = Ground Class 3 = Water The datasets were delivered in the Districts standard 5000' by 5000' tiling scheme. The tiles are contiguous and do not overlap. The tiles are suitable for seamless topographic data mosaics that include no "no data" areas. The names of the tiles are left padded with zeros as required to achieve a five character length and all files utilize the LAS file extension. The South Peace LiDAR Survey was filtered and edited using LiDAR profiles, aerial imagery, and stereo pairs that were created from LiDAR intensity images. The South Peace LiDAR datasets have gone through extensive QC procedures by 3001 and the Southwest Florida Water Management District. During the QC, 3001 used the following principals to guide their filtering, editing, and QC decisions: All of the data sets were reviewed and the breaklines were created using stereo pairs that were generated from the GeoCue LiDARgrammetry software. In addition, imagery was used during the editing / and breakline creation processes and during the final review of the data sets. If the imagery and the LiDAR did not agree, 3001 used the LiDAR profiles as a guide in areas where the profiles were adequate. In areas where the point density was not sufficient enough to use as a guide, 3001 relied on the imagery and created obstruction polygons. If an area changed between the Imagery acquisition and the LiDAR acquisition, 3001 followed the LiDAR as a guide. 3001 used the LiDAR and the imagery to create breaklines. In some instances, the breaklines do not reflect the imagery due to a significant amount of rain during acquisition. The following paragraph is from the South Peace metadata. "There was significant rain fall during the acquisition of the South Peace LiDAR survey. According to the gage at the USGS 02295637 Peace River at Zolfo Springs Florida, the gage height went from approximately 14.3 feet to 17.3 feet between February 28, 2005 and March 2, 2005. Between March 2, 2005 and March 4, 2005 the gage fell to about 15.1 feet. The changes in the channel are evident in the breaklines. In some areas there are sudden changes in the size of the channel as well as the elevation of the breaklines. Due to the inconsistencies in the channel we have created obscured polygons around the affected channels." In areas of dense vegetation the bare-earth surface may appear rough in nature. This is due to the scarcity of points in the area or the uneven nature of the ground. Quality Control Procedures were performed by different people and using different methods during the project. Due to this, there may be different interpretations of the bare-earth surface in areas of dense vegetation. The main difference in the surfaces is the amount of points that each editor removed from the profile to represent the ground. This does not mean that either editor was incorrect in their calculations; it means that some editors were able to describe the surface with less points. The process date for this step is 2005/2006. The process date for Carter Creek for this step is 20060921.

                description:  The NOAA Coastal Services Center (CSC) received the files in LAS format. The files contained Lidar intensity and elevation measurements. The data was in Florida State Plane Projection and NAVD88 vertical datum. CSC performed the following processing to the data to make it available within the LDART Retrieval Tool (LDART): 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 Geoid 99. 3. The LAS data were sorted by latitude and the headers were updated.

                description:  The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
