Accuracy
The State of Florida Division of Emergency Management LiDAR survey was collected under the guidance of a Professional Mapper/Surveyor.
The data was collected at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas.
Horizontal Positional Accuracy
All ground control processing and adjustment was performed using published coordinate horizontal and vertical datums (e.g. NGS CORS).
For deliverables, Corpscon for Windows Version 5.11.08 (geoid 03) was used for horizontal and vertical datum conversion as well as for
coordinate system conversion purposes (e.g. UTM to State Plane).
The horizontal accuracy baseline spec was for the data to meet or exceed a 3.8 ft horizontal accuracy at the 95% confidence level
using RMSE(r) X 1.7308 as defined by the FGDC Geospatial Positioning Accuracy Standards, Part 3: NSSDA. The horizontal accuracies for
each block were tested. To obtain the tested horizontal accuracy, please refer to the Survey Report for each block, which may be accessed at:
https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/520/supplemental/

https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/520/supplemental/ch2mhill_block_index_shapefile.zip
Vertical Positional Accuracy
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. 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, Geospatial National
Standard for Spatial Data Accuracy, Federal Geographic Data Committee Secretariat, Reston, Virginia, p.3-4). Additional steps were taken
to ensure the vertical accuracy of the LiDAR data including:
Step 1: Precision Bore sighting (Check Edge-matching)
Step 2: Compare the LiDAR data to the Field Survey (Field survey is to FEMA specifications and more stringent internal specifications)
Step 3: Automated Filtering
Step 4: Manual Editing (Quality Control)
Step 5: 3-D digitizing and Photogrammetric Compilation of hydrographic breaklines.
The vertical accuracy baseline spec was for the data to meet a fundamental vertical accuracy of 0.60 ft at the 95% confidence level
using RMSE(z) X 1.9600 (as defined by the ASPRS Guidelines: Vertical Accuracy Reporting for Lidar Data"). The vertical accuracies for
each block were tested. To obtain the tested vertical accuracy, please refer to the Survey or Vertical Accuracy Report for each block,

Completeness Report
The LAS files were flown at a density sufficient to support a maximum final post spacing of 4 feet for unobscured areas. The bare-earth
surface will contain voids in areas that were densely vegetated, covered by bridges, buildings, water, fresh asphalt, sand, etc.
Conceptual Consistency
The Light Detection and Ranging (LiDAR) LAS dataset is a topographic survey conducted for the State of Florida Division of Emergency
Management LiDAR Project. These data were produced for Florida Division of Emergency Management. 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 the data from
July 12, 2007 through February 8, 2008. The data was divided into 5000' by 5000' cells that serve as the final tiling scheme. The State of
Florida Division of Emergency Management LiDAR Survey was collected under the guidance of a Professional Mapper/Surveyor.
The Airborne Global Position System (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 of the aircraft. During the aerial survey laser
pulses reflected from features on the surface and 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 20 km radius from the flight survey area.
2008-02-08T00:00:00
The ABGPS, IMU, and raw scans are integrated using proprietary software developed by the Leica Geosystems and delivered with the
Leica ALS50 System. The resultant file is in a LAS binary file format. The LAS file version 1.1 format can be easily transferred from one
file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.).
The resultant points are produced in the Florida State Plane East Zone coordinate system, with units in feet and referenced to the
NAD83/90 HARN horizontal datum and NAVD88 vertical datum.
2008-02-08T00:00:00
The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary
filters is applied as appropriate for the production of bare-earth digital terrain models (DTMs). Interactive editing methods are applied
to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or
limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces.
2008-03-13T00:00:00
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 landcover, 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.

The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.1 format. The header file for each
dataset is complete as define by the LAS 1.1 specification. In addition the following fields are included: Flight Date Julian, Year, and Class.
The data were classified as follows:
Class 1 = Unclassified- this class includes vegetation, buildings, noise etc.;
Class 2 = Ground;
Class 7 = Noise;
Class 9 = Water;
Class 12 = Overlap.
The datasets were delivered in the 5000' by 5000' tiling scheme. 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 six character length and all files utilize
the LAS file extension.
