Abstract

This Light Detection and Ranging (LiDAR) classified (ASPRS LAS classifications) dataset is a topographic survey conducted for

the Task Order 007 Aerial Survey 2010 project. This data was produced for the US Army Corps of Engineers (USACE) Joint Airborne Lidar

Bathymetry Technical Center of Expertise (JALBTCX). The LiDAR point cloud was flown at a density sufficient to support a maximum final

post spacing of 1 point per meter. 3001 International Inc. acquired flightlines between April 9 - 26, 2010. The Task Order 007 Aerial

Survey 2010 was collected under the guidance of a Professional Mapper/Surveyor. The area of coverage includes portions of the coastline

of Louisiana in the counties of Lafourche, Plaquemines, and Terrebonne, and along the south coast of Lake Pontchartrain in Jefferson and

St. Charles counties. The area of coverage for Mississippi includes the barrier islands in Harrison and Jackson counties.

In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record.

Data Quality

Accuracy:

The Task Order 007 survey 2010 project 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 1 point per meter.

Horizontal Positional Accuracy:

All ground control processing and adjustment is 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).

; Quantitative Value: 0.5 meters, Test that produced the value: Not provided

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)

; Quantitative Value: 0.15 meters, Test that produced the value: See Vertical Positional Accuracy Report

Completeness Measure:

Cloud Cover: 0

Completeness Report:

The LAS files were flown at a density sufficient to support a maximum final post spacing of final post spacing of 1 point per meter.

Conceptual Consistency:

The Light Detection and Ranging (LiDAR) LAS dataset is a topographic survey conducted Task Order 007 year 2010. This data was produced

for US Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX).

Process Steps

Process Step 1

CC ID: 1132341
Description:

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.

Process Date/Time: 2010-07-01 00:00:00

Process Step 2

CC ID: 1132342
Description:

The ABGPS, IMU, and raw scans are integrated using proprietary software developed by Optech and delivered with the Optech ALTM Gemini

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 referenced to the Geographic NAD83 horizontal datum and NAVD88 vertical datum.

Process Date/Time: 2009-05-27 00:00:00

Process Step 3

CC ID: 1132343
Description:

The data is 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 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.
