This metadata record describes the topographic mapping of Hancock and Jackson Counties, Mississippi during 2005. Using a combination
of laser rangefinding, GPS positioning and inertial measurement technologies; LIDAR instruments are able to make highly detailed
Digital Elevation Models (DEMs) of the earth's terrain, man-made structures and vegetation. This data was collected at submeter
resolution to provide nominal 5m spacing of collected points. Multiple returns were recorded for each pulse in addition to
an intensity value using a Leica ALS-50 Aerial Lidar Sensor.

Use limitation statement:
These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that
temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual
surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.
Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data
are NOT to be used for navigational purposes.

Use Limitation
While every effort has been made to ensure that these data are accurate and reliable within the limits of the current state
of the art, NOAA cannot assume liability for any damages caused by any errors or omissions in the data, nor as a result of
the failure of the data to function on a particular system. NOAA makes no warranty, expressed or implied, nor does the fact
of distribution constitute such a warranty.

Source Contribution: Ground Control. Kevin Chappell, of Terrasurv and under contract to EarthData International established
at total of 40 survey points within Jackson and Hancock Counties, MS. The survey was completed in two phases; the first phase
consisted of 8 lidar control points in southern Jackson County. The second phase consisted of 12 additional lidar control
points in Jackson County and 20 new lidar control points in Hancock County. Source Type: electronic mail system

Source Contribution: Aerial Lidar Acquisition. EarthData Aviation., was contracted by EarthData International to collect ALS-50
Lidar data over Hancock and Jackson Counties, Mississippi. The project site was flown on February 25 and March 1, 10, 11,
and 12 using its aircraft with tail number N2636P. Lidar data was captured using an ALS-50 Lidarsystem, including an inertial
measuring unit (IMU) and a dual frequency GPS receiver. Lidar was obtained at an altitude of 3,658 meters (12,000 feet) above
mean terrain, at an average airspeed of 145 knots. Sensor pulse rate was set at 29,900 Hz with a field of view of 45 degrees
and a scan rate of 17 Hz. Average swath width of the collected raw lines is 3,100 meters. Point spaing was 5 meters. Lidar
data was recorded in conjunction with airborne GPS and IMU; the stationary GPS receiver was positioned over a control point
located at the airport. Recorded digital data was shipped via external hard drive to the production facility for processing.
During airborne data collection, an additional GPS receiver was in constant operation over a published National Geodetic Survey
(NGS) control point at at KHSA (Stennis International) Airport. The coordinate value for temporary control point STENNIS (BH2999)
was determined by a network adjustment to CORS stations MOB1 and NDBC , both of which were tied to the project control network.
During the data acquisition, the receivers collected phase data at an epoch rate of 1 Hz. All GPS phase data was post processed
with continuous kinematic survey techniques using "On the Fly" (OTF) integer ambiguity resolution. The GPS data was processed
with forward and reverse processing algorithms. The results from each process, using the data collected at the airport, were
combined to yield a single fixed integer phase differential solution of the aircraft trajectory. Source Type: Firewire Drive

evaluation Method Description
The lidar data fully comply with FEMA guidance as published in Appendix A, February, 2002.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description
The lidar data fully comply with FEMA guidance as published in Appendix A, February, 2002 and National Standard for Spatial
Accuracy (NSSDA). The vertical accuracy was tested following the National Standards for Spatial Data Accuracy. Based on a
total of 32 points the average error between the bare earth LiDAR coverage and the control was 0.004 m with a root mean square
error (RMSE) of 0.120 m.
Completeness Commission
evaluation Method Description
1. EarthData's proprietary software, Checkedb, for verification agianst ground survey points. 2. Terrascan, for verification
of automated and manual editing and final QC of products.
ConceptualConsistency
measure Description
Compliance with the accuracy standard was ensured by the placement of GPS ground control prior to the acquisition of lidar
data. The following checks were performed. 1. The ground control and airborne GPS data stream were validated through a fully
analytical boresight adjustment. 2. The DTM (Digital Terrain Model) data were checked against the project control. 3. Lidar
elevation data was validated through an inspection of edge matching and visual inspection for quality (artifact removal).
