Using Leica Geosystems ALS50 Laser Systems, 89 flight lines with a nominal point spacing = 1.4 meters (4.59 feet)
were collected over Erie County, NY (approximately 1044 square miles). Multiple returns were recorded for each laser
pulse along with an intensity value for each return. The data acquisition occurred in missions on April 17, 2008
and April 28, 2008. During the LIDAR campaign, the field crew conducted a GPS field survey to establish final
coordinates of the ground base stations for final processing of the base-remote GPS solutions. This is a bare
earth classified data set; points are classified as ground or unclassified. Please note that water points are
sometimes classified as 'Unclassified' and other times as 'Ground'.
LIDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform.
Using a combination of laser range finding, GPS positioning and inertial measurement technologies; LIDAR instruments
are able to make highly detailed Digital Elevation Models (DEM) of the earth's terrain, man-made structures and vegetation.
This data was collected at a resolution to aid in coastal management decisions including flood plain analysis and mapping.

Reflective surface data represents the DEM created by laser energy reflected from the first
surface encountered by the laser pulse. Some energy may continue beyond this initial surface to be reflected by a
subsequent surface as represented by the Last Return data. Intensity information is captured from the Reflective
Surface pulse and indicates the relative energy returned to the sensor as compared to the energy transmitted. The
Intensity image is not calibrated or normalized but indicates differences in energy absorption due to the interaction
of the surface materials with laser energy at the wavelength transmitted by the sensor.

Horizontal Positional Accuracy
Contracted to meet 1 meter (RMSE) horizontal accuracy.
Vertical Positional Accuracy
LiDAR data accuracy determination shall employ the National Standard for Spatial
Data Accuracy (NSSDA). Contracted to meet 18.5cm (RMSE) on open bare terrain and 37.0cm for obscured areas.
Completeness Report
LIDAR raster data is visually inspected for completeness to ensure that any gaps between flight lines
or loss of signal represents less than 5% of required collection area. LIDAR is self-illuminating and has minimal cloud
penetration capability. Water vapor in steam plumes or particulates in smoke may cause reflection of LIDAR signals and
loss of elevation information beneath these plumes. Glass structures and roofs may appear transparent to the LIDAR signal
and therefore may not register on the reflective surface. Some asphalt formulations have been shown to absorb topographic
LIDAR wavelength energy resulting in "pitting" of roof surfaces using this material.
Conceptual Consistency
All LAS formatted LIDAR data are validated using commercial GIS software to ensure proper
formatting and loading before delivery. This validation procedure ensures that data on delivery media is in correct
physical format and is readable.
Data Collection: Using an Leica Geosystems ALS50 Laser Systems, 89 flight lines with a nominal

Airborne GPS Processing: Airborne GPS data was differentially processed and integrated with the post
processed IMU data to derive a smoothed best estimate of trajectory (SBET). The SBET was used to reduce the LiDAR slant
range measurements to a raw reflective surface for each flight line. The overlap between flight lines was removed to
provide a homogeneous coverage, and the coverage was classified to extract a bare earth digital elevation model (DEM).
Airborne GPS is differentially processed using the GrafNAV V7.50 software by Waypoint Consulting of Calgary, Alberta,
Canada. IMU data is processed using the PosPac V4.2 software by Applanix Corporation of Richmond Hill, Ontario, Canada.
The reflective surface is derived using the ALS Post Processor software by Leica Geosystems GIS & Mapping Division of
Atlanta, Georgia. The classification and quality control (QC) of LiDAR data is carried out using TerraScan software
by Terrasolid Limited of Helsinki, Finland.

The NOAA Office for Coastal Management (OCM) received the files in las format. The files contained Lidar
elevation and intensity measurements. The data were in State Plane New York West, FIPS 3103 coordinates, horizontal
units of measure of US survey feet and in NAVD88 Geoid 03 vertical datum with vertical units of measure of feet.
OCM performed the following processing to the data to make it available within the Digital Coast:
1. The data were converted from NY State Plane coordinates to geographic coordinates.
2. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid 03.
3. The LAS data were sorted by latitude and the headers were updated.
4. The data were filtered to remove outliers.

The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey.
Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org)
