Abstract:
This data set includes data collected in October 1997 over the Sacramento, CA, floodplain.
Laser mapping uses a pulsed laser ranging system mounted onboard an aircraft to measure ground
elevation and topography. The laser emits laser beams at high frequency and is directed downward at the
earth's surface through a port opening in the bottom of the aircraft's fuselage. The laser system records the
time difference between emission of the laser beam and the reception of the reflected laser signal in the
aircraft. The aircraft travels over the beach at approximately 60 meters per second while surveying from
the low water line to the landward base of the sand dunes.

Supplemental Information:
This data set was collected with a LIDAR (LIght Detection And Ranging) instrument designed and developed by
the Observational
Sciences Branch (OSB) of NASA at the Wallops Flight Facility in Virginia. The instrument, originally designed
for mapping ice sheets
in Greenland, is called the Airborne Topographic Mapper or ATM. The ATM II (the latest version), operates with
a Spectra Physics
laser transmitter, which provides a 7 nanoseconds long, 250 microjoules pulse at a frequency-doubled
wavelength of 523 nanometers
in the blue-green spectral region. The laser transmitter can function at pulse rates from 2 to 10 kilohertz
(kHz). The laser system
with a separate cooling unit weighs approximately 45 kilograms (kg) and requires approximately 15 amperes of
power at 115 volts.
The transmitted laser pulse is reflected to the surface of the earth with the aid of a small folding mirror
mounted on the back of a
secondary mirror of a rotating scan mirror assembly mounted directly in front of the telescope. The scan
mirror, which is rotated at 20
hertz, is comprised of a section of round aluminum stock, machined to a specific off-nadir angle. A scan
mirror with the off-nadir
angle of 15 degrees was utilized, producing an elliptical scan pattern with a swath width equal to 50 percent
of the approximately
700-meter aircraft altitude. The reflected laser pulse is transmitted to a photo-multiplier assembly that
consists of a lens, a
narrow bandpass filter, and a single photomultiplier tube.
Note: The Spatial Reference section of this document may lack fully FGDC-compliant information regarding
projection parameters
(i.e., Central meridian, false Northing, etc.). The State Plane or UTM Zone will be supplied, and the
corresponding parameters can be
found in Appendix C of: Snyder, John, 1987, Map Projections, a Working Manual (U.S. Geological Survey
Professional Paper 1395):

The ATM LIDAR elevation measurements have been found to be within +/- 15 centimeters of each other in

surveys the differences
are between +/- 15 to 20 centimeters. The accuracy of the majority of the data is estimated to be

Description:
The vertical values in this data set have been filtered through visual inspection to find abnormally
high and abnormally low values.
In addition, this data was processed using a spatial filtering program that identifies and discards
outlier elevation measurements.
This program reads each elevation measurement within a file and identifies "spatially close" points
(i.e. those neighboring points
within a fixed radius of the point). The mean and standard deviation is calculated using the
elevations of these points. If the
elevation difference from the mean of the point under consideration is more than 2 standard deviations
and greater than a defined
distance the point is discarded.
