The Laser Altimeter Processing Facility (LAPF) at NASA's
Goddard Space
Flight Center is dedicated to processing and distributing data products
acquired by experimental airborne and spaceborne laser altimeters developed
within Goddard's Laboratory for Terrestrial Physics. The LAPF has been
established to support NASA's
Topography and Surface Change Program,
Natural Hazards Program, and other Solid Earth Science research activities.
The LAPF is developing algorithms and methodologies for processing
experimental surface lidar and wide-swath scanning systems. The data
products being generated are therefore evolving, yielding topography
measurements of increasing accuracy. For all the systems, laser ranging
data is combined with knowledge of platform position and attitude in order
to yield topographic data referenced to geodetic coordinates. Standard
data products from three instruments are being produced under the auspices
of the LAPF: the airborne SLICER and RASCAL instruments and the spaceborne
series of SLA instruments. An additional airborne laser altimeter system,
ATM, is also providing data in support of NASA's Solid Earth Science
programs. ATM data is acquired and processed by the Observational Science
Branch within Goddard's Laboratory for Hydrospheric Processes.
