Purpose
|
|
This data was collected as part of an effort to map beach
|
|
topography efficiently and cheaply.

Notes
|
|
The Airborne LIDAR Assessment of Coastal Erosion (ALACE)
|
|
project was a partnership between NOAA, NASA, and U.S. Geological Survery
|
|
(USGS). It has been collecting baseline coastal topographic data for the
|
|
conterminous U.S. since 1996. NOAA left the partnership after the fall
|
|
2000 season, but USGS and NASA continue to collect data for research
|
|
purposes. This data may eventually be available via LDART. The ALACE
|
|
collections are typically targeted at a narrow strip of sandy beach and
|
|
are usually a kilometer or less in width. Many areas have both baseline
|
|
data and post-storm data. In general, this data has not been checked
|
|
with ground control, but has undergone internal consistency checks.
|
|
|
The acquisition of baseline coastal topographic data primarily occurs
|
|
during the fall, prior to winter erosion and when the beach is generally
|
|
at its widest due to sand accumulation over the summer months. However,
|
|
research missions are also conducted at other times to study the coastal
|
|
impacts of weather phenomena such as El Nino or hurricanes. All flights
|
|
are timed to occur within a few hours of low tide, when the beach is
|
|
most exposed.
