Airborne Topographic data (LIDAR) of field activity A-1-99-TX in Gulf Coast from 10/16/1999 to 10/16/1999, http://walrus.wr.usgs.gov/infobank/a/a199tx/html/a-1-99-tx.meta.html. These data and information are intended for science researchers, students from elementary through college, policy makers, and general public. Equipment Used - LIDAR 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. <BR> 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. Similar information is available for thousands of other USGS/CMG-related Activities. If known, available are Activity-specific navigation, gravity, magnetics, bathymetry, seismic, and sampling data; track maps; and equipment information; as well as summary overviews, crew lists, and information about analog materials.
