The landslide has created natural dams of Salmon Falls Creek, resulting in the development of large lakes and a potential flooding hazard. Rapid motion (em/year-m/year) of the relatively remote landslide was first reported in 1999, but significant horizontal motion (up to 10.8 m) is demonstrated between 1990 and 1998 by measuring changes in the locations of ground control points in a time-series of images. The total (three-dimensional) motion of the landslide prior to 2002 was calculated using the horizontal (two-dimensional) velocities obtained in the image change detection study and horizontal-to-vertical ratios of motion derived for the landslide in 2003-2004 collected from a network of autonomous GPS stations. The total historical motion that was estimated using this method averages about 12 m, which is in agreement with field observations.

Application of SeaWinds scatterometer and TMI-SSM/I rain rates to hurricane analysis and forecasting / R. Atlas in ISPRS Journal of photogrammetry and remote sensing, vol 59 n° 4 (June - July 2005)

The impact of the precipitation estimates produced by the TRMM Microwave Imager (TMI) and Special Sensor Microwave/lmager (SSM/I) in a previously developed 1D variational continuous assimilation algorithm for assimilating tropical rainfall is shown on two hurricane cases. Results on the impact of the SeaWinds scatterometer on the intensity and track forecast of a mid-Atlantic hurricane are also presented. This work is the outcome of a collaborative effort between NASA and NOAA, and indicates the substantial improvement in tropical cyclone forecasting that can result from the assimilation of space-based data in global atmospheric models.

Airborne laser swath mapping: quantifying changes in sandy beaches over time scales of weeks to years / Ramesh L. Shrestha in ISPRS Journal of photogrammetry and remote sensing, vol 59 n° 4 (June - July 2005)

Each year, a segment of the Florida coastline will be mapped using Airborne Laser Swath Mapping (ALSM) technology (also referred to as LIDAR). The ALSM surveys, conducted by UF staff and students, nominally extend from a few hundred feet offshore to about 1500 ft inland. GPS observations are manually collected by FDEP personnel and used to generate profiles across the beach for comparison with profiles generated from the ALSM observations. Results from the first survey segment completed under the program, covering approximately 35 miles of beaches in northeast Florida, are presented. Additional results that demonstrate the ability to precisely quantify changes in beach topography and volume using ALSM data are also presented.
