The use of technology has improved throughout the years. The instruments now have faster processing, more accurate readings, and lighter and more compact. This paper will investigate how these technologies are being use for the assessment of the damages of Super Storm Sandy. Two equipment instruments, LIDAR and Ground Penetrative Radar (GPR) will be covered in the assessment. The following questions will be answered with respect to said equipment:
1. Reestablishment of the limits of the shore line
2. Location of streets and foundations of houses destroyed/moved by the storm
3. Analysis of buildings moved/damaged by the storm in determining whether a building is structural sufficient or needs to be demolished.
4. Safety of the boardwalk and its infrastructure.
a. Structural integrity of the boardwalk, its foundation and the associated structures located on and along the Boardwalk.
b. The safety and condition of the infrastructure that supports the Boardwalk and its features with respect to the fire that occurred after last summer that destroyed the rebuilt Boardwalk.
LIDAR (Light Detection and Ranging) is a remote sensing method that uses light in the form of a pulsed laser to measure distances to the Earth. These light pulses – combined with other data recorded by the airborne system – generate precise, three-dimensional information about the shape the Earth and its surface characteristics. There are two types of LIDAR, topographic, and bathymetric. Topographic LIDAR uses a near-infrared laser to map the land while bathymetric LIDAR uses water-penetrating green light to measure seafloor and riverbed elevation. LIDAR can be used to map the limits of the reestablished shore line by having the ability to collect ...
