The Delaware Geological Survey led a multi-agency, state and federal effort (including DelDOT, DNREC, USGS, and NOAA) to secure funds from the Hurricane Sandy Relief appropriation to collect new, high-quality LiDAR for the entire state of Delaware. LiDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure distances from a source to a target object. Typically, a LiDAR device is attached to the bottom of a plane and is pointed at the ground.

DGS, in cooperation with DNREC Delaware Coastal Programs, developed a series of coastal inundation maps corresponding to water surfaces from the mean higher-high water (MHHW) level to 7 feet above MHHW, in 1-foot increments.
