Determination of water depth with high-resolution satellite imagery over variable bottom types Determination of water depth with high-resolution satellite imagery over variable bottom types

A standard algorithm for determining depth in clear water from passive sensors exists; but it requires tuning of five parameters and does not retrieve depths where the bottom has an extremely low albedo. To address these issues, we developed an empirical solution using a ratio of reflectances that has only two tunable parameters and can be applied to low-albedo features. The two...

Tropical Storm Isidore and Hurricane Lili: Louisiana barrier shoreline response, preliminary results Tropical Storm Isidore and Hurricane Lili: Louisiana barrier shoreline response, preliminary results

In a cooperative effort between the U.S. Geological Survey, National Aeronautics and Space Administration, University of New Orleans, and Louisiana's Department of Natural Resources, Louisiana's barrier islands were surveyed with airborne topographic lidar and oblique aerialphotography both before and after the impacts of 2002's Tropical Storm Isidore and Hurricane Lili. The surveys were...
