Airborne Laser Hydrography II

In 1985, Dr. Gary Guenther assembled the text, “Airborne Laser Hydrography” which quickly became a heavily used manual and guide for any and all scientists and engineers involved with airborne lidar bathymetry (ALB). It was a remarkable book that captured a snapshot of the state of the art of ALB and included historical developments, theoretical and modeling efforts as well as design characteristics and constraints, ending with accuracy assessment and a discussion of design tradeoffs. Known familiarly as the “Blue Book” it served the community remarkably well for many years. At 30 years of age, it is still a valued reference, but unavoidably dated in a field that has developed rapidly and nonstop over the intervening years. It is time for an update.

The new text is attempt by the ALB community to update and expand upon Guenther’s text. Like the original, Blue Book II reviews the historical developments in ALB, extending them into the 21^st century, considers basic environmental water optical properties, theoretical developments, data processing and performance evaluation. All have progressed dramatically in the past 30 years. This paper presents an outline of the new book, a description of the contents, with emphasis on the theoretical models of the lidar waveform and its propagation through, and interaction with the water.
