Airborne Lidar Bathymetry

Mapping Shallow Rivers Under Low-flow Conditions
Although operational for more than twenty years, Airborne Lidar Bathymetry (ALB) has rarely been used in riverine areas. The US Bureau of Reclamation adopted it to study how flow change in the Yakima Rivera affected fish habitat. The authors show that ALB offers accuracy and precision at least as good, if not better than that achieved in typical survey by boat with sonar and GPS. The United States Bureau of Reclamation needed to create an accurate hydraulic model of the Yakima River in Washington State to study how changes in river flow would effect downstream fish habitat. For many years... (read more)

The Increasing Importance of Satellite-derived Bathymetry

Effective Surveying Tool For The Shallow Water Zone
Bathymetric data in the shallow water zone is of increasing importance to support various applications such as safety of navigation, reconnaissance surveys, coastal zone management or hydrodynamic modelling. A gap was identified between data demand, costs and the ability to map with ship and airborne sensors. This has led to the rise of a new tool to map shallow-water bathymetry using multispectral satellite image data, widely known as Satellite Derived Bathymetry (SDB). Read on for an article providing an overview of the SDB methods, showing how data can be integrated into survey campaigns and highlighting three use cases. (By Knut Hartmann,... (read more)

Using 3D Printer Technology to Represent Survey Information

The Art of Bathymetry
Great advancements have been made in three dimensional printing over the last few years and have made an impressionable impact across a variety of industries. 3D printing's versatility can be incorporated into any industry that has some form of three dimensional design. An exciting application is to model point clouds from survey techniques to create three dimensional scaled models for visualisation and communication. This article explores a new medium using 3D printed technology.  (By Andrew Ternes, Port of Melbourne and Dr Daniel Ierodiaconou, Deakin University, Australia) Over the last few years great advancements have been made to all forms of...

First High-resolution Map of the Great Barrier Reef Released

One and a half million square kilometres of bathymetric seafloor data have been released to the public by Geoscience Australia under partnership with James Cook University and the Australian Hydrographic Service of the Great Barrier Reef. The project carried out high-resolution bathymetric scans, which were combined with existing datasets held by the government to create the most comprehensive, detailed models produced to date. The release comes as the federal government announced an AU$60 million investment in protective measures for the Great Barrier Reef, which include measures to shield the Reef from polluted water, and investment in Australian Institute of Marine...
