Marine Asset Integrity Mapping

Using Multibeam Bathymetry, Topographic Laser Scanning & UAS Photogrammetry
Advances in marine & terrestrial scanning survey techniques together with precise inertial navigation sensors, multi-sensor acquisition systems and cost-effective UAS photogrammetry allow hydrographic surveyors to undertake high-precision marine asset integrity mapping. The benefit of this approach is that it produces a very accurate three dimensional digital elevation model that could be used as a baseline comparative survey to determine the long-term stability of sea walls and breakwater structures for engineering purposes. Marine GeoSolutions have extensive experience in acquiring combined multibeam bathymetry & topographic laser scanning datasets and partnered with Land Surveys to demonstrate the viability of this technology over a...

3D Web-mapping

Integrating Marine Data into Google Earth
Google Earth has become a popular 3D web-mapping viewer, mainly due to the richness of satellite imagery in its primary database. However, the database contains very limited marine data. While the addition of marine data would be welcome, this article explores the use of Web Map Service (WMS) and Keyhole Markup Language (KML) to overlay large-scale multi-beam imagery datasets from the Irish National Seabed Survey into the Google Earth viewer. Over the last seven years the Irish National Seabed Survey (INSS) has returned many terabytes of multi-beam sonar and ancillary data, providing detailed bathymetry data and knowledge of seabed characteristics....

Benthic Habitat Mapping

Utilisation of Multi-beam Backscatter for Ecological Study of the Seafloor
The establishment of multi-beam echo sounders (MBES) as a mainstream tool in ocean mapping has revolutionised approaches towards nautical charting, seafloor geotechnical/geological surveys and benthic habitat mapping. The resolution of bathymetric and backscatter data collected by MBES has improved significantly in recent years through technological improvements of these acoustic systems. Furthermore, developments in data collection and processing of MBES backscatter have resulted in the increasing preferential use of multi-beam technology over conventional side-scan sonar or single beam sonar for these applications. This article explores some recent developments in the methods used to generate benthic habitat maps using multi-beam sonar systems.... (read more)

3D Web-Mapping

Integrating Marine Data into NASA World Wind
While Google Earth is the best known 3D web-mapping viewer currently in the public domain, there are alternative virtual globe viewers available. In particular, this article focuses on the NASA World Wind viewer, using OGC data-dissemination standards and multi-beam sonar data from the Irish National Seabed Survey to illustrate its potential. The creation of a range of innovative GIS tools and systems is enabling the harmonisation and electronic sharing of geospatial data and services across distributed networks. 3D web mapping viewers, such as NASA World Wind, are perhaps some of the most visible of these products. OGC Standards Such developments... (read more)

Coastal Mapping Project Completed

Fugro, USA, has completed data acquisition and processing of the entire United States West Coast under a contract with the U.S. Army Corps of Engineers (USACE) in support of the National Coastal Mapping Program. The company's efforts earned Fugro the USACE 'LCDR Peter Johnson Best Practices Award' at the recent Joint Airborne Technical Center of Expertise (JALBTCX) Annual Airborne Coastal Mapping and Charting Workshop. This major, multi-year effort covered a 1,500m-wide ribbon, extending 500m inshore to 1,000m offshore, along the coastlines of California, Oregon and Washington. Over three survey seasons, approximately 2,000km of coastline were surveyed.  This marks the first... (read more)

Habitat Mapping - Increasing Importance

Two decades ago as CO of a survey ship, I interpreted the SSS-registrations (still on wet paper) twice. Once was for nautical charting purposes and the second, in my own time, was simply to ‘get the most from data collected at high costs’ (my hobbyhorse) when I made a bottom texture chart for those institutions interested. Since then, for various reasons e.g. a growing concern about the environment, more and more habitat studies are now conducted, ranging from baseline surveys to full-blown scientific studies. The multidisciplinary studies are mostly based on hydrographic charting specifications and data quality methods (which I... (read more)
