Innovative Hydrography; delivering a workflow for Acquisition, Processing, Visualization and Sharing for all modalities of today’s shallow water multibeam echosounders

Today’s shallow water multibeam echosounder are capable of efficiently delivering bathymetry, backscatter and water column data types. To benefit from this technology, Hydrographers are having to adjust their data collection and data processing workflows to deliver detailed and accurate information in an effective manner to a wider variety of End Users.

Improved Operational Decision- Making for USV Fleet Surveys

Significant interest in autonomous and unmanned vehicles has developed within the survey community during the last few years. Unmanned Surface Vehicles (USV’s) are being considered for tasks such as data gathering in waters considered too shallow for manned vehicles and in areas presenting hazardous operating conditions. Looking forward, the concept of operating a fleet of autonomous and unmanned surface vehicles, with or without manned vessels as part of the fleet, holds great promise to improve survey efficiency.

Listening to your customer is key when designing a new product

As a manufacturer, we are always striving to create products that we believe to be what the end users desire. The technology around which our lives revolve these days has had a strong influence over what we expect from products in every area of life. For instance, I have my smartphone, tablet and laptop; I have high speed access to information and data via the internet. Hardware is easily charged, memory is plentiful and expandable, quality is good and costs are reasonable. So, these are the standards I expect from the equipment I am about to use when hydrographic surveying. Valeport has led the way in sound velocity technology for more than a decade and our latest addition to the portfolio, the SWiFT SVP, was designed from the outset with customer feedback front of mind and a practical understanding of what customers actually want from an instrument.

SUB-BOTTOM PROFILING ACQUISITION & PROCESSING IN HYPACK®

The newly launched HYPACK® SUB-BOTTOM is a sub-bottom profiling acquisition and processing software package designed for marine geophysical, engineering & geotechnical site surveys, dredging, mining applications. It’s a simple and easy-to-use solution for most sub-bottom profiling survey requirements. Basic sub-bottom profiling acquisition & processing has been available in HYPACK for the past few years, but during the first quarter of 2017 a considerable amount of effort has been put into improving the stability, memory allocation and features of the program. This article is highlights some of new features and functionality of HYPACK® SUB-BOTTOM.
