High Resolution Survey Projects

Overview

The PLA Hydrographic Service with its three survey craft fitted with high resolution multibeam echosounders together with experienced surveyors and crew are becoming increasingly involved in providing survey support to a range of engineering and environmental projects.  The Service is also using terrestrial laser scanning techniques to survey structures and areas of the foreshore above the water line to produce a seamless 3D image of a site.  Obstructions and wrecks can also be surveyed in incredible detail providing valuable information for both engineers, divers, geologists and archaeologists.

The smallest of the three survey vessels, "Galloper" can be easily transported by road and mobilised to anywhere in the UK.

As well as the standard range of chart products available for the River Thames, the Service can also provide bespoke plots at varying scales, ASCII XYZ points and 3D visualisation of data, together with the freeview software.   Benefitting from a close working relationship with the Geomatics department of University College London and the using the latest in Geographic Information Systems, the Service can handle and transform data in a number of geodetic projections and datums.
