High Resolution Surveys for Transport for London / London Underground

Geodesea Ltd has recently been contracted by the PLA to acquire, process and render high resolution surveys of the numerous tunnel crossings under the River Thames for Transport for London & London Underground.

POSMV INS and Reson MBES survey data was acquired using Hypack/Hysweep and processed using Hypack/Hysweep & Fledermaus software.

These surveys assist in the ongoing monitoring for scour and accretion of the river bed in the vicinity of the tunnels.
