PLA Hydrographic Service: Published Surveys
Latest Editions and Corrections
The interactive map and table below detail the charts (River Main Surveys) published by the PLA of the River Thames from Teddington to Southend. These products are periodically updated for navigationally significant changes as new survey data is captured and are the largest scale charts available. Geo-referenced images of the charts are provided for planning use in the central London area and further information on their use can be found at the bottom of this page. Printed copies of individual charts and folio sets are available to buy direct from the PLA shop.
The PLA also produce smaller scale skeleton Miniplots depicting the latest significant soundings and contours from routine surveys which are intended to compliment, not replace, published nautical charts. Smaller scale Admiralty Charts produced by the UK Hydrographic Office are also available downstream of Tower Bridge and include port approaches in the Thames Estuary and may be a more appropriate scale for some users.
Mariners should ensure Nautical Publications and Charts are always kept up to date with corrections. For PLA chart products, see the chart corrections advices (CCA’s) on this page or for Admiralty products see Admiralty Notices to Mariners (NMs).

Geo-referenced images of the central London charts are made available to support planning and river works license applications that require details of the scheme to be super-imposed on an appropriate scale navigation chart. These images are referenced to the Ordnance Survey National Grid and can be readily used within a GIS environment.
These go-referenced images can also be imported into AutoCAD, instructions for which can be found here. A base AutoCAD drawing with chart outlines which is required to correclty scale the geotiffs in some versions of AutoCAD can be downloaded here.
