Old hydrographic surveys and old nautical charts are filled full of errors or inaccurate depth and coastline information. These errors or lack of accurate information is as a result of inferior equipment and lack of 100% bottom coverage over large areas of the sea bottom. Coastline information errors are the result of poor positioning of original data relative to present day GPS data. These inaccuracies and other older information or perhaps no information as is the case in unsurveyed areas may be the cause of ship groundings. I can help determine whether these errors are the cause of these expensive accidents.
