Description 
Summary

Bathymetric, topographic and tidal data are gathered and processed to make fair sheets of depths related to local chart datum. Fair sheets of critical areas are distributed internally as working copies; others are used as a basis for the published charts. Extensive bathymetric data of the area is now available in digital (ASCII xyz) format. The PLA Hydrographic service will have a large amount of the data in S57 by the end of 2001
