Completeness Report NOAA ENC Direct to GIS data represents current coverage of all ENC Charts. The NOAA ENC Chart Suite is not scheduled to be completed until 2010.As new NOAA ENCs and NOAA ENC editions are created they will be added to the NOAA ENC Direct to GIS data on the first of every month. Conceptual Consistency The NOAA ENC Direct data is derived from NOAA ENC's which conforms to the International Hydrographic Organization Transfer Standard for Digital Hydrographic Data, Special Publication S-57, ENC Product Specification Edition 2.0. NOAA ENC Direct to GIS data has added generalized nautical chart symbology to aid in the visualization of this data. The NOAA ENC database has been built from a combination of charted information as well as original "source\x94 information. NOAA has compiled critical features such as channel limits, aids to navigation, and obstructions from the original documents that were used to put the feature on the paper chart. The objective is to use the most accurate information for features that are critical to the safety of navigation. NOAA uses a number of sources in compiling NOAA ENCS including U.S. Army Corps of Engineers surveys, drawings, and permits, U.S. Coast Guard Local Notices to Mariner, National Imagery and Mapping Agency Notices to Mariners, NOAA hydrographic surveys, and the largest scale paper chart of an area. ENC Direct to GIS data was created by transforming Approach and Harbor NOAA ENC version 2 cells to ESRI's shapefile format using Safe Software\x92s Feature Manipulation Engine.
