NOAA's ENC Direct to GIS web portal provides comprehensive access to display, query, and download all available NOAA ENC data in a variety of GIS/CAD formats for non-navigational purposes using Internet mapping service technology. An area of the bottom of a body of water which has been deepened by dredging.(IHO Dictionary, S-32, 5th Edition, 1462) |
* Purpose |
NOAA ENC Direct to GIS Internet Mapping Service is designed to allow for the visualization, querying and downloading of NOAA\x92s Electronic Navigational Chart's (NOAA ENC) data in common Geographic Information System (GIS) formats. |

» Description |
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. |
