NOAA ENC Direct to GIS  NOAA Office of Coast Survey

ENC Direct to GIS allows users to display, query, and download all available base editions of NOAA ENC® data in a variety of GIS/CAD formats, using Internet mapping service technology. Nautical chart features contained within a NOAA ENC provide a detailed representation of the U.S. coastal and marine environment. The data, updated weekly, is organized using S-57 object classes. Features in a single NOAA ENC are limited in that they only represent the geographic region that is depicted in that particular NOAA ENC cell. By aggregating nautical features from all NOAA ENC in the creation of GIS data, a continuous depiction of the U.S. coastal and marine environment is achieved.


Graphical Interface (Experimental)

Find out what enhancements are available in version 10.1!

All object classes that are available in ENC Direct to GIS can be viewed and extracted in a variety of GIS/CAD formats. The download function is designed to provide seamless data in the geographic region of your view frame. If a feature extends beyond the view frame, the feature is clipped and exported to reflect what is in the view.

Caution Note: The ArcGIS 10.1 server has known issues with the extraction tools that may cause a failure in obtaining data. Recommend selecting multiple smaller areas rather than one large area when extracting coastal features. If you need assistance in obtaining ENC data for your GIS project please send an inquiry and we will work with you on obtaining the dataset.
