Description:

Abstract:
NOAA's Electronic Navigational Charts (NOAA ENC's) have been developed to support the marine transportation infrastructure and coastal management. The NOAA ENC's are in S-57, a data standard developed by the International Hydrographic Organization (IHO) to be used for the exchange of digital hydrographic data. NOAA ENC's can be used in Geographic Information Systems, (GIS) allowing for broader public access. Many GIS's, however cannot read an ENC's native S-57 format to address this problem. NOAA's ENC Direct to GIS web portal provides comprehensive access to display, query, and download all available large scale NOAA ENC data in a variety of GIS/CAD formats for non-navigational purposes using Internet mapping service technology. Nautical chart features contained within an NOAA ENC provide a detailed representation of the U.S. coastal and marine environment. This data includes coastal topography, bathymetry, landmarks, geographic place names and marine boundaries. Features in an NOAA ENC are limited in that they only represent the geographic region that is depicted in that particular NOAA ENC. By aggregating nautical features from all NOAA ENC's in the creation of GIS data, a contiguous depiction of the U.S coastal and marine environment is achieved.
Purpose:
NOAA ENC® Direct to GIS Internet Mapping Service is designed to allow for the visualization, querying and downloading of NOAA's Electronic Navigational Chart's (NOAA ENC®) data in common Geographic Information System (GIS) formats.

Attribute Accuracy:

Attribute Accuracy Report:
The NOAA ENC® Direct to GIS 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.
Logical Consistency Report:
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 visualazition of this data.
Completeness Report:
NOAA ENC® Direct to GIS data represents current coverage of all large scale Harbor and Approach (1:150,000 to 1:50,000 or larger) ENC Charts. The NOAA ENC® Chart Suite is not scheduled to be completed until 2007. As new NOAA ENC®s and NOAA ENC editions are created they will be added to the NOAA ENC Direct to GIS data on the first of every month

Lineage:

Process Step:

Process Description:
The NOAA ENC® database has been built from a combination of charted information as well as original ""source"" 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 ENC®S 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's Feature Manipulation Engine.
