Title: NOAA ENC Direct to GIS
Short Name: enc_direct
Status: In Work
Publication Date: 2001
Abstract:

NOAA's Electronic Navigational Charts (NOAA ENCs) have been developed to support the marine transportation infrastructure and coastal management. The NOAA ENCs 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 ENCs 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 ENCs 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.

Notes:

1527

Supplemental Information:

The ENC data are available in several different Scale Bands. Update: Band categories 4, 5 and 6 are no longer packaged together:

Overview (scale band category 1 = 1:1,500,001 or smaller),

General (scale band category 2 = 1:600,001 - 1:1,500,000),

Coastal (scale band category 3 = 1:150,001 - 1:600,000),

Approach (scale band category 4 = 1:50,001 - 1:150,000)

Harbor (scale band category 5 = 1:5,001 - 50,000),

and Berthing (scale band category 6 = 1:5,000 or larger)

The data are available in either "North American Datum 1927" (Clarke Ellipsoid 1866) or "World Geodetic System 1984" geodetic datums. Object class are listed under Entity Type with each applicable Geometric primitive suffix for point, line and/or area (examples: Built_Up_Area_area and Built_Up_Area_point).

Data Quality

Accuracy:

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.

Horizontal Positional Accuracy:

The NOAA ENC Direct to GIS data is derived from data that conforms to the International Hydrographic Organization Transfer Standard for Digital Hydrographic Data, Special Publication S-57, ENC Product Specification Edition 2.0.

Vertical Positional Accuracy:

The NOAA ENC Direct to GIS data is derived from data that conforms to the International Hydrographic Organization Transfer Standard for Digital Hydrographic Data, Special Publication S-57, ENC Product Specification Edition 2.0.

Completeness Report:

NOAA ENC Direct to GIS data represents current coverage of all published ENC Charts. As new NOAA ENCs and NOAA ENC editions are created they are added to the NOAA ENC Direct to GIS dataset.

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 visualazition of this data.

Lineage

Process Steps

Process Step 1

CC ID: 493934
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 ENCS including U.S. Army Corps of Engineers surveys, drawings, and permits, U.S. Coast Guard Local Notices to Mariner, National Geospatial-Intelligence 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 ArcSDE format using Safe Software's Feature Manipulation Engine.
