Analyzing cartographic information to improve nautical chart coverage
Presenter: Colby Harmon, NOAA - Marine Chart Division
The National Oceanic and Atmospheric Administration (NOAA) is undertaking a program to enhance and standardize its suite of Electronic Navigational Charts (ENC). ENCs, used by professional mariners and recreational boaters alike, were digitized in the 1990s from paper nautical charts having a variety of shapes, sizes and scales. A new scheme with a standardized, gridded layout has been proposed, based on criteria, such as existing U.S. and Canadian ENC coverage, the size of ports and positions port entry features, and vessel traffic volume. This presentation describes the criteria and the analytical methods used to create and validate the new scheme.
This presentation was made at the 2018 annual meeting of the North American Cartographic Information Society (NACIS) in Norfolk. For more information on NACIS, check out [ Ссылка ].
