![]() The database for displaying ENCs was first created in 1993, which by today’s standards, is considered old and needs updating. New techniques, equipment, and technology is now available to create improved vector or electronic charts (ENCs), which is NOAA’s goal for the next few years. The Coast Survey created and published the first paper charts more than 180 years ago. The Why– Raster charts and electronic images of raster charts (RNCs) have been around for a long time. The existing print-on-demand paper raster charts will also be going away. ![]() This also means that the existing 5-digit raster chart numbers will be retired. By January of 2025, NOAA will no longer produce raster chart products. This includes digital images of raster charts and booklet charts. What Is Going Away– starting in 2020, NOAA will begin phasing out raster charts. Army Corps of Engineers produce raster charts for inland waters, and the Canadian Hydrographic Service produces raster and vector charts for the waters of Canada. NOAA isn’t alone in preparing raster charts. Electronic navigational charts are NOAA’s only nautical vector product. NOAA raster chart products include paper nautical charts, raster navigational charts, and booklet charts. ![]() Records associated with each feature further describe its color, shape, purpose, or other attributes. Vector charts are digital data that store features as pairs of latitude and longitude coordinates (as opposed to a matrix of pixels). The electronic image comprises rows of color pixels, or dots of ink, which form the symbols, lines, and tints that compose a chart. Raster charts are digital or paper images of traditional nautical charts created by cartographers. What Is Here Now– boaters currently have a choice of Raster Navigation Charts (RNC) or Vector Electronic Navigation Charts (ENC). However, NOAA’s plan to phase out all raster products is attracting much attention. The future of charts is a multifaceted subject area. Together, these two NOAA documents describe the future of nautical charts. Then in November 2017, following a comment period, NOAA published their National Charting Plan that included a focus on vector chart products. More than two years prior, NOAA published a Draft National Charting Plan, which included plans to phase out raster charts. November of 2019 NOAA published their timeline and plans to phase out all raster chart products in favor of vector charts by January of 2025.
