Two reschemed band 2 (general scale) ENC cells already exist over the Arctic Ocean. The map viewer shows that work started on the Alaskan North Slope, the Great Lakes, the Florida Gulf Coast, and Down East Maine. Click on a cell on the map to get more information about a specific ENC. To see the progress, turn on each ENC usage band one at a time from the Layer List on the left side of the display. Individual ENCs are categorized into six usage bands, which correspond to traditional chart usage types (or scale ranges) from the smallest scale “overview” (band 1) to the most detailed, largest scale “berthing” (band 6). The green cells represent completed harbor scale (band 5) ENCs. New Jersey and surrounding area displayed in the new web map service. Once it enters the quality check (yellow) phase, it generally only takes a few more weeks to be released to the public. The time it takes to create individual ENCs varies, depending on its scale, the area which it covers, and other factors. The map viewer shows where new ENC cells are planned (in open blue rectangles), cells actively being created (in red), cells undergoing final quality checks at IC-ENC (in yellow), and completed cells released to the public (in green). This process was first announced in the National Charting Plan and is explained in detail in Transforming the NOAA ENC®. Improvements to the ENC suite involves replacing this puzzle-piece layout with a rectangular grid of ENCs (referred to as rescheming), often providing larger scale and more detailed coverage than the existing paper charts. The current ENC scheme is based on the extents of the paper nautical charts from which ENCs were originally digitized. The public can now view ENC project status from the planning and creation stages all the way to completion, keeping them better informed when these enhanced navigational charts become available. The data is also available as a GIS map service. NOAA’s Office of Coast Survey released a new and improved map viewer featuring the status of NOAA electronic navigational charts (NOAA ENC®) as they undergo major improvements.
