Restating the information, here's an alternative description for the given headline:

NOAA is making significant strides in modernising its navigational charting system, with a focus on automating data processes and improving the accuracy of charts. The agency is working on deploying its National Bathymetry Source database, which is expected to significantly expedite the compilation process by automating data precedent and sounding selection.

A key part of this modernisation effort is the re-scheming of NOAA's Electronic Navigational Charts (ENCs). This re-scheming workflow has increased the workload of the Integrated Cataloguer-Encoder (IC-ENC) due to every new re-schemed ENC being a first edition chart. IC-ENC, which validates NOAA ENCs according to the IHO S-58 checklist and distributes the chart products, is involved in NOAA's re-scheming process for various reasons, including validating new, first edition ENCs and coordinating the exchange between new and old cells.

The re-scheming effort started in the band 4 space to produce continuous coverage along all of the US and its territories. NOAA is currently focusing on producing continuous coverage of Scale Band 4 along all of the US and its territories, where approaches to ports will be at 1:40,000 scale. As part of the re-scheme workflow, NOAA provided resources and personnel to coordinate the communication with IC-ENC to maintain a steady, secure production line that can reliably deliver the latest data to ships operating in US ports.

The new chart scheme dramatically increases the number of ENCs in the US suite. The increased number of ENCs may lead to an increase in the cost of management due to the complexity of accounting, such as storage space, coordination, and distribution management. However, the use of binary dependent scales in the re-schemed ENCs will simplify the display of charts in ECS displays and different web-services.

ENCs are vector charts with a standardized content, structure, and format described in the International Hydrographic Organization Standards Publication S-57. They are intended for use in an Electronic Chart Display and Information System (ECDIS), which can also interface with other navigation systems like GPS, RADAR, and echosounders. ECDIS is limited to displaying no more than six different scale charts, one for each of the six ENC scale bands.

While the format, information, and intended uses of NOAA charts have not changed much over the past 150 years, modern navigational systems have become more sophisticated and recreational boaters have started using electronic chart displays. As part of NOAA's ENC-First approach, it has been important to develop cartographic rules that will standardize charting products within the same scale band, independent of geographic location.

Raster Navigational Charts (RNCs) can also be loaded into ECDIS equipment and used together with an appropriate folio of up-to-date paper charts in the absence of ENC. However, NOAA's new plan to standardize a consistent gridded framework that is optimized for digital displays may impact the future of paper charts or raster images that are used in navigation systems.

In addition, the International Maritime Organization (IMO) requires commercial shipping to carry Electronic Navigational Charts (ENC) for planning and displaying the ship's route. Principal ports will be covered at scale band 5, i.e., 1:10,000 scale or 1:20,000 scale. NOAA chooses to divide the scales between Band 5 (Harbor) and Band 6 (Berthing) at 1:5,000 instead of 1:4,000 as recommended by IHO.

NOAA assigns usage bands to its Electronic Navigational Charts (ENCs) based primarily on navigational purpose and scale according to International Hydrographic Organization (IHO) standards. ENCs comply with IHO S-57 specifications and are intended for use in Electronic Chart Display and Information Systems (ECDIS) and electronic charting systems. Usage bands are categories that group ENCs by scale and intended navigational use, ranging from overview to harbor and berthing scales.
