Which mode indicates that ECDIS is utilizing raster charts?

• A. RCDS
• B. ENC
• C. ARPA
• D. CSM

Answer: (A)

The correct choice indicates that ECDIS is utilizing raster charts. Raster charts are typically bitmap images of paper nautical charts that are scanned and processed for digital use. RCDS, which stands for Raster Chart Display System, is specifically designed to handle these types of chart data. In RCDS mode, the ECDIS system displays raster charts, allowing for the integration of these images into its navigational functions. This is significant because raster charts may not have the same features or functionalities as vector charts, such as those provided by ENC (Electronic Navigational Chart), which relies on a different kind of data structure and representation, focused on vector graphics. ARPA (Automatic Radar Plotting Aids) and CSM (Chart Standardization Methods) pertain to radar systems and chart management practices, respectively, and do not indicate the use of raster charts in ECDIS.
