🔍 Key Concepts

• Raster vs. Vector charts in electronic navigation systems • How image (picture) files differ from data/object files • Typical file structure and layering used in electronic chart systems

💭 Think About

• Think about how a scanned paper chart would be stored in a computer. Is it saved as many objects, or more like a single image? • Which chart type (raster or vector) usually allows multiple layers of information to be turned on and off? • Consider how international standards (IMO/IHO) treat raster and vector charts—do they recognize both, or only one?

✅ Before You Answer

• Verify what "raster" means in general computer graphics (pixels vs. objects). • Check which chart type is often described as a "picture" of the paper chart. • Confirm whether IMO/IHO standards apply only to one format or to more than one electronic chart format.
