A Vector Chart is a type of digital map that uses mathematical formulas to represent geographic features. Unlike raster charts, which are made up of pixels, vector charts can be scaled to any size without losing quality. This makes them ideal for navigation and detailed analysis, as they can display information clearly at various zoom levels. Vector charts are commonly used in applications like GPS navigation, marine navigation, and geographic information systems (GIS). They can include various data layers, such as roads, waterways, and terrain, allowing users to interactively explore and analyze spatial information efficiently.
