Raster charting
Raster charting is a method of creating maps using pixel-based images, similar to digital photographs. These maps are made up of many tiny squares (pixels), each with specific color and detail information that collectively represent geographical features like coastlines, water depths, and terrain. Raster charts are detailed and useful for navigation, especially in marine and coastal areas. While they provide detailed visual information, they can lose clarity when zoomed in too far. Think of it like a high-resolution image; it offers rich detail but relies on a fixed set of pixels that don't change size or resolution.
