A Raster Chart is a type of digital map that uses a grid of pixels to represent geographic information. Each pixel contains data about a specific area, such as elevation, temperature, or land cover. Raster charts are commonly used in fields like geography, meteorology, and environmental science to visualize complex data in a clear and accessible way. These charts can be created from various sources, including satellite imagery and aerial photography. Unlike vector graphics, which use points and lines, raster charts are resolution-dependent, meaning their quality can decrease when zoomed in. They are essential tools for analyzing spatial patterns and trends in data.
