What Is Raster Data - A raster is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. Web rasters are spatial data models that define space as an array of equally sized cells, arranged in rows and columns, and composed of single or multiple bands. You are already familiar with this data model if you have any experience with digital photographs. Raster data is any pixelated (or gridded) data where each pixel is associated with a specific geographical location. Web the raster data model is widely used in applications beyond geographic information systems (gis). Each cell contains an attribute value and location coordinates. If this sounds familiar, it is because this data structure is very common: Images are often referred to as rasters. It’s how we represent any digital image. Web about raster data.
