The raster file format, along with vector, is one of the main two file types used for digital images. One of the strengths of raster files is the ability to capture detailed graphics and high-quality photographs taken from digital cameras. Explore the key features of raster images, their most common uses, and how they differ from vector images.

What is a raster file? Raster files are images built from pixels — tiny color squares that, in great quantity, can form highly detailed images such as photographs. The more pixels an image has, the higher quality it will be, and vice versa. The number of pixels in an image depends on the file type (for example, JPEG, GIF, or PNG).
Rasters are digital images collected by aircraft, drones, satellites, ground and water-based sensors, digital pictures, and scanned maps. Data stored in a raster format represents real-world phenomena in the following ways: Continuous data represents spectral data, such as satellite, aerial, and drone images, and physical and environmental data ...
A raster image is technically characterized by the width and height of the image in pixels and by the number of bits per pixel. [1] Raster images are stored in image files with varying dissemination, production, generation, and acquisition formats. The printing and prepress industries know raster graphics as contones (from continuous tones).
What are the advantages of raster data? A raster grid format is a data model for satellite data and other remote sensing data. For raster positions, it’s simple to understand cell size. Map algebra with raster data is usually quick and easy to perform. Overall, quantitative analysis is intuitive with discrete or continuous rasters.
Feb 13, 2019 · Raster graphics, also known as bitmaps, store image data as fixed pixels. These pixels, which each represent a single color, are fitted onto a grid (or a “raster” proper, which is where the name comes from). Take a step back, and all those colored pixels form a clear image, just like a mosaic. Higher definition graphic design images require ...

In its simplest form, a raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps. Data stored in a raster format represents ...
