This document provides information on different types of digital images and file formats. It discusses the differences between vector and raster images, with vectors using mathematical descriptions and rasters using a grid of pixels. Common file formats for images are also outlined, including their advantages and disadvantages. GIF supports up to 256 colors and lossless compression, while JPEG can store more colors but uses lossy compression. TIFF is a popular archiving format that maintains image quality but results in large file sizes. Vector data has benefits for accuracy and analysis while rasters are better for modeling continuous data.
