If your project requires scalable shapes and solid colors, vector is the best choice, but if your project requires complex color blends, raster is the preferred format. Raster images are best for digital photos and print materials. A vector graphic is rendered by a mathematical manipulation referenced by co-ordinates. Raster graphics use pixels (dots) whereby a graphic is made up of a large number of pixels, each pixel having a location & colour value in a grid-like format. Their native files are needed for coin designs, laser engraving, t-shirts, patches, etc. The key difference between Raster and Vector graphics is how they are structured. They're also used in lower thirds for videos, web-based objects and rendering 2D or 3D computer animation. Raster-based software (e.g., Adobe Photoshop)Ī vector graphic's small file size and scalability make it uniquely suitable for use in digital printing from business cards to billboards. Vector-based software (e.g., Adobe Illustrator).Digital printing (e.g., business cards, billboards).However, a high resolution image printed at a small size will cause the pixels to "cram" together and will make the image look as unprofessional as not having enough pixels in a large image. Resolution limits the size the image can be scaled up without being able to see pixels. The lower the number of pixels, the lower the resolution. More pixels result in better quality at the same or larger sizes as the original, but this also increases the size of the file and the amount of space it takes to store the file. Each image can only contain a fixed number of pixels the amount of pixels determines the quality of the image. These images are created by digital cameras, by scanning images into a computer or with raster-based software. Pixels appear like little squares on graph paper when the image is zoomed in or enlarged. Raster images are made of pixels or tiny dots that use color and tone to produce the image. Data integration is a common task in GIS, where vector data from a census and raster data from a remote sensing image are combined to analyze the relationship between population and land use. Feature layer data references feature classes, which are stored in geodatabases. Feature layers Feature layers represent geographic objects as vectors and can be symbolized in a variety of ways depending on their attribution. Because they consist of lines and anchor points, the size of the file is relatively small. The layer type contextual tab set appears in the ribbon. These graphics are also device-independent, which means their quality doesn't depend on the number of dots available on a printer or the number of pixels on a screen. Their lines are sharp, without any loss in quality or detail, no matter what their size. Because these graphics are not based on pixels, they are known as resolution independent, which makes them infinitely scalable. A comparison between the travel-time estimates derived from both. These graphics consist of anchored dots and are connected by lines and curves, similar to the connect-the-dot activities you may have done as a kid. The Cost of Hauling Timber: A Comparison of Raster- and Vector- Based Travel-Time. Vector graphics are also known as scalable vector graphics (SVG).
