They also work better with straight lines or sweeping curves.ĭrawing programs, like Adobe Illustrator and Corel Draw, primarily use a vector-based drawing mode to allow for scalability and clean lines. They are generally filled with a solid color or a gradient but can’t display the lush color depth of a raster. The geographical problem you’re trying to solve and the maps you have to solve the problem most often make that decision for you. ![]() ![]() Vector images do have some drawbacks, however. The Raster vs Vector GIS question is rarely one you need to worry about these days. Vector images can also result in smoother lines because the lines are not hand drawn. With Geoapify APIs you can create a custom map from scratch. You can easily color, or recolor, a vector-based image very easily using a drawing program. Geoapify offers raster and vector tiles with different styles for your map. The vector points spread out and the computer just redraws the image. If you resize a vector-based image, it loses little or no detail. In the printed image, the vector points would be invisible.īecause the computer only has to keep four points in its memory, it is much easier for the computer to edit vector-based images. Here are the three most important differences between raster and vector. Each vector point has information in it telling your computer how to connect each point with straight or curved lines, and with what color to fill in the closed shape. These “vector points,” basically allow your computer to play Connect the Dots. In a vector-based program, the same square would be made of only four dots, one on each corner. In a raster-based image creation program, a square would be made of thousands of pixel dots. A vector-based program does not render images on a pixel-by-pixel basis. ![]() Vector-based programs approach image creation in an entirely different manner. The main difference between raster and vector graphics is that raster graphics carry the pixels whereas vector graphics carry paths. A raster graphic (also called bitmap) is basically a large grid, filled with boxes called pixels When you stand far enough away from the grid, the individual. They can contain millions of pixels and incredibly high levels of detail.
