Why are the lines and shapes of features jagged instead of smooth?
On a printed topographic map, curved lines and shapes are very smooth. When that same information or data is viewed in a format that is compatible with your Web browser, it gets converted into a picture or image that is made up of small pixels. Because of this, you are not seeing an actual line but a line that is made up of pixels which appears jagged.
