Vector data has both magnitude and direction. Vector graphics structure is a means of coding line and area information in the form of units of data expressing magnitude, direction and connectivity. An example of vector data is a CAD file such as Microstation or AutoCAD. A line drawn in a vector format is defined by co-ordinates at each end of the line or co-ordinates at the start point and direction and length of the line. As a result the size of a vector file is smaller than that required by a raster file. A vector file will usually have a defined set of elements (e.g. lines, text, ellipses, shapes, curves, grouped complex elements, points) that can be used in the file.
