WebOrthonormal means these vectors have been normalized so that their length is 1. Orthogonal vectors are useful for creating a basis for a space. This is because every point in the space can be represented as a (linear) combination of the vectors. So for example in 3D space, x= [0,0,1] y= [0,1,0] and z= [1,0,0] form an orthornormal basis.
