We present a method for delineating Urban Structure Types (USTs) using only high resolution RGB images. As the method is unsupervised, it does not require training; the interpretations of delineated USTs are assigned a posteriori. The method utilizes freely available software and performs delineation in a short time even for very large images. A 1-meter resolution image of the entirety of Los Angeles is delineated as an example. We have found seven distinct USTs which were given interpretations
