    Author : KUAN-YU HUANG; [2015]
    Keywords : Open geographic data; box counting fractal dimension; head tail breaks classification; lacunarity; natural cities;

    Abstract : A city consists of many elements such as humans, buildings, and roads. The complexity of cities is difficult to measure using Euclidean geometry.
